1 / 15

Q. Are windows included in framing?

A. No, Only framing in house construction includes the vertical and horizontal members of exterior walls and interior partitions. These members, referred to as studs, wall plates and lintels, serve as a nailing base for all covering material and support the upper floors, ceiling and roof.

B. Once framing is complete, an inspector will come out again to verify that everything has been done to code. After that, exterior finishes like plywood and house wrap will be applied to seal off the inside from the outside.

C. Yes, framing, or the process of erecting the structural outline of a new building, is a critical step in any building construction project. This structural outline will be what holds the walls, siding, windows, doors, and roof. It's also where the plumbing and electrical wiring is concealed.

D. Framing a home usually takes 5-8 weeks. It also depends on the type of home you are building, the size of the home you are building, and the location. So, at this point, if all has gone according to plan you can expect to be on your 3rd month when your framing begins. Included in framing is the roof of the home.

2 / 15

Q. What are the two most common stud spacing?

A. Standard two-by-four studs actually measure about 1 1/2 inches by 3 1/2 inches. Studs are installed in vertical rows between the walls top and bottom plates. The vertical members of walls, are typically spaced every 16 inches (generally called 16 inches on center, or 16” OC).

B. Rectangular or square ducting comes in standard sizes ranging from 3 inches by 7 inches to 35 inches by 40 inches. Sizing is based on airflow needs per cubic foot per minute, as well as velocity.

C. Some typical US Customary trade sizes for conduit are ½, ¾, 1, and up to 4. Outside the US, conduit sizes are typically measured in millimeters and are based on the outer diameter. Some common metric outer diameter sizes are 20 mm, 25 mm, 32 mm, 40 mm and 50 mm.

D. Most plumbing codes and building codes require support for horizontal pipe lines every 3 feet for pipe in 1/2”-1” diameters, and every 4 feet for pipe with diameters greater than 1”. Support spacing should be in accordance with applicable plumbing and building codes.

3 / 15

Q. What are four major elements of advanced framing?

A. Plumbing system has three major components: pipes and fittings, drainage, and fixtures.

B. Four main types of HVAC systems. There are split systems, hybrid systems, duct-free systems, and packaged heating and air systems. EacB. these types of HVAC units have pro's and con's, and knowing these factors can help you decide which is best for you

C. Advanced framing typically includes 2x6 wood framing spaced at 24 inches on center and some or all of the following techniques: single top plates, two-stud corner junctions, minimal use of jack studs and cripples, and the elimination of redundant studs and unnecessary blocking and bridging.

D. The basic electrical quantities are electrical current and voltage, electrical charge, resistance, capacitance, inductance and electric power.

4 / 15

Q. What is the most common type of framing?

A. Non-combustible and Masonry Non-Combustible are different construction types. Rates usually vary HIGH for these two construction types.

B. Platform framing is the most common framing technique in modern residential construction. Where each story is framed on top of the previous one. Builders will frame in one-story platforms of typically eight or nine-foot-high stud walls resting on a subfloor — the platform.

C. Framing materials are usually wood, engineered wood, or structural steel. The alternative to framed construction is generally called mass wall construction, where horizontal layers of stacked materials such as log building, masonry, rammed earth, adobe, etc. are used without framing.

D. Wood frames are by for the most common and popular type of house frame. Homes built from these types of frames are also called "stick-built" homes. Wood frames are easy to build, and the materials are also extremely easy to come by, hence their popularity.

5 / 15

Q. What is the most common type of framing?

A. Non-combustible and Masonry Non-Combustible are different construction types. Rates usually vary HIGH for these two construction types.

D. Common studs are vertical members which transfer loads vertically to bottom plates. They are usually evenly spaced to suit loads, lining and cladding fixing.

6 / 15

Q. What are the three types of framing for wood structures?

A. Frame (Frame ISO 1): Risks under this construction type have exterior walls and bearing walls that are of wood or light-gauge metal. This construction type will also include risks that are of brick veneer, stone veneer, or stucco.

B. In general, there are four different types elements you can use to create a frame within your shot: architectural, natural, geometric shapes, and light/shadow.

C. Since the 1830s, two methods of wood framing have been used to facilitate building a structure: balloon framing and platform framing.

D. Modern wood framing essentially includes three types: balloon, platform and semi-balloon framing. With long lumber lengths, vertical load-bearing framing studs run continuously from foundation to roof. Intermediate horizontal floor joists are nailed to the sides of the vertical studs and bear on a ledger.

7 / 15

Q. What is a rough framing city inspection?

A. Rough framing. The rough framing is the first part of the four-way inspection. At this stage the house will be completely framed with exterior doors and windows installed. There are literally hundreds of items that the inspector will look for during the framing inspection the most important of which are structural items. Once framing is complete, an inspector will come out to verify that everything has been done to code.

B. Rough framing consists of the creation of a structure based on vertical components, known as studs, which provide a stable frame for interior and exterior wall coverings. Horizontal elements called joists, run the length of the floor, or between walls or beams. The joists support ceilings and floors.

C. There are a number of reasons why electrical work done on your home might fail inspection. Some of the most common are: Lack of GFCI protection on outlets in kitchens, bathrooms, or other areas where water might be involved. Exposed wiring or open-sliced wires.

8 / 15

Q. What does rough framing include?

A. For most homes, construction framers measure, cut and assemble lumber for the walls and subfloor, adding anchors and other vital structural supports. A rough framing carpenter also measures and attaches studs around the spaces for doors and windows, and sets joists for the ceiling, then trusses for the roof. Installation of floor joists, floor sheathing, layout and installation of walls, hanging and nailing of shear panels, setting and bracing roof trusses and rafters, installation of starter board, roof sheathing, and fascia board installation.

B. When carpenters focus on the numerous wood details that complete the interior of the home.

C. All the carpentry encompasses all work done inside a house after framing, sheathing, wiring, plumbing, insulation and drywall have been installed.

E. The exterior and interior finishing of buildings and structures to enhance their service and aesthetic look.

9 / 15

Q. What is the purpose of a rough opening in framing?

A. A rough opening is the opening that is left in a frame wall where the window frame will sit. The measurements of the rough opening will be important for you to choose the right window frame size. The actual window size will be lesser as the frame will have a header, sill, and vertical trimmers that will have to fit in.

B. Recommended rough opening is between 3/4" (19mm) - 1" (25mm) larger than the window width and height. Ensure that the rough opening is plumb, level and square, and the walls in the opening are not twisted.

C. Framing rough opening sizes are really quite simple. Just add 2″ to the width of the actual door size. You should add 2-1/2″ to the height of the actual door. This will give you room to space the door frame off of the sub-floor.

D. The rough opening should be 49 by 82 for a 48-by-80-inch door. This allows for 1/2-inch-thick drywall on both sides and at the top, 80 inches for the doors and hardware, and a 1-to- 1 1/2-inch space under the door.

E. All The Above.

10 / 15

Q. What are the two types of framing?

A. Insulated Concrete Forms (ICFs) ICF wall systems produce strong, energy-efficient, durable, and disaster-resistant framing for a house.

B. Light Wood Framing

C. Concrete Masonry Units (CMUs) Framing

D. Steel Frame Construction

E. All of Above.

11 / 15

Q. What are the two types of framing?

A. There are several types of home framing options available, but the two most common types are platform framing and balloon framing.

B. The most common framing technique in modern residential construction is platform framing, in which each story is framed on top of the previous one. Builders will frame in one-story platforms of typically eight- or nine-foot-high stud walls resting on a subfloor—the platform.

C. Principal types of framing for light structures: western, balloon, and braced.

D. Framing your house is an ambitious yet exciting project. There are two basic house framing methods: the platform method (most common) and balloon construction (used in older grand houses) and in both methods the wall studs and ceiling and floor joists are repeated over every 16 or 24 inches of the frame.

12 / 15

Q. What is included in rough carpentry?

A. Rough carpentry focuses on the framing of a building. This means the carpenters are responsible for the wood or metal support systems the make up a structure's walls, floors, and roof. Think of the frame as the building's skeleton.

B. CDX is veneer plywood, which is manufactured by gluing and pressing together sheets of wood. The letters C and D represent the grades of either side of the plywood, while X stands for exposure.

C. Plywood sheathing (OSB or plywood) is often mistaken for plywood underlayment. They are not the same. Plywood sheathing is most often used to construct the structural sub-floor. Plywood sheathing can either be OSB or all plywood

D. There are four grades of plywood: A, B, C and D. The grade refers to the quality and appearance of the plywood's face and back veneers. A has the highest quality and is the most expensive, and D is the least expensive. A-grade plywood features a smooth, sanded surface without knots

13 / 15

Q. What is the most common spacing for wall studs?

A. To summarize, studs at 24-inch spacing will save money and resources, and are safe. With 2x6s, it's a no-brainer for most residential construction—they're plenty strong in nearly any configuration. With 2x4 studs you can also get by with 32-inch spacing, but walls should be 9 feet tall or less and the loads modest.

B. Studs are vertical boards -- they are generally 2 x 4's, although they actually measure 1 1/2 inches thick and 3 1/2 wide -- and are installed at intervals inside a wall to strengthen it and support the wallboard, paneling or plaster.

C. You should always find studs spaced either 16 or 24 inches on-center (measured from center to center) along the wall and run between the floor and ceiling.

D. How far apart are the studs in my home? They're always spaced either 16 or 32 inches on center (measured from center to center) along the wall and run between the floor and ceiling. Drywall or lath (for plaster walls) attaches to the edge of the studs.

14 / 15

Q. How big should a rough door opening be?

A. The frame should be 3/16" wider than the slab (1/16" clearance on the hinge jamb and 1/8" clearance on the strike jamb) and tall enough (usually 1/4" - 1/2" taller) to allow 1/8" clearance on the head jamb and allow the slab to operate without rubbing on any flooring.

B. Framing rough opening sizes are really quite simple. Just add 2″ to the width of the actual door size. You should add 2-1/2″ to the height of the actual door. This will give you room to space the door frame off of the sub-floor.

C Width is a jamb-to-jamb measurement of the space where the door slab will go, measure the jamb (hump to hump), add 2 1/2" (Frames generally measure 1 1/4" thick each x2), add 3/4" to unit width measurement, and the final sum will be your opening width.

D. The height for all passage doors must be a minimum of 80 inches and the standard width sizes for interior doors are 24”, 28”, 30”, 32” and 36”. The minimum recommended door width to allow persons with disabilities' to pass through is 36 inches.

E. All The Above.

15 / 15

Q. What are four major elements of advanced framing?

A. Advanced Plumbing system has three major components: pipes and fittings, drainage, and fixtures.

B. Advanced House framing, sometimes called optimum value engineering (OVE), refers to framing techniques designed to reduce the amount of lumber used and waste generated in the construction of a wood-framed house.

C. Advanced Framing typically includes 2x6 wood framing spaced at 24 inches on center and some or all of the following techniques: single top plates, two-stud corner junctions, minimal use of jack studs and cripples, and the elimination of redundant studs and unnecessary blocking and bridging.

D. Advanced framing is less expensive than conventional framing because it is more resource efficient than conventional framing. By optimizing framing material use, the builder can cut floor and wall framing material costs by up to 30 percent while reducing framing installation and labor.

Am-Cat Restoration Rough HVAC Certification

Rough HVAC Technicians may hone their skills in a wide range of roughing in Ducking, all rough HVAC technicians are Am-Cat certified.

1 / 6

Q. What heats and cools your house?

A. Instead of sending water through the heater, cold water service lines run directly to every water appliance in the home. Plumbers install these pipes in straight lines, 90 degree angles, or slight downward slopes to facilitate easier flow.

B. Furnaces and heaters put heat into the air to make your home warmer; air conditioners remove heat to make your home cooler. All heating and cooling units burn fuel. Air conditioners use electricity. Most home heating systems use gas or fuel oil; other systems use electricity.

C. If there's no room between the lock and frame, slide the card in the space above the lock and between the door and the frame. Angle the card towards the frame. Then, swipe quickly downward. To open a locked interior door with a screwdriver, first push the screwdriver as far as you can into the hole on the doorknob.

D. Solar (such as photovoltaics) generally using solar panels, wind using a wind turbine (windmill) to turn a generator for your power, geothermal which is basically heat extraction from the earth, and micro-hydro using the natural flow of water.

2 / 6

Q. Is heating and cooling system the same?

A. A package HVAC unit combines multiple units, such as an air conditioner and heater, into a single unit. The unit is usually placed outside. Split systems, on the other hand, divide each system into its own unit, so your heater and air conditioner are separate.

B. HVAC can include heat pumps and gas furnaces as well as air conditioning units. This means HVAC deals with both heating and cooling. Companies will use the terms interchangeably because many AC repair services deal with both heating and cooling solutions. HVAC also covers ventilation and ductwork.

C. Yes, A thermostat registers the temperature and kicks off the HVAC system, heat pumps have the same parts as a split-system air conditioner and work in the same way when they're needed for cooling.

D. First and foremost, HVAC stands for heating, ventilation, and air conditioning. This system provides heating and cooling to residential and commercial buildings.

E. All THe Above.

3 / 6

Q. How long does an HVAC system last?

A. Generally, brass pipes can survive between 80-100 years. However, brass pipes are used less frequently today than they once were, as they often contained trace levels of lead (we'll get to that later.) Galvanized Steel: Galvanized steel piping also last between 80-100 years.

B. 15 to 25 years a heating or cooling system is a significant investment, and it only makes sense to get as much use out of it as possible. In general, most HVAC systems will last from 15 to 25 years but depending on the type of system and other contributing factors, that estimate can be highly variable.

C. As a general rule, home wiring can last past 50 years. But it can also be far less than this—for example, if the wiring was badly installed in the first place or amateur modifications were made to it at some point.

D. Slate, copper and tile roofs, which are on the upper end of the price spectrum, can last more than 50 years. Homeowners with wood shake roofs should expect them to last about 30 years, while fiber cement shingles last about 25 years and asphalt shingle/composition roofs last about 20 years, the NAHB found.

4 / 6

Q. What is HVAC ventilation ?

A. Natural ventilation can generally provide a high ventilation rate more economically, due to the use of natural forces and large openings.

B. Supply Ventilation.

C. Ductwork refers to the system of ducts (metal or synthetic tubes) used to transport air from heating, ventilation and air-conditioning (HVAC) equipment throughout your home. Properly installed and well-maintained air ducts are a key component of indoor air quality and home comfort.

D. MECHANISED FANS. In some cases, a natural ventilation solution isn't possible due to the design and location of building.

5 / 6

Q. What is used to keep the air clean in HVAC systems?

A. Portable air cleaners, also known as air purifiers or air sanitizers, are designed to filter the air in a single room or area. Central furnace or HVAC filters are designed to filter air throughout a home.

B. An air scrubber is a device that attaches directly to the ductwork of your HVAC system. It removes air pollution, VOCs, surface contaminants, pet dander, odors and dust. It provides a cleaner, healthier and more efficient home.

C. To clean your HVAC filter, first turn off your heating or air conditioner. Locate your HVAC unit's service panel, and open it to find the filter. Clean the filter with running water, such as your sink or garden hose. Allow your HVAC filter to air dry completely before reinserting!

D. An air scrubber is a device that attaches directly to the ductwork of your HVAC system. It removes air pollution, VOCs, surface contaminants, pet dander, odors and dust. It provides a cleaner, healthier and more efficient home.

6 / 6

Q. How does HVAC ventilation work?

A. The HVAC system does not bring fresh air into a building. A space is heated and cooled using recycled indoor air, with exterior HVAC units serving as a means of air release rather than intake.

B. Poor indoor air quality can lead to more severe health effects like: Conjunctival (eye) irritation. Rashes. Fever, Chills.

C. The V in HVAC, or ventilation, is the process of replacing or exchanging air within a space. This provides a better quality of air indoors and involves the removal of moisture, smoke, odors, heat, dust, airborne bacteria, carbon dioxide, and other gases as well as temperature control and oxygen replenishment.

amcat

Am-Cat Restoration Rough In-Electrical Certification

Rough Electrical trades may hone their skills in a wide range of electrical techniques, all electricians s are Am-Cat certified.

1 / 10

Q. Can I sign off on electrical work without being registered?

A. Your best bet is to commission your own electrician (NICEIC recommended) and pay them to carry out a full EICR for you. If the installation is found to be unsatisfactory then you can re-negotiate on the asking price with the seller and get the works sorted out properly once you move in.

B. These are the main electrical jobs that you'll be allowed to undertake yourself. So, you might want to change and/or move sockets, ceiling lights or light switches. You can even look to change any wires that might look old or damaged.

C. If the work takes place without being signed-off on either by building control or a registered electrician, you will have an uncertified installation, which can create problems when it comes to selling the property.

D. A 'non-qualified' person can still carry out notifiable electrical work as long as Building Control are informed – but if you fail to do this and the work is found to be unsafe, it can lead to a hefty fine.

2 / 10

Q. How do I prepare for an electrical rough inspection?

A. Ask the inspector first.

B. Don't add any devices.

C. Tie your grounds together.

D. Fire block.

E. Plug holes in boxes.

F. Use correct breaker.

G. Don't power the circuit.

H. Cover the wires with wire nuts.

I. All The Above.

3 / 10

Q. What is electrical rough-in inspection?

A. At this point, all the walls are closed in, painting is finished, floors are complete, and you are ready to install the furniture. Be sure that all the circuits are functioning, and every light fixture has been hung and is connected.

B. Major remodeling work to a kitchen or bathroom also requires permits and electrical inspections. The first is called the rough-in inspection. This takes place when you have installed all of the electrical boxes, cables, conduit, and wires to the point that you are ready for the walls to be closed up by surfaces.

C. The goal of the Electrical Inspection Bureau is to enforce the safe installation of electrical wiring and equipment and to avoid the danger of electrical shock and fire.

D. An electrical safety check takes approximately two hours to complete, depending on the size of your property. If urgent repairs are required, then the check may take longer.

4 / 10

Q. Can you run two wires in conduit?

A. For two 12/2 NM cable, you need at least 1" conduit (by calculations below) but it'll still be a difficult pull. For two 12/2 UF, you'll need at least 1-1/4" conduit.

B. The maximum number of 12-gauge THHN conductors for a 3/4-inch EMT conduit is nine. The answer would be different for another type of conduit (for example, ENT), or if the conductor had a different insulation type or different outside diameter.

C. Run two more wires up the conduit - two for LINE, two for LOAD. Tape them creatively to distinguish them. The simple answer to your question is yes according to NEC Article 334.15 (B), but it may be a little more complicated than that. First the conductors must be rated for wet location.

D. When using any non metallic wire outdoor, including Romex, it is a good idea to run it through a conduit. Yes, they can be used outdoors, it is better to be safe than sorry. We recommend using a conduit when running the wire underground.

5 / 10

Q. Can you run solid wire in conduit?

A. Anything in EMT/conduit is stranded but most other work is solid wire. I do however, like to use ideal pigtails for most connections as they are 12ga stranded copper with a forked connector so the connections can be pushed into the back of the box and there is less stress on the device.

B No, you cannot run your Romex wiring in conduits.

C. The most significant difference between stranded and solid cable is performance. Because higher gauge conductors (thinner) have more insertion loss than lower gauge (thicker) conductors, stranded cables exhibit 20 to 50% more attenuation than solid copper conductors (20% for 24 AWG and 50% for 26 AWG).

D. The most common type of cable used in home wiring is non-metallic (NM), or Romex, cable. While NM cable can be run inside a conduit, this is seldom done. The types of wire most commonly installed inside of conduit are THHN and THWN. THHN/THWN wires are individual, insulated, and color-coded wires.

6 / 10

Q. What type of wire can I run in conduit?

A. Romex cannot be used in the situation you describe as buried conduit is considered a wet location. You must use conductors such as THWN. Also, minimum burial depth for conduit (PVC I assume) is 18", unless you run rigid or IMC, in which case you can go a minimum of 6".

B. Wiring used with conduit, the most common type of cable used in home wiring is non-metallic (NM), or Romex, cable. While NM cable can be run inside a conduit, this is seldom done. The types of wire most commonly installed inside of conduit are THHN and THWN.

C. You can run type NM cable in conduit, as long as the conduit is sized appropriately, and is not in a wet or damp location. If you remove the sheath from the conductors inside NM cable, you cannot use the conductors for anything (anything electrical anyway).

D. No, you can not run your Romex wiring in conduits.

7 / 10

Q. How do you rough in electrical wires?

A. Mark the box locations. Measure and mark the center of each box.

B. Place the box on the framing member.

C. Drill into corners at an angle.

D. Thread the cable through the holes.

E. Run the cable around corners.

F. Knock out a hole in the box.

G. Cut and strip the wires.

H. Push the wires into the box.

I. All The Above.

8 / 10

Q. What is included in electrical rough in?

A. The HVAC rough in period refers to when the HVAC ductwork has been installed, yet no plumbing, electrical, or exterior walls have been put into place. This is so that inspectors can have a much easier time coming in and going over each aspect of the ductwork, making sure that it is not contaminated and is fit for use.

B. Electrical rough-in, this includes laying out lines, mounting junction boxes, pulling wiring, and setting up the electrical panel, grounding, and overhead service wire. This wiring is not connected to any devices, outlets, or switches during the rough-in.

C. Rough plumbing, commonly called the "rough-in" stage, generally consists of routing pipes through wall cavities, running vent stacks to the roof, and connecting drain lines and water supply lines to sewer systems, septic systems, or main water supply valves.

D. Framing, also known as rough carpentry, is what construction companies use to give a building structure support and shape. It consists of fitting together pieces of materials, such as wood, brick, concrete, and steel. Wood is the material most often used to frame houses.

9 / 10

Q. Can you strip Romex and run-in conduit?

A. Romex is used for a purpose not to be use for something else.

B. No, that is not smart if you do not know the gage of the wire.

C. The application of Romex wires is limitless, but you actually can strip Romex and use it in a conduit outdoors. The answer is a resounding

D. When taking the wire out of Romex the wire becomes compromised.

10 / 10

Q. Do electrical wires need to be in conduit?

A. Copper is naturally corrosion resistant to most soils and underground environments. Wrapping or sleeving the copper tube in an effort to provide an additional layer of protection, while well intended, can lead to failure due to improper sleeving or wrapping practices.

B. There are no wires in conduit, and they must be installed or pulled through the conduit after installation. Rigid conduit is used for very large wires, exterior installations and where structural strength is required. EMT is the most common conduit used in residential wiring.

C. Conduit protects both humans and the electrical wiring to prevent wires from pulling loose and creating shock hazards. It's important to use conduit even for buried wires to prevent damage to wiring from digging and moisture.

D. Copper pipes are durable. They resist snapping and bacteria growth. One of the main strengths of copper is that it won't degrade in UV light. Unlike plastic pipes which are only for indoor use, copper pipes can be used in areas exposed to natural light.

Rough Plumbing trades mens may hone their skills in a wide range of plumbing techniques, all Plumbers are Am-Cat certified.

1 / 10

Q. What is a rough-in size for toilet?

A. Some older sinks may have drains that connect to a 1 1/4-inch tailpiece, but most modern drains have a 1 1/2-inch outlet. All the pipes that connect to the tailpiece, including the P-trap assembly and all the horizontal extensions, are either 1 1/4 or 1 1/2 inches in diameter.

B. The standard rough-in is 12 inches, though you may encounter 10-inch and 14-inch rough-ins in older homes. You should find the rough-in measurement in the new toilet's product information.

C. To know about the bathroom sink plumbing rough in heights you must understand that sink drain lines should be between 18 to 20 inches. The water supply pipes must be some inches higher and it should be 20 to 22 inches from the bathroom or kitchen floor and it is generally installed to the drain line sides.

D. The proper kitchen sink drain rough in height is 20 to 24 inches.

2 / 10

Q. What is a plumbing rough-in inspection?

A. Rough-in is the stage of a construction project when the various mechanical, electrical, and plumbing lines are brought in. Once the framing is up, the rough-in stage of construction begins. This is when lines are laid out, but final connections are not made until other stages of the project are completed.

B. A plumbing rough-in means that all water supply and drainpipes have been run through bored holes in the studs and other framing members and that all pipe connections have been made. A rough-in plumbing installation will need to be pressure-tested before it is deemed complete.

C. The HVAC rough in period refers to when the HVAC ductwork has been installed, yet no plumbing, electrical, or exterior walls have been put into place. This is so that inspectors can have a much easier time coming in and going over each aspect of the ductwork, making sure that it is not contaminated and is fit for use.

D. Rough-in inspection is the stage of a building project in which different mechanical, electrical, and plumbing works are checked. Once the framing is complete, the rough construction stage starts. This is when lines are drawn up, but final connections are made after other project phases have been completed.

3 / 10

Q. What is code for a shower drain

A. While a shower usually requires a 2-inch drainpipe, the vent pipe must be either 1 1/2 inches or 2 inches depending on local requirements. Be sure to double check this to see what the code is in your area.

B. The drain hole should be a minimum of twelve inches away from the wall and 9 inches in scope. Too rough in the drain, use a 1.5-inch pipe.

C. The water supply line runs out of the wall into a hole in the back of the vanity, typically placed at a height of 22 to 24 inches from the finish floor. The sink drain is then situated just 4 inches inward from the water supply line.

D. This means the Drain will typically sit 3-5” away from the back wall. It is ideal to take measurements and center the drain on the wall.

4 / 10

Q. Does rough-in plumbing include valves?

A. Water valves regulate the flow and temperature in pipes and plumbing fixtures. When they are installed and operate properly, the valves control constant flow and volume. Materials used for water valves include brass, plastic, stainless steel, bronze, cast iron and galvanized pipe.

B. Yes, A device designed to control and guide the flow of water. Examples include faucets, shower heads, shutoff valves, shower valves, and drinking fountain spouts.

C. No, on your Rough-In, values aren’t needed in the rough plumbing installations consists of routing pipes through wall cavities, running vent stacks to the roof and connecting drain lines and water supply lines to sewer systems, septic systems, or main water supply valve is the only valved used. How far should a shower drain be from the wall and how far should a linear drain be from the wall?

D. Drain lines and water supply lines are connected to sewer systems, septic systems, or main water supply valves. Pipe connections are made. Excavation and laying of underground pipes that run from utility connections to a primary structure is completed.

5 / 10

Q. What does top out mean in plumbing?

A. "Top out" is a part of roughing in but in the trades "roughing in" refers to us running the pipes up from underground/floor and "top out" refers to above (top of) ground/floor to out the roof.

B. The plumbing stub-outs are the end result of the rough-in phase of plumbing a residential or commercial building. They are usually installed while the walls are still uncovered; and after the drywall work and painting is complete, a plumber comes back and hooks them up to the plumbing fixtures.

C. There are three different types of plumbing systems; sanitary drainage, stormwater drainage and potable water.

D. So to can cleanout in your PVC systems in a building drain.

6 / 10

Q. What code book do licenses plumbers use?

A. If anyone other than the owner and occupant does the plumbing or if it is a commercial property, the work must be done by an Illinois licensed plumber.

B. Each city has their codes they enforce be advised, the International Association of Plumbing and Mechanical Officials (IAPMO) has released the 2021 edition of the National Standard Plumbing Code – Illustrated (NSPC). An updated version of the 2018 NSPC, the book may be purchased via the IAPMO web store.

C. Applicants must have been employed as a licensed apprentice plumber for a minimum of 4 years and have successfully completed at least 2 years of high school or equivalent in addition to completing an approved course instruction through a college, university, or trade school.

D. After working as an apprentice for a minimum of 4 years but no more than 6 years, you may apply to take the state test for licensing. Once you pass the test, you are a licensed plumber in the state of Illinois.

7 / 10

Q. How close does rough-in plumbing need to be?

A. For 4-inch PVC piping and a building sewer less than 50 feet long, the minimum slope is 1 inch in 8 feet, or 1/8-inch per foot, and the maximum is 1/4-inch per foot. For sewers longer than 50 feet, the slope should be 1/4-inch per foot

B. It should be between 10 and 14” from the floor. You will need to connect this discharge hole to the drainpipe with a sanitary tee. You can then move on to connect water supply lines to the shower valve or bathtub faucet. Imagine that there is an imaginary line running in the middle of the new fixture.

C. It is dependent upon gravity to function, so all waste pipes must slope downward, away from the fixtures and toward the sewer or septic tank, dropping at a rate of at least 1/4 inch per horizontal foot.

D. All of your drain pipe (with one exception) must slope slightly downhill. Usually 1/8" per foot is plenty for drainage, this is the same as the commonly recommended 1% slope.

8 / 10

Q. What comes after rough plumbing?

A. A 3-stage system might have “low”, “medium”, and “high”.) Like a hair dryer or a ceiling fan, they have some granularity to their output. Multistage systems are more common in larger and newer homes, and are often found in regions with very cold or very hot weather.

B. After the rough-in plumbing phase, once inspection passes, the remaining parts of the plumbing system (or finish plumbing) can be completed later in the construction process.

C. Three-phase power is a three-wire ac power circuit with each phase ac signal 120 electrical degrees apart. Residential homes are usually served by a single-phase power supply, while commercial and industrial facilities usually use a three-phase supply.

D. Drawing this is how I start, Blocking in, do all my corners, Adding color, Adding layers, Finished painting.

9 / 10

Q. What are the three stages of plumbing?

A. Underground rough-in phase.

B. Above ground rough-in phase.

C. Finishing phase (trim-out).

D. All The Above.

10 / 10

Q. Where do you start rough-in plumbing?

A. Ductwork Installation - Your HVAC Contractor will start by running the ductwork in the attic, or if your property has a crawlspace or a basement, perhaps in the floor joists.

B. In homes with slab foundations, the rough-in occurs before contractors pour in the slab. Typically, waste lines go in first because the pipes that take wastewater from the building are larger than supply lines. After installing the waste lines, the plumbers will then lay in the water supply piping.

C. Rough-in is the stage of a construction project when the various mechanical, electrical, and plumbing lines are brought in. Once the framing is up, the rough-in stage of construction begins. This is when lines are laid out, but final connections are not made until other stages of the project are completed.

D. In a general sense, rough-in refers to the stage of construction after the basic framing is complete and the initial services (such as wiring or pipes) have been installed, but their end-points (such as outlets or fixtures) have not been installed.

Our Partnership with Telestyles networks provides their skills in a wide range of non voltages techniques, Telestyles certified.

1 / 22

Q. What can I run with my smart home structural system.

A. You can integrate most (if not all) of your smart home devices with your voice assistant, and then control them with your voice instead of a touch screen interface, by saying things like “turn the bedroom lights on”, “set the thermostat to 75”, and “lock all the doors.

B. You can mix and match throughout your entire home, fitting each individual light with the most appropriate smart light option.

C. Automation systems can raise the value of your home by up to 5%. Others report that it can be up to 35%. Smart homes can make your life easier and save you money.

D. These smart home devices allow you to control things like wifi, door locks, security cameras, video doorbells, smart lights, appliances, heating and cooling and other systems in your home. You've probably heard a lot about home automation systems (aka smart home systems).

E. All The Above.

2 / 22

Q. What is the difference between Wi-Fi 5 and Wi-Fi 6?

A. Wi-Fi 6 devices are backward compatible with previous generations of Wi-Fi. You can get a phone with Wi-Fi 6 and connect it to your Wi-Fi 5 or Wi-Fi 4 router. You can get a router with Wi-Fi 6 and connect your older Wi-Fi devices to it, too.

B. As Intel put it, "Wi-Fi 6 is capable of a maximum throughput of 9.6 Gbps across multiple channels, compared to 3.5 Gbps on Wi-Fi 5." In theory, a Wi-Fi 6 capable router could hit speeds over 250% faster than current Wi-Fi 5 devices.

C. 2.4 GHz is not as impacted by walls, and as such was able to maintain the same transfer rate, even though it was still quite a bit slower. So the results are clear. Wi-Fi 6 can offer a significantly higher level of throughput than Wi-Fi 5, but in order to do so, it needs a strong signal.

D. Wi-Fi, often referred to as WiFi, wifi, wi-fi or wi fi, is often thought to be short for Wireless Fidelity but there is no such thing. The term was created by a marketing firm because the wireless industry was looking for a user-friendly name to refer to some not so user-friendly technology known as IEEE 802.11.

Q. What are the three types of cables?

A. The most common sizes you'll find in residential work are 14-gauge and 12-gauge. Larger appliances such as electric stoves, electric water heaters, electric dryers and central air units will often use 10-, 8- or even 6-gauge wire.

B. Fiber optic cable, twisted pair cable, and coaxial cable are the three main types of network cables used in communication systems. Each of them is different and suitable for various applications.

C. Types of Wiring; triplex wires, main feeder wires, panel feed wires, non-metallic sheathed wires and Single strand wires.

D. Ethernet cables come with RJ45 connectors on both ends. Because of this, an Ethernet cable is sometimes designated as an RJ45 cable. These cables are often used to connect computers onto Ethernet networks.

4 / 22

Q. Which wires are used in RJ45?

A. Cat6 ethernet cables will have 8 copper wires inside them. They have 4 pairs of 2 copper wires surrounded in insulation material. The copper conductors are also twisted together for better performance against crosstalk.

B. Ethernet Cat 5 cables have eight wires (four pairs), but under 10BaseT and 100BaseT standards (10 Mbps and 100 Mbps, respectively) only four (two pairs) of these wires are actually used.

C. A Category 7 cable (CAT 7) is used for the cabling infrastructure of Gigabit Ethernet with performance of up to 600MHz. Put simply, a CAT 7 cable is what we recommend you use when wiring your smart home.

D. The RJ45 data cables we use to connect computers to an ethernet switch is straight-through cables. As noted above, the RJ45 cable uses only two pairs of wires: Orange (pins 1 & 2) and green (pins 3 & 6). Pins 4, 5 (blue) and 7, 8 (brown) are NOT used.

5 / 22

Q. What are the two wiring standards for RJ45 wiring?

A. Cat5, Cat6, and Cat7 cables are the most common RJ45 cables used in today's network connection.

B. If you are looking at wiring RJ45 data jacks and plugs, there are presently two wiring standards that are almost unanimously accepted. These two standards are the T568A and the T568B. There are subtle differences between T568A and T568B, but this doesn't mean they shouldn't be addressed.

C. The RJ45 data cables we use to connect computers to a Ethernet switch is straight-through cables. As noted above, the RJ45 cable uses only 2-pairs of wires: Orange (pins 1 & 2) and Green (pins 3 & 6). Pins 4, 5 (Blue) and 7, 8 (Brown) are NOT used.

D. working with only 4 wire stranded cable isn't capable of gigabit ethernet (no surprise there). In fact, it can't even do fast ethernet.

6 / 22

Q. Do you need Cat6 for WIFI 6?

A. The right cable for Wi-Fi 6? Category 6A cables, especially those from Hitachi Cable America, are designed to support up to 10 Gigabit Ethernet, making them perfect for Wi-Fi 6. In fact, BICSI recommends installing 2 Category 6A cables per Wi-Fi access point.

B. Does WiFi 6 require new hardware? It's important to note that WiFi 6 relies on hardware updates rather than software updates, so new hardware is needed in order to see any boost in performance.

C. As technology continue to advance toward its maximum theoretical throughput of 10 Gb/s, each Wi-Fi access point is expected to require a minimum of two Cat 6A connections. It's not just speed you'll need to worry about.

D. 5g with Mm-Wave technology doesn't penetrate walls, most building materials, such as cement and brick, attenuate and reflect very high-frequency signals with a big enough loss you're unlikely to receive a very useful signal moving from inside to outside.

7 / 22

Q. What is a telecom room?

A. Telecommunications closet means a room for housing telecommunications equipment, cable terminations, and cross- connect wiring that serve that particular floor.

B. An equipment room is considered distinct from a telecommunications room because it is considered to be a building or campus serving (as opposed to floor serving) facility and because of the nature or complexity of the equipment that it contains.

C. A telecommunications room consolidates all connectivity from the enterprise network and building control systems and distributes it to pre-determined areas of the enterprise. It is the “horizontal” convergence point between the building's network backbone and workstations and conference rooms, or your utility room in homes.

D. In telecommunication, a telecommunications service is a service provided by a telecommunications provider, or a specified set of user-information transfer capabilities provided to a group of users by a telecommunications system.

8 / 22

Q. What are the types of cables, cables are classified into types depending upon their purpose ?

B. Shielded cables.

C. Twisted pair cables.

D. Coaxial cables.

E. Fiber optics cable.

F. All The Above.

9 / 22

Q. Is RJ45 the same as CAT5?

A. Although Cat5e does support Gigabit Ethernet (1000Mbps) over short distances it's a good idea to use Cat6 instead as this is designed to carry more data and you're less likely to get any issues with it.

B. All of the smart TVs currently accept an Ethernet cable at the back of the TV, while most also support wireless connection. To connect to the internet, you will need to set up a home network, and the process is very similar to connecting a laptop.

C. The difference between RJ45 and CAT5 is that RJ45 means electrical interconnection standards that is a connector whereas CAT5 is a standard related to the ethernet cables. CAT5 is easily replaceable, which makes managing them more manageable. In contrast, replacing RJ45 is difficult.

D. An Ethernet connection is generally faster than a WiFi connection and provides greater reliability and security.

10 / 22

Q. Do I need Cat5 or Cat6?

A. Cat 7 cables aren't officially supported by any home networking equipment manufacturer so they will be operating as Cat 6 cables due to backwards compatibility. You might as well get a Cat 6 cable.

B. If you want faster internet speeds, Cat6 is a good choice. It reduces something called “crosstalk” — signal transfers that disrupt your communication channels. If you are happy with your current internet speeds, however, Cat5 might be all you need. Besides, Cat5 cables tend to be cheaper than Cat6.

C. Remember, Cat5 has long been the “gold standard” of Ethernet cables and still does the job. If you are happy with your current internet speeds or have moved your server to the cloud, this type of cable is great. Cat6, on the other hand, provides you with enhanced performance and reduces crosstalk.

D. If we are talking about HDBaseT, then yes Cat5E (minimum), will support 4k video signal. To be more specific, 4k/UHD@30 YCbCr 4:4:4 8bpc, or 4k/UHD@60 YCbCr 4:2:0 8bpc. It will support HDR (HDR10 or HLG) and Dolby Vision

11 / 22

Q. What is a structured wiring package?

A. Structured wiring is a general term that refers to a whole-house network of audio, video, data, telephone, television, home automation or security signals. Wiring plan consists of coaxial cables, several fiber optics cables, and lots of Ethernet cables (Cat5e, Cat6, etc). Structured wiring can be run to every room in a home and terminated with a variety of specialized wall plates and ports for easy plug and play connection to the home network.

B. A structured wiring media panel has several functions. They terminate and distribute signals from service providers (telephone, DSL, CATV, cable modems, wireless devices, etc.) and provide a single, secure location for smart home control modules.

C. Structured wiring is not only organized but also has growth in mind because it can support high bandwidth. It allows you to upgrade your telecommunication system without a major overhaul. Installing a structured wiring system is also cost-effective because it makes changes, additions, and moves easier

D. If you're building a new home, seriously consider having smart wiring installed. Many people mistakenly believe smart wiring is a cable system, like cable TV. In fact, it's a wiring system you can use to integrate all the smart technology you use in your home. Smart wiring can be surprisingly inexpensive.

12 / 22

15 / 22

Q. How many wires does USB-C have?

A. Positive - The wire for the positive current is red. Negative - The wire for the negative current is black.

B. The meanings of these USB wire color code are: Red: The wire in red is used to pass positively charged electric power. It has 5V direct current electricity. Black: The wire in black is the ground wire. White: The wire in white is used for positive data (D+).

C. The Type-C connector was designed to enhance smaller device design and is physically smaller than previous USB connectors; openings are approximately 8.4mm by 2.6mm. This connector has come a long way from its ancestor with four wires.

D. A pink switch would be positive when the circuit is closed. White or gray neutral conductors are used in the commercial sector.

16 / 22

Q. What are the 4 wires in a USB cable?

A. The red wire is a positive power wire with 5 volts of DC power, the black wire is the ground wire (similar to most all electronic devices), the white wire is a "positive" data wire, and the green wire is a "negative" data wire.

B. 4 different USB wire colors: white and green, which carry data, and red and black, which are used for power. Red carries 5 volts and acts as the positive wire, while black is the negative wire, otherwise known as the ground wire.

C. USB cable has four conductors, two for power and two for data. The data wires are 28 AWG, the power wires are 20 to 28 AWG. The power cores are un-twisted, and the data lines twisted. Longer cables will use 20 AWG for power.

D. All The Above.

17 / 22

Q. Can I extend a USB cable with Cat5?

A. A simple way of extending USB is by using extension cables. USB extension cables are useful for extending devices over shorter distances and typically max out at around 3m in length. An alternative to standard 'passive' USB extension cables is a USB Active Extension cable.

B. One option would be to get a USB over Cat5 extender. These devices use Cat5e or Cat6 cable to extend your USB devices to distances of around 50 to 60 meters (around 150 to 200 feet).

C. Due to its design, USB cable has a normal maximum length of about 5 meters (16.4 feet), but you can get longer distances by using an active USB extension cable from Monoprice!

D. Due to its design, USB cable has a normal maximum length of about 5 meters (16.4 feet), but you can get longer distances by using an active USB extension cable from Monoprice!

Am-Cat Restoration Insulation Certification

Insulation Technicians may hone their skills in a wide range of techniques, all technicians are Am-Cat certified.

1 / 10

Q. What is the best way to insulate a crawl space?

A. Crawl space insulation, as a part of overall home air sealing and insulation, helps maintain your entire home's energy efficiency. Without insulation, heat and cool air are easily lost through the floor. Insulation also helps to preserve the air quality and reduce energy costs.

B. Foam based insulation as the best insulation for crawl spaces because it creates an air barrier. This means spray foam is the best floor insulation, so you won't need to wear extra pairs of socks.

C. Install the insulation with the paper vapor barrier facing up toward the heated living space, and make sure the insulation fits tightly between the joists. Hold the insulation in place from below using insulation support wires, or by stapling chicken wire to the bottom of the joists.

D. Crawl spaces should have their floors uninsulated, ground fog and air sealed, walls insulated and air-conditioned with indoor air. You may find no insulation at all if your home is built before 1990. The U.S. Dept. of Energy currently suggests insulation with an R-value of at least R-9 in floors.

2 / 10

Q. Is it worth it to insulate roof?

A. Give or take, about 25% of the heat produced by your boiler will escape through the roof of your home. About 35% of the heat will escape through the walls and through gaps, in and around windows and doors, and about 10% of heat will disappear through the floor.

B. Installing attic insulation this winter is a worthwhile long-term investment because it can significantly decrease your heating bills. As an added benefit, when the hot D.C. temperatures come back, the attic insulation will also minimize your air conditioning bills.

C. Rolls of foam insulation are cheap, says Brennand, and three rolls of 8in deep foam should be enough to give most lofts an important layer of protection. Mineral wool (such as Rockwool or Rocksil), glass fibre and recycled paper products all work well, according to the NEF.

D. An uninsulated flat roof has a U-Value of around 1.5 W/m2K. When insulating one, you're aiming for a value of 0.25 W/m2K or less. To achieve this, you should insulate your flat roof with insulation boards totalling around 150mm thickness.

3 / 10

Q. What is the best way to insulate under a wooden floor?

A. The majority of heat loss occurs through the roof. However, some 10 to 20 percent of heat loss is due to your floor. We do not take it into account the draughts coming up through the floor. So, if you are wondering is it worth insulating under floorboards.

B. Fibrous insulation such as mineral wool or sheep's wool performs best between timber because it will take up thermal movement and cut down air movement around the insulation. 'Thermal bypass' affects performance, so cutting out draughts is preferable.

C. A layer of dense foam padding under the laminate can help warm up the floor. In slab situations, raising the subfloor off the concrete with a layer of plywood over sleeper strips before installing the surface flooring can also make it warmer on the feet.

D. You only need to insulate the ground floor. If you're on an upper floor, you don't usually need to insulate your floor space. However, you should consider insulating any floors that are above unheated spaces such as garages, as you could be losing a lot of heat through those.

4 / 10

Q. How do you insulate a finished floor?

A. Use Weather Strips, weather strips are an inexpensive way to seal doors and windows in your home, install New Door Sweeps, apply Foam Tape, insulate with Window Film, hang Insulated Curtains, re-Caulk Windows and Doors, use a door snake.

B. Repair, replace or add new weatherstripping, get a window draft stopper, Cover cracks with nail polish, Wrap the windows with film, reglaze the windowpanes, use interior storm windows or inserts.

C. When installing insulation on top of the concrete floor, the most common method of installation is as follows. Lay the damp proof membrane onto the concrete, followed by the insulation. Then lay moisture-resistant chipboard, or a concrete screed to the top, which can then be covered by the flooring to finish.

D. Cover Floor with Vapor Barrier. Cover the entire floor with a vapor barrier, such as 6 mm polyethylene sheeting, measure and Create Furring Strips, measure 16 inches from the face of one wall, cut the Insulation, cut rigid foam insulation to fit snugly between each sleeper, cover the Insulation.

5 / 10

Q. How do you insulate windows with insulation?

A. Use window insulation films, window film creates an insulating barrier between the interior of your apartment and your windows.

B. Cover your windows with bubble wrap.

C. Install removable magnetic window insulation.

D. Use rope caulk to seal cracks.

E. Add thermal curtains to your windows.

F. All The Above.

6 / 10

Q. What insulation do you put around windows?

A. The most common types of materials used for loose-fill insulation include cellulose, fiberglass, and mineral (rock or slag) wool. All of these materials are produced using recycled waste materials. Cellulose is primarily made from recycled newsprint. Most fiberglass products contain 40% to 60% recycled glass.

B. Thermograms of mechanical systems can detect the heat created by excessive friction. Energy assessors use thermography as a tool to help detect heat losses and air leakage in building envelopes. Infrared scanning allows energy assessors to check the effectiveness of insulation in a building's construction.

C. The interior ceilings, walls and floors in your home should feel warm and dry. When drywall and paneling inside a home feels damp or cold, there is not enough insulation. Alternatively, when touching an exterior wall, it should feel cold because insulation is keeping warm air inside a home.

D. Unless damaged, insulation can last 80 to 100 years in most houses before it needs to be replaced. However, insulation can start falling from fiberglass batts after 15 to 20 years, so if your insulation was installed in batts well over a decade ago, it might be time for an inspection or a home energy audit.

7 / 10

Q. How do I know if my house is not insulated?

A. 14-15° - If your home is this cold, you may be diminishing your resistance to respiratory diseases. 18° is the recommended nighttime bedroom temperature. 19-21° is the recommended daytime temperature range for occupied rooms.

8 / 10

Q. What happens if you don't have insulation?

A. Insulation helps regulate the temperature in your home. When you don't have sufficient insulation, there's nothing to keep your heated or cooled air inside where it belongs. As a result, you and your family are always uncomfortable, either too cold in the winter or too hot in the summer.

B. It's essential to have insulation on the interior walls of your home to have effective temperature regulation. A lack of insulation can lead to extreme temperatures during the hot and cold months of the year and issues with moisture, plumbing, and electrical appliances.

C. The idea of insulation is based on energy efficiency. A home without insulation will suffer from poor thermal performance, thereby increasing utility bills and placing a strain on HVAC systems, household budgets, and the environment.

D. The roof and windows are the hottest, showing that most heat is lost from the house through those parts. Heat energy is transferred from homes by conduction through the walls, floor, roof and windows. It is also transferred from homes by convection.

9 / 10

Q. What are three reasons to insulate?

A. Shoreline structures are built to alter the effects of ocean waves, currents and sand movement.They are usually built to "protect" buildings that were built on a beach that is losing sand. Sometimes they are built to redirect rivers and streams. Other times they are constructed to shelter boats in calm water.

B. Three primary functions to a room Air Conditioner. First is to cool a specific area, such as a room, not an entire home. The second is to dehumidify, to remove moisture out of the air, so you're not sitting in a cold, clammy environment. The third function is to filter the air within the home.

C. Save energy. With home heating costs increasing over 40% during the last twelve years, one of the best ways to stay ahead of the curve when it comes to rising energy costs is to insulate your home, improve comfort, prevent ice dams.

D. Enhanced speed, lack of interference, increased security, and the ability to connect systems across long distances.

10 / 10

Q. Why is insulation necessary?

A A home without insulation will suffer from poor thermal performance, thereby increasing utility bills and placing a strain on HVAC systems, household budgets, and the environment.

B. rafts and pockets of colder air near the floor; The walls are colder and don't emit the usual amount of infrared radiation, so you lose heat due to your body emitting more IR than it receives; You may spend more time indoors and hence have less physical activity, so your body generates less heat.

C. Insulation will help you keep the desired temperature in your house all year round, protecting it against cold in winter and excess heat in summer. Insulation is also useful to reduce noise pollution. A well-insulated house is very energy efficient and will need very little additional heating and cooling.

Am-Cat Restoration Drywall Installer Certification

Drywall installers and Mud and Tapers and sanders trades may hone their skills in a wide range of techniques, all Installers are Am-Cat certified.

1 / 19

Q. Do you need to seal joint compound?

A. It makes a good base for paint or wallpaper but must be properly sealed because the paper covering, and the tape and joint compound used to seal seams have different porosity. Not sealing drywall with primer paint will result in splotches and irregularities in the finish paint.

B. The first coat of joint compound usually dries to create a slight depression and you need to reapply it to fill the imperfections completely. After the wall is smooth and the joint compound is dry, it is important to prepare the wall before painting over the joint compound.

C. Joint compound is used by pros to fill in holes and patch cracks before painting walls. A patch of paint will flash if you paint directly over it, because the compound will suck moisture out of it, giving it a flat, dull appearance.

D. Pipe joint compound, also known as pipe dope, is a type of sealant used with any threaded pipe to help create a seal. Consisting of a mixture of substances, including kaolin clay, vegetable oil, rosin, and ethanol, pipe joint compound serves as both a lubricant and a sealant for threaded joints.

2 / 19

Q. Can I paint directly on joint compound?

A. A majority of spackling compounds are water-resistant, making them ideal for both brick repair indoors and outdoors. It is important to clean and dry the brick surface before spackling it so that the compound can adhere properly.

B. You may see acceptable results by using self-priming wall paint. Joint compound should generally be allowed to dry for 24 hours between coats and before sanding, painting or priming. High humidity levels and warm temperatures both increase drying times, however.

C. You need a high-solids primer to prevent bleed-through and uneven coloring. You should also prime drywall before hanging wallpaper on it. The primer seals the paper and joint compound so that the wallpaper glue doesn't soak in and dry out. A primer is also useful when you're repainting a wall that has a gloss coat.

D. Joint compound is used by pros to fill in holes and patch cracks before painting walls. A patch of paint will flash if you paint directly over it, because the compound will suck moisture out of it, giving it a flat, dull appearance.

3 / 19

Q, What happens if you don't prime drywall?

A. At the far end, drywall mud, also known as joint compound, needs to dry for 24 hours between each coat and before sanding, priming, and painting. The 24-hour drying time recommendation can be applied to nearly all factors.

B. Because it has a glue-like base, drywall primer helps the paint adhere properly. If you skip priming, you’ll risk peeling paint, especially in humid conditions. Moreover, the lack of adhesion could make cleaning more difficult months after the paint has dried.

C. When it's dry, the mud will appear white and will be hard when you touch it. Scrape the edge of your knife over the area lightly to take down any ridges. Now, apply another layer of mud going out a few inches further than the first coat. This is called feathering and it will help hide the patch.

D. You need a high-solids primer to prevent bleed-through and uneven coloring. You should also prime drywall before hanging wallpaper on it. The primer seals the paper and joint compound so that the wallpaper glue doesn't soak in and dry out. A primer is also useful when you're repainting a wall that has a gloss coat.

E. B & D.

Q. How many coats of drywall mud do I need?

A. Pipe joint compound, also known as pipe dope, is a type of sealant used with any threaded pipe to help create a seal. Consisting of a mixture of substances, including kaolin clay, vegetable oil, rosin, and ethanol, pipe joint compound serves as both a lubricant and a sealant for threaded joints.

B. If your wall has distinct crevices, cracks, or textured areas, or if your brand of drywall mud isn't offering enough coverage, you may have to do a couple of additional coats of compound. However, in general, you'll need one coat to fill in the seams and three more coats after taping.

5 / 19

Q. Can you prime over damp drywall mud?

A. No, Joint compound should generally be allowed to dry for 24 hours between coats and before sanding, painting or priming. High humidity levels and warm temperatures both increase drying times, however.

B. Yes, all you have to do is skim coat over the areas. You may have to do more than one coat and sand in between and on the last coat once it is dry. If you do skim coat it and sand it, make sure you prime it first before painting. Skim coat will soak up the primer like new drywall.

C. If your wall has distinct crevices, cracks, or textured areas, or if your brand of drywall mud isn't offering enough coverage, you may have to do a couple of additional coats of compound. However, in general, you'll need one coat to fill in the seams and three more coats after taping.

D. There are workarounds to avoid taping and mudding your drywall, such as using molding, chair rails, or quarter round to cover seams in your drywall. However, these methods are typically more time-consuming and expensive than using tape and mud to finish your walls.

6 / 19

Q. Do you have to mud drywall before priming?

A. Scour the paint with a fine, 280-grit sandpaper, before you apply the drywall mud. Once the paint feels slightly rough to the touch, it will accept the fresh drywall mud.

B. Before applying your primer, take a black cloth and go over the surface to make sure no dust is left behind. A: No, after you are done hanging your drywall, you need to make sure that you mud and primer it before applying any coat of paint.

C. Drywall mud covers the seams where pieces of drywall meet. This protects your wiring and the structural supports in your wall from debris and moisture. Sealing your drywall also inhibits pest insects and rodents from invading your walls.

D. Drywall mud will stick to primer. So, if you have a slick wall surface, like satin or semi-gloss, you can use a coat of primer over top of it to create a surface for the joint compound to stick to. You can even skim coat over primer.

7 / 19

Q. How thick should drywall be for walls?

A. Drywall should definitely not touch concrete as moisture will wick (ie flow up the surface as in a candle/lamp wick) into the drywall and encourage mold growth. 3/8" should be sufficient - your prop up plan is not only appropriate, but a common technique used by drywallers.

B. Drywall is a flat panel made of gypsum plaster sandwiched in between two sheets of thick paper. It adheres to metal or wood studs using nails or screws. Sheetrock is a specific brand of drywall sheet. These terms are often used interchangeably.

C. The most common thickness of drywall used in residential interior construction is 1/2 inch. This material is recommended for walls with studs placed 16 inches on center. If the wall studs are placed 24 inches on center, a 5/8-inch drywall is recommended.

D. Use 220-grit sandpaper and sand the areas with a light and easy touch. Avoid using coarse sandpaper below 100 grit as that may damage the drywall.

8 / 19

Q. How many screws go into a sheet of drywall?

A. 20 screws are needed for attaching a 4-by-8 sheet of drywall. If it's 4-by-12, it'll take about 30 screws. When screwing drywall sheets (4-by-8) to the studs vertically, use four screws, and start at the top.

B. 18 screws are needed for attaching a 4-by-8 sheet of drywall. If it's 4-by-12, it'll take about 26 screws. When screwing drywall sheets (4-by-8) to the studs vertically, use four screws, and start at the top.

C. 38 screws are needed for attaching a 4-by-8 sheet of drywall. If it's 4-by-12, it'll take about 46 screws. When screwing drywall sheets (4-by-8) to the studs vertically, use four screws, and start at the top.

D. 28 screws are needed for attaching a 4-by-8 sheet of drywall. If it's 4-by-12, it'll take about 36 screws. When screwing drywall sheets (4-by-8) to the studs vertically, use four screws, and start at the top.

9 / 19

Q. How far should drywall be off the ceiling?

A. This is when the inside of your house starts to look like a house, with the drywall and most of the carpentry completed, expect about two months of finish work.

B. Drywall screws should be placed 12 to 16 inches apart, but the distance can vary. Place screws eight inches apart on edges and ceiling edges, and no more than 12 inches apart on the ceiling field. Screws are the most secure and efficient way to hang drywall.

C. Drywall should definitely not touch concrete as moisture will wick (ie flow up the surface as in a candle/lamp wick) into the drywall and encourage mold growth. 3/8" should be sufficient - your prop up plan is not only appropriate, but a common technique used by drywallers.

D. Always leave a 1/2-inch gap at the floor. This allows for floor and wall expansion without cracking the drywall. It also helps prevents moisture wicking if the floor floods.

10 / 19

Q. What comes first flooring or drywall?

A. When you're hanging drywall and installing new flooring, it's usually best to hang the drywall first and then save the floor for last.

B. As a rule, for commercial buildings, drywall should be installed vertically. On the other hand, for residential buildings, it's best to install drywall horizontally to increase structural shear strength.

C. Although you can install drywall by yourself, the job will be much easier if you have a helper or two, especially if you are covering the ceiling.

D. Always leave a 1/2-inch gap at the floor. This allows for floor and wall expansion without cracking the drywall. It also helps prevents moisture wicking if the floor floods.

11 / 19

Q. Do you hang drywall top to bottom?

A. Always leave a 1/2-inch gap at the floor. This allows for floor and wall expansion without cracking the drywall. It also helps prevents moisture wicking if the floor floods.

B. Although you can install drywall by yourself, the job will be much easier if you have a helper or two, especially if you are covering the ceiling.

C. As a general rule, for commercial buildings, drywall should be installed vertically. On the other hand, for residential buildings, it's best to install drywall horizontally to increase structural shear strength.

D. When hanging the drywall on the walls, always hang the top sheet first. Raise a sheet tight to the ceiling and secure it with a drywall nail at the top and bottom at each stud.

12 / 19

Q. How many screws go into a 4x8 sheet of drywall?

A. The wall length and ceiling area must be calculated and staggering or not staggering the sheetrock may impact how many panels are needed to complete the job. Purpose – The type of finished job should be considered when hanging sheetrock.

B. Although you can install drywall by yourself, the job will be much easier if you have a helper or two, especially if you are covering the ceiling.

C. Use about 28-32 drywall screws per sheet of 4-foot by 8-foot drywall installed horizontally on a wall. This total is comprised of four screws on the five middle studs and six screws on each of the two sides.

D. Always leave a 1/2-inch gap at the floor. This allows for floor and wall expansion without cracking the drywall. It also helps prevents moisture wicking if the floor floods.

13 / 19

Q. Is putting up drywall hard?

A. As a general rule, for commercial buildings, drywall should be installed vertically. On the other hand, for residential buildings, it's best to install drywall horizontally to increase structural shear strength.

B. With patience, the right tools, and a friend to help you, hanging drywall is not very difficult. Once you've learned how to hang drywall, learn how to tape, and finish the installed drywall for professional-quality results. The joint work is easier than it seems and provides very satisfying results.

C. Your drywall should end on stud or be butted up in the center with another piece of drywall. Either cut your drywall or add more studs. There is absolutely nothing wrong with 17-19" on center which sounds like about 3 studs per sheet. I have run into this with old houses.

D. The wall length and ceiling area must be calculated and staggering or not staggering the sheetrock may impact how many panels are needed to complete the job. Purpose – The type of finished job should be considered when hanging sheetrock.

14 / 19

Q. Should drywall touch the floor?

B. Drywall should never touch the floor. Allow for a 1/2-inch (1.27 cm) space between your new wall and your old flooring, so there is room for expansion of both materials without cracking the drywall.

15 / 19

Q. How is drywall attached to the wall?

A. However, during installation, be diligent about keeping that 1/8-inch space between sheets by using a guide. The blade of a drywall square is about 1/8-inch-thick and does the trick. Thin strips of wood can also be used as spacing guides.

B. On walls, use drywall nails or screws to attach drywall panels (“Sheetrock®”) to studs and top and bottom plates. Panel joints should be centered against ceiling joists or wall studs and staggered, so they don't align with adjacent joints.

C. The wall length and ceiling area must be calculated and staggering or not staggering the sheetrock may impact how many panels are needed to complete the job. Purpose – The type of finished job should be considered when hanging sheetrock.

D. Always leave a 1/2-inch gap at the floor. This allows for floor and wall expansion without cracking the drywall. It also helps prevents moisture wicking if the floor floods.

16 / 19

Q. Do you drywall ceiling or walls first?

A. Always leave a 1/2-inch gap at the floor. This allows for floor and wall expansion without cracking the drywall. It also helps prevents moisture wicking if the floor floods.

B. Your drywall should end on stud or be butted up in the center with another piece of drywall. Either cut your drywall or add more studs. There is absolutely nothing wrong with 17-19" on center which sounds like about 3 studs per sheet. I have run into this with old houses.

D. Hang drywall on the ceiling first, then the walls. Check the ceiling for bowed joists using a 4-ft. level.

17 / 19

Q. What tools are needed to put up drywall?

A. Wire strippers, insulated screwdrivers, insulated pliers, electrical tape, hacksaws, cable cutters, spanners, and a voltage tester.

B. Pipe wrench, basin wrench, adjustable wrench, faucet key, pipe Work, hacksaw, tube and plastic pipe cutters, plumber's torch, and thread sealing tape.

C. Drywall knife, a drywall knife is one of the first items that your teams should be putting together when getting ready to go out on a job, drywall lifts, jab saw, electric drywall saw, utility knife, T-square, tape measure, and a dust Mask.

D. Battery Powered/Cordless Drill. One tool that is an absolute must is a cordless drill, electrical Testers/Multimeter, reciprocating Saw, tape Measure (25-footer), step Ladder, hammer, extension Cord (50-footer), and screw Drivers.

18 / 19

Q. Should I use #6 or #8 drywall screws?

A. Butt joints have no recess, so you have to build up a layer of mud that's thin enough and wide enough to blend into the surrounding flat surface. When it comes to finishing drywall, the hardest part of the job is usually the butt joints—the joints formed where two non-tapered ends of drywall meet.

B. Drywall only, please: Don't use drywall screws for sub-floors, tile backing or other non-drywall applications. These denser materials can break the smaller #6 screw during installation. Use a #8 or larger for these jobs.

C. Always leave a 1/2-inch gap at the floor. This allows for floor and wall expansion without cracking the drywall. It also helps prevents moisture wicking if the floor floods.

D. Use 220-grit sandpaper and sand the areas with a light and easy touch. Avoid using coarse sandpaper below 100 grit as that may damage the drywall.

19 / 19

Q. What are the two types of seams between drywall sheets?

A. Lightweight joint compound weighs less than regular and offers lower shrinkage. After applying any type of joint compound, it must dry before sanding it. When sanding it, lightweight compound is easier to sand than regular. It is used for all drywall needs, including covering joints, corner beads, fasteners, and trim.

B. When installing drywall flat against a stud, there are two types of drywall joints, or seams, you can make: the butt joint or the tapered joint. In many cases, the type of joint you use is dictated by the application. But in a few instances, you may have a choice between butt and tapered joints.

C. You can use paper or mesh tape to finish the joints. Mesh tape is usually self-adhesive and can go right on the joints. For paper, you will need to apply a thin coat of mud to the joint, apply the tape, and press into place with the drywall knife.

D. Always leave a 1/2-inch gap at the floor. This allows for floor and wall expansion without cracking the drywall. It also helps prevents moisture wicking if the floor floods.

C. A block installed behind the crown molding at the junction of the ceiling and wall and nailed to the wall framing provides a solid nailing surface for crown molding.

D. Having, math skills, because carpenters use basic math skills to calculate accurate measurements when building structures, physical strength, communication, attention to detail, problem solving, dexterity, mechanical skills, and get real comfortable with measuring.

5 / 23

Q. Why is carpentry so hard?

A. Crown molding is a decorative finishing element that's normally used for capping cabinets, columns, and, most often, interior walls at the point where the wall meets the ceiling. It's only used at the top of a room, thus the term “crown” is used to describe the embellishment of a space.

B. Learning to be an Electrician is more difficult than learning to be a Plumber. A Plumber job, on the other hand, is more physically demanding. A Plumber earns less than an Electrician. An Electrician makes more money than a Plumber.

C. Carpentry can be hard heavy work as it often involves lots of lifting and serious manual labor, so yes becoming and staying a carpenter can be very hard.

Q. What is the difference between a trim carpenter and a finish carpenter?

A. Also called “finish carpenters” because their work adds the final touches to new construction and remodeling projects, trim carpenters represent the upper end of the carpenter career ladder, both skill-wise and salary-wise.

B. The job of a construction framer is to build the framing for a residential or commercial structure. As a framer, your duties are to read blueprints or architectural schematics and construct the building's framework according to the plans. You may also repair old woodwork on building frames.

C. Having, math skills, because carpenters use basic math skills to calculate accurate measurements when building structures, physical strength, communication, attention to detail, problem solving, dexterity, mechanical skills, and get real comfortable with measuring.

D. Most experts recommend putting crown molding in the centralized rooms of the house (like the kitchen, living room, family room, and dining room), however, the bedroom is also a great place to utilize it. It's a great way to increase the sophistication of your bedroom's design without adding clutter.

7 / 23

Q. Do finish carpenters install cabinets?

B. After you have nailed the crown molding to the ceiling, you may notice a gap between the ceiling and the crown moulding. You can minimize the appearance of the gap by simply squeezing in some silicone caulk between the moulding and the ceiling.

C. Here is a selection of duties that a finish carpenter might be responsible for on a job site: Building and installing cabinets, such as kitchen cabinets and under-stair cabinets. Install wainscoting, baseboards, door trim, and other final touches. Building and installing stair railings.

D. Crown molding is a decorative finishing element that's normally used for capping cabinets, columns, and, most often, interior walls at the point where the wall meets the ceiling. It's only used at the top of a room; thus, the term “crown” is used to describe the embellishment of a space.

8 / 23

Q. Does chair rail have to match baseboards?

A. One sculpted area is typically more compact and more detailed than the other end; the highest level of detail or sculpting goes on the bottom. The other part of the crown molding usually has one large curve or wave to it, and this end is the top.

B. After you have nailed the crown molding to the ceiling, you may notice a gap between the ceiling and the crown molding. You can minimize the appearance of the gap by simply squeezing in some silicone caulk between the molding and the ceiling.

C. Like many creative pursuits, interior design has guidelines, but no hard and fast rules. The typical trend is to match your chair rail and baseboard colors but playing with this trend the right way can also make a dramatic visual statement.

9 / 23

Q. What is standard height for chair rail?

A. It's true that the average chair rail height will be around 32 inches. However, they can be positioned anywhere from 24 to 72 inches from the floor, depending on the height of the walls and the proportions you're hoping to achieve.

B. It's true that the average chair rail height will be around 42 inches. However, they can be positioned anywhere from 34 to 82 inches from the floor, depending on the height of the walls and the proportions you're hoping to achieve.

C. It's true that the average chair rail height will be around 22 inches. However, they can be positioned anywhere from 14 to 62 inches from the floor, depending on the height of the walls and the proportions you're hoping to achieve.

D. It's true that the average chair rail height will be around 30 inches. However, they can be positioned anywhere from 22 to 70 inches from the floor, depending on the height of the walls and the proportions you're hoping to achieve.

10 / 23

Q. What kind of nails do you use for chair rail?

A. As for wood flooring fasteners, you'll use nails or staples. Staples are generally a cheaper choice of fastener, but 16-, 18-, or 20-gauge flooring nails or “cleats” are the choice of pros. They allow for wood flooring expansion and contraction, also providing great holding power.

B. Secure each piece with two 2-1/2-inch finishing nails in line with each other. When you're bringing two ends together in a miter joint, add extra wood glue at the joint, and complete the seam with two finishing nails into the studs. Use a nail set to recess the nail heads to achieve a smooth appearance.

C. The 16-Gauge Nailer is Versatile, carpenters use them for a wide variety of tasks including interior trim, baseboard, and crown. You can do stair risers with them, and they're a good option to nail down tongue and groove flooring like near a wall or in a closet where a flooring nailer won't work.
