Am-cats Team Drywall/Carpentry will cost $350 per day per carpenter and each sheet will cost $10 per sheet Fastened.

Durock and Hardie-Backer not only recommend that you use thin-set under their backer board, but they specify it and will void the warranty on their product if it’s not used. Not only is thin-set a critical component underneath cement board but the other critical component is the fasteners. And you won’t have the fasteners if you are trying to install it over concrete. Doing this will require that you remove the existing surface material before installing the backer board over the studs. Cement boards can also be used on countertops when laying tile. However, the process will involve using an extra sheet of the backer board.

Am-cat never uses standard screws when installing cement boards. cement board is an ideal substrate for floor and countertop ceramic tile installations. The 1/4″ thickness helps eliminate transition trim when abutting carpet or wood flooring and minimizes level variations with other finish materials.
