Product Overview:
Cement board is the most common building material used under tile installed on floors, walls, countertops, and backsplashes. Its purpose is to support the tile which needs a level surface to avoid cracking. That's why this material is also called a backer board or cement backer board.
Product Usage:
A cement board is used anywhere tile is installed to add strength to the supporting structure. A cement board may be applied to an existing wood floor, or installed horizontally on a wall. It can be used in exteriors or interiors and can be attached to both wood and steel studs.
Tips:
Cement board installation is very similar to that of drywall. It is important to first install a vapor barrier to the surface to which the cement board will be attached. Next, apply a thin layer of adhesive mortar to the surface you wish to install the board. Then attach the board to the stud, wall, or floor using drywall screws.
