Cement Board 1220mm x 2440mm

Cement board is a combination of cement and reinforcing fibers, typically used as a tile backing board. Cement board can be nailed or screwed to wood or steel studs to create a substrate for vertical tile and attached horizontally to plywood for tile floors, kitchen counters and backsplashes. It can be used on the exterior of buildings as a base for exterior plaster systems and sometimes as the finish system itself.

Cement board adds impact resistance and strength to the wall surface as compared to water resistant gypsum boards. Cement board is also fabricated in thin sheets with polymer modified cements to allow bending for curved surfaces.

In areas continually exposed to water spray (i.e. showers) a waterproofing barrier is usually recommended behind the boards or as a trowel – applied product to the face of the boards behind the finish system.

Water resistant cement board is composed of a treated gypsum core with a non organic fiber reinforced covering, either on one or both faces.

Gypsum core “cement” board panels are ideal for moist but not truly wet installations of tile and/or stone walls.
