Cement board (Hardiebacker, Durock, Wonderboard) is a cement and sand composite panel that provides a completely waterproof, dimensionally stable substrate for tile, stone, and other wet-area finishes. It is the industry standard tile substrate for showers, tub surrounds, and kitchen applications.
Smooth installs cement board for tile substrate applications in residential and commercial projects throughout the Boston area. Properly installed cement board — with alkali-resistant mesh tape at joints and appropriate fastening — provides a tile installation that will last for decades without the moisture failures common to improperly substrate-prepared installations.
Unaffected by water — will not swell, delaminate, or lose structural integrity when wet
Does not expand or contract with moisture changes — prevents tile cracking and grout failure
Accepted by all major tile manufacturers for wet area installations
Appropriate substrate for EIFS, stucco, and exterior tile systems
Framing checked for flatness and rigidity. Shimmed where needed.
Cement board installed with appropriate fastener type and spacing. Offsets at joints.
Alkali-resistant mesh tape embedded in thin-set at all joints.
