1/4" PermaBase® BRAND Cement Board is a rigid substrate made of Portland cement, aggregate and glass mesh that provides an exceptionally hard, durable surface that is able to withstand prolonged exposure to moisture.

PermaBase offers a competitive advantage over similar products on the market with its patented EdgeTech® technology. The tapered, double-wrapped edge design allows for closer nail or screw application to the edge while helping prevent damage in transit and on the jobsite.

Applications

• 1/4" PermaBase Cement Board is used as an underlayment for ceramic tile on floors, countertops, tub decks and outdoor kitchen counters.
