PermaBase® Cement Board Underlayment

Description

Cement Board Underlayment for Ceramic Tile

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

PermaBase has a lower moisture absorption rate than other backerboards, which ensures an accurate open time and a better bond. Double-wrapped edges allow for closer fastening of nails or screws without crumbling or spinout. It is extremely durable in transit and on the jobsite, while also easier to handle.
