GoBoard is engineered and tested for strength and durability, yet can be cut right where it’s installed using a utility knife. Plus, it's up to 80% lighter than traditional boards. Installation time is reduced because waterproofing is built-in, eliminating extra steps since only board joints and fastener locations need to be sealed.

National Gypsum 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 is ideally suited as an underlayment or backing surface for tub and shower surrounds, countertops, flooring and a variety of other interior and exterior applications.
