DensShield® Tile Backer is engineered to prevent damage to the sub-floor or wall cavity if moisture seeps through grouted tile. DensShield® Tile Backer is the first backer board with a built-in moisture barrier. It is the ideal ceramic tile underlayment for new construction, bathroom remodeling, pool areas, and many other high humidity or wet areas. Easier to handle than cement board, DensShield® Tile Backer cuts and installs like drywall without special tools or fasteners. Can be painted or used in non-wet areas.
