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 integrates a moisture-resistant core and microbial barrier* with fiberglass mats and a unique heat-cured acrylic coating.

DensShield conforms to requirements of the 2009 IBC/IRC Code for tile backer in wet areas. It is the ideal ceramic tile underlayment for new construction, bathroom remodeling, pool areas, and many other high humidity or wet areas. It can also be painted or used in non-wet areas. It is available in convenient sizes, including a 5/8" Type X board (per ASTM C 1178) for use in appropriate fire-rated assemblies.

With millions of square feet installed, DensShield has a long and successful track record. Easier to handle than cement board, it cuts and installs like drywall, without special tools or fasteners. Lightweight and strong, DensShield is built for speed on the job site.

*Mold-Resistance Testing

When it comes to mold resistance, DensShield Tile Backer has scored a 10, the highest level of performance for mold resistance under the ASTM D 3273 test method. The score of 10, in the ASTM D 3273 test, indicates no mold growth in a 4-week controlled laboratory test. The mold resistance of any building product when used in actual job site conditions may not produce the same results as were achieved in the controlled, laboratory setting. No material can be considered mold proof. When properly used with good design, handling and construction practices, DensShield Tile Backer provides increased mold resistance compared to standard paper-faced wallboard products.

DensShield tile backer is listed by the GREENGUARD Environmental Institute as a microbial-resistant product. The microbial-resistant test is based on D 6329, a testing standard set by ASTM International, which develops testing guidelines and procedures for building materials, products, systems and services.
