1 DensShield® Tile Backer has scored a 10 – the highest level of performance for mold resistance under the ASTM D3273 test method. The score of 10 in the ASTM D3273 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. The mold resistance of DensShield Tile Backer has been validated by UL Environmental. Learn more about UL Environmental claims validation at ul.com/ecv.
No special or unique fasteners are required to fasten DensShield® Tile Backer panels in place. For wood studs: galvanized roofing nails, rust-resistant drywall screws or bugle head deck screws. Fasteners should be long enough to penetrate at least 3⁄4 (19 mm) into the wood framing members. For metal framing: a variety of rust-resistant screws can be used.
Yes. The DensShield® Tile Backer panel should be positioned next to framing with the acrylic coated (grey) side facing away from studs. Apply mortar or mastic and tile to the acrylic coated (grey) side of DensShield® Tile Backer panels. The built-in acrylic coating stops moisture penetration at the surface.
While gypsum boards are stronger in one direction, they may be installed either vertically or horizontally on both wood and steel studs. If the boards are to be used in a fire rated assembly, then use the board orientation that is stated in your specific rated assembly.
