Product Overview
DensShield
®
Tile Backer is designed for use as a tile substrate for walls, ceilings, floors
and countertops. DensShield is an ideal tile backer board for high moisture areas because
it has a built-in moisture barrier that stops moisture at the surface. This special coating
helps protect the tile installation and wall cavity from moisture intrusion. DensShield
panels are mold resistant, and have scored a 10, the highest level of performance for
mold resistance under the ASTM D 3273 test method.*
• Treated, water-resistant core.
• Fiberglass mats on front and back add strength.
• Grey, heat-cured acrylic coating helps protect the tile installation and wall cavity
from moisture intrusion and damage.
• The first tile backer in the industry with a built-in moisture barrier and a water-
resistant treated core.
DensShield Tile Backer is the first tile backer listed as a GREENGUARD microbial-
resistant product by a leading third-party organization, GREENGUARD Environmental
Institute. This listing means DensShield Tile Backer, which features fiberglass mats
instead of the paper facings used on the surface of traditional tile backers, resists
mold growth. The microbial-resistant test is based on ASTM Standard D 6329, a
testing standard set by ASTM International, which develops testing guidelines and
procedures for building materials, products, systems and services.
