Description
DensGuard
®
Tile Backer is a substrate that, when properly installed,
provides significant water and moisture resistance
— making it excellent for
protecting both tile installations and stud cavities. DensGuard Tile Backer is
composed of a water-resistant treated core that is covered front and back
with fiberglass mats. The mats are permanently integrated with the core during
manufacturing to help prevent delamination problems that can occur with
paper-faced greenboard. On the tile side, DensGuard Tile Backer’s exclusive
heat-cured acrylic coating stops surface water and retards moisture transmission,
protecting the wall cavity.
Unlike cementitious backer boards, DensGuard Tile Backer has a built-in water
barrier. DensGuard Tile Backer is 17 lbs (7.7 kg) to 32 lbs (15 kg) lighter per
panel, depending on panel size, than cement board, which makes installation
easier. DensGuard Tile Backer provides excellent dimensional stability and
strength so it can be installed parallel or at right angles to framing in wall and
ceiling applications.
Primary Uses
DensGuard Tile Backer, with its fiberglass mat design, has been
independently
tested, as manufactured, in accordance with ASTM D 3273 and
has scored
the highest achievable rating (10 out of 10) for mold resistance. DensGuard
Tile Backer has been shown to be excellent for tile and non-tile installations
in wet and non-wet applications and in areas of high humidity. It is ideal for
interior walls, ceilings, residential and light commercial floors and countertop
applications in high moisture areas such as baths, showers, kitchens, laundries,
swimming pool areas and locker rooms.
DensGuard Tile Backer provides an excellent backer for sidewalls and ceilings
in bathtub and shower installations, where it provides an even, solid substrate
for tile. DensGuard Tile Backer may also be finished with paint or wallpaper
for non-tile areas that require superior fire and moisture resistance where
its moisture barrier and water-repelling qualities are desirable. DensGuard
Tile Backer also adds stabilizing and fire resistant qualities to countertop
installations.
1/4( (6.4 mm) and 1/2( (12.7 mm) x 4* (1220 mm) wide DensGuard Tile Backer
can be used as a substrate in floor tile applications for residential and light
commercial use as defined in the Handbook for Ceramic Tile Installation
published by the Tile Council of North America.
Limitations
Tiles should be applied on the gray coated side of DensGuard Tile Backer.
DensGuard Tile Backer should not be used in commercial saunas, steam
rooms, around fireplaces or areas where prolonged exposure to heat exceeds
125° F (52° C).
DensGuard Tile Backer panels should not be used as a shower pan base.
DensGuard Tile Backer should not be used for exterior installations.
DensGuard Tile Backer panels should not be used as a base for nailing and
mechanical fastening.
DensGuard Tile Backer should not be used in conjunction with passive solar
heat systems.
For floors, use floor grade tile, 2( x 2( (51 mm x 51 mm) or larger.
Use framing or furring when applying over concrete or masonry block.
Adhesives alone should not be used to install DensGuard Tile Backer. Nails,
screws or staples may be used alone or in combination with adhesives.
Since DensGuard Tile Backer has a built-in moisture barrier; never install
vapor retarders directly behind DensGuard Tile Backer panels. In retrofit
applications, some paints or other wall coverings may constitute a vapor
barrier; remove or effectively penetrate these coverings prior to installing
DensGuard Tile Backer panels.
DensGuard Tile Backer should not be used in shower floors.
Technical Data
DensGuard Tile Backer panels are mold-resistant, and have scored a 10, the
highest level of performance for mold resistance under the ASTM D 3273
test method.
When tested in conformance with ASTM E 96, DensGuard Tile Backer panels
achieved a perm rating of less than 1.5 (42.9 ng/Pa

) alone, 1.0 (28.6)
with dry set mortars.
In a test by an independent testing laboratory, DensGuard Tile Backer was
subjected to a shower of water at 110°F (43.3°C), 12 minutes per hour,
24 hours a day, 7 days a week for six months. The installation had no grout
between the tiles. No deterioration occurred to either the DensGuard Tile
Backer board, the framing members or the wall cavity.
DensGuard Tile Backer had passed the TCS Robinson Floor Test in both
1/4( (6.4 mm) and 1/2( (12.7 mm) x 4* (1220 mm) wide thicknesses with a
rating of light commercial.
