Tile Backer
Wet Non-Tile Areas
DS012
For wet, non-tile areas, steel or wood framing should be spaced no greater than 16” (406 mm) o.c. for 1/2” (12.7 mm) DensShield
Tile Backer or 24” (610 mm) o.c. for 5/8” (15.9 mm) DensShield Tile Backer. For ceilings, boards should be spaced no greater than
12” (305 mm) o.c. for 1/2” (12.7 mm) thickness or 16” (406 mm) o.c. for 5/8” (15.9 mm) thickness.
In non-tile areas exposed to water or water condensation for prolonged periods, such as gang showers, processing plants,
clean rooms and laboratories, apply a 6” (152 mm) wide strip of Sto Reinforcing Mesh or equivalent to angles and embed with
Sto Flexyl
TM
Ground Coat or equivalent.
Skim coat the entire surface with Sto Flexyl to achieve a flat and uniform surface. Prime with Sto Primer.
Note: Results in a fine sanded texture.
Use a two part or one part water reducible epoxy coating suitable for the use intended. Coating must be applied according to
manufacturer’s instructions and meet desired water vapor transmission rate.
In all steps, apply finishing materials according to manufacturers’ instructions.
High-Humidity Non-Tile Areas
DS011
For areas exposed to continuous, higher-than-normal moisture levels, such as those found in enclosed swimming pools, garden
areas, therapy rooms, locker rooms, laboratory white rooms, operating rooms, commercial and institutional kitchens, finish
DensShield Tile Backer with materials that are highly water-resistant and form a moisture barrier in conjunction with DensShield
Tile Backer of less than 1.0 perms (57 ng/Pa•s•m
2
). For walls, steel or wood framing should be spaced no greater than 16” (406
mm) o.c. for 1/2” (12.7 mm) DensShield Tile Backer or 24” (610 mm) o.c. for 5/8” (15.9 mm) DensShield Tile Backer. For ceilings,
boards should be spaced no greater than 12” (305 mm) o.c. for 1/2” (12.7 mm) thickness or 16” (406 mm) o.c. for 5/8” (15.9 mm)
thickness. See Sto Corporation Specification No. F-477, or other manufacturers’ highly water-resistant equivalents.
Note: A finishing method must never be used in a more severe environment than described.
DS010 Dry Non-Tile, Non-Wet Areas
This installation should be used in interior non-tile areas that do not come in contact with water and may experience intermittent
exposure to high levels of humidity for short and infrequent periods of time, such as outside of tub and shower areas in residential
construction. For walls, steel 25-gauge min (.0188) or wood framing should be spaced no greater than 16” (406 mm) o.c. for 1/2”
(12.7 mm) DensShield
®
Tile Backer or 24” (610 mm) o.c. for 5/8” (15.9 mm) DensShield Tile Backer. For ceilings, boards should be
spaced no greater than 16” (406 mm) o.c. for 1/2” (12.7 mm) thickness or 24” (610 mm) o.c. for 5/8” (15.9 mm) thickness.
Joint Compound
Apply 2” (51 mm) fiberglass mesh tape over joints and
angles. Embed tape in setting com pound. Trowel all
purpose or a setting type joint compound over entire
DensShield Tile Backer panel to produce a smooth
surface. Prior to painting or papering, the surface
should always be primed with a primer suitable for
high- moisture areas, as recommended by the paint
or wallpaper manufacturer for applications over joint
compound.
