sheet-applied waterproofing
membrane and vapor retarder
with a uniform thickness of .012"

pre-sloped shower tray that
installs more quickly than
conventional mud-bed showers;
a thin, durable, waterproof

and its gradual pre-slope allows
for easy installation of tile.

Shower Walls
1. Use only code-approved
wall substrate suitable for
wet areas, such as D
urock ®
Cement Board, or F
iberock ®
Tile Backerboard.
2. Apply unmodified thin-set
mortar to wall substrate
using a 3/16" x 3/16"
(5 mm x 5 mm) v-notched
trowel or 1/8" x 1/8"
(3 mm x 3 mm) square or
u-notched trowel.
Tip: The mortar should be loose but
still hold ridges from your trowel.
3. Embed D
urock ™ Shower
System Waterproofing
Membrane into the mortar
using a finishing trowel,
drywall taping knife, or
similar tool to remove air
pockets and to ensure
proper adhesion.
Tip: Start from the center of the
wall and work toward the edges.
4. Overlap all adjoining
sections of the D
urock
Shower System
Waterproofing Membrane a
minimum of 2" (5 cm).
Note: Shingle-lapping of
membrane is not required,
provided that a minimum 2"
(5 cm) overlap is maintained at
all joints. Alternatively, adjoining
sections of D
urock
Shower System
Waterproofing Membrane can be
abutted and then seamed with
5" (13 cm) wide D
urock ™ Shower
System Waterproofing Band.
