Measure and cut awedi Building
Panels to fit the 16” (406.4 mm)
o.c. framework (wood or metal).
Notch out all panels if installed
around the perimeter of a flange
tub to integrate the flange and
achieve a plumb wall with square
and tight corners.
Attach a notched panel to the
framework with a 1/2” (12.7 mm)
bead of wedi Joint Sealant be
-
tween the notch and flange. At-
tach the panel to the framework
using wedi Washers and Screws
at a rate of 1 every 12” (304.8
mm)
along the studs. Leave a
gap of 1/8“ (30.2 mm) between
tub edge and wedi Panel bottom
end to allow for movement of the
tub. Alternatively apply a bead of
wedi Joint Sealant in between
both materials.

Apply a continuous 1/2“ (12.7 mm) bead of wedi Joint Sealant on the
top blue foam edge of the wedi Building Panel before installing the next
panel, butting tightly into the sealant. Set another wedi Washer and
Screw into the seam to create a flush transition between panels and
smooth over excess sealant. When installing a wedi side panel against
the already fixed wedi back wall, apply a continuous 1/2“ (12.7 mm)
bead of wedi Joint Sealant vertically on the back wall wedi Panel where
both panels will meet. Apply compression to the wedi Joint Sealant
when moving the wedi side panel into position before fastening it.
Finally and after all wedi Building Panels are installed a second 1/2”
(12.7 mm) bead of wedi Joint Sealant is applied over all seams and
fastener points and spread flat using a putty knife.
For shower tub/ tray projects where no flange is present to safely con-
nect and seal to a wall panel- please use wedi’s tub sealing tape on
page 66 and 67.
wedi Building Panels over Tub Wall Surround Application

The tub frame structure must
be properly supported and
load bearing.
Where fixtures are integrated
into the tub deck structure,
they should be equipped with
a stainless steel plate fixing
their position.

The wedi Building Panel is in-
stalled over the structure using
modified thinset mortar. wedi
Fasteners are additionally ap
-
plied on vertical areas (1 per sq.
ft.), no fasteners are used in hor
-
izontal areas. All seams, protru-
sions or fastener points must be
water
proofed using wedi Joint
Sealant.
The tub deck can be tiled over
immediately once the wedi
board is installed, seams and
possible fasteners and cut outs
sealed and the thinset mortar
has set up.
wedi Building Panels over Tub Deck Application and other paneling over horizontal
surfaces such as knee wall tops or bench tops in showers
Tub frame structures can
also be built completely of
Building Panels.
All wedi panels install over suitable horizontal backing surfaces, including knee wall tops, bench tops, curb tops must be installed in full thinset
mortar support and without any fasteners. Transitional seams to vertical wedi building panels must be safely sealed in between tightly installed panel
seams, as well as safely sealed over the seams. These seams are outside corners and hard to seal over applying a minimum thickness of wedi Joint
Sealant consistently. Following a primary surface seal of wedi Joint Sealant, a wedi Mesh Tape is embedded and sealed over again. The mesh acts
as a gauge to apply a consistent amount of sealant.
