Apply continuous 1/2” (12.7 mm) beads of sealant between all connec-
tions of panels and install with thigthly butted seams. Excess sealant must
be spread at with a putty knife. All seams and fastener heads in the
assembly are covered with a secondary 1/2” (12.7 mm) bead of sealant
and spread at. The seams should be covered 1” (25.4 mm) on either
side of seam. All fastener / washers are covered with sealant stretching 1”
(25.4 mm) over the washer edges.

Set up a continuous 1/2” (12.7 mm) bead of wedi Joint Sealant along
the pans channel on the outer perimeter and only in areas where you
can immediately install a building panel into the fresh sealant.
Push the wedi Panel all the way into the channel of the shower base chan-
nel and its bead of sealant. Smooth out any pushed out sealant on inside
seam
using a putty knife. Fasten the panels directly to the studs starting 1 ft.
(304.8 mm) above the base and in corners while keeping the board pushed
down into the channel, and set the fasteners at a rate of 1 fastener per 1 ft.
(304.8 mm). One extra fastener is set into the seam to the next panel to
create a ush transition. wedi requires wedi Building Panels to be installed
in all areas exposed to water and in any case no lower than 6” (152.4 mm)
above all water inlet xtures.
For the installation to properly work it is critical to waterproof all
penetrations of the wedi product such as shower valves and shower
heads using the appropriate sealing gaskets for the application. The
wedi Mixing Valve Flexi Collar and wedi Flexi Collar (for 1/2” – 3/4”
[12.7 – 19 mm] shower pipe protrusions) are used for these applica-
tions and are part of the wedi System complete warranty.

Trowel the thinset on the rear side of the Fundo again using a 1/4” ×
1/4” (6.4 × 6.4 mm) notched trowel. There are different ways to en-
sure good bond of the wedi Base to the suboor. Required is a setting
bed thickness of min. 3/16“ (4.8 mm) and max. of 5/16“ (7.9 mm)
(compressed). Applying thinset on both, wedi Base and suboor, is a
best practice recommended to achieve full surface coverage adhesion.
Another best practice is to use fast setting mortar to achieve faster
bond and adhesion. Press the wedi Fundo rmly into the thinset bed,
ensuring that the installation is level and void free. Apply some weight
equally and leave on surface and drain area to allow the thinset to
initially cure without being disturbed (e.g. thinset bags).
Set up the rubber caulking
gasket (with the bevelled side
up) around the 2” (50.8 mm)
pipe in the suboor. The rubber
gasket must be ush with the
upper end of the 2” (50.8 mm)
ABS or PVC pipe.
Do not use any lubricants.
60 minutes after initial instal-
lation of the drain with wedi
Joint Sealant tighten (squeeze)
the rubber caulking gasket
rmly with the caulking nut
(use a at headed screwdriver)
and nally insert the plastic
frame and strainer on top (wit-
hout adhesive). The frame and
strainer will be held in a grout
joint only once tiling commen-
ces. Do not tighten the gasket
prior to 60 minutes after the
threaded drain part was sealed
into the shower base.
