Trowel the thinset on the rear side of the Fundo again using a 1/4” × 1/4” (6.4
× 6.4 mm) notch trowel. Press the Fundo rmly into the thinset bed, ensuring
that the installation is level and void free. Do not bend or apply uneven pressure
when pressing the part into thinset bed and drain trap. This may break the
unit‘s seals. Ensure wedi drain‘s sealing gasket is rmly inserted in the wedi trap
with no chance that thinset could have pushed into this connection area. This is
a tight t so you should use some water or safe plumbers grease to help. When
using plumbers grease, the gasket may retract upward so you need some tem
-
porary weight here to keep it fully inserted (thinset bag or tile box). Apply some
weight equally and leave on surface and drain area to allow the thinset to initi
-
ally cure without being disturbed (e.g. thinset bags). Do NOT step on the drain
module to push/connect to drain body or thinset. Ensure there is 100 % thinset
supporting the drain channel area over a completely at suboor.

Set up a continuous 1/2” (12.7 mm) bead of wedi Joint Sealant at the
perimeter channel and only in areas where you can immediately install
a wedi Building Panel into the fresh sealant. Push the wedi Panel all the
way into the channel of the shower base channel and its bead of seal-
ant. 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 start fastening 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.

Apply continuous 1/2” (12.7 mm) beads of sealant between all con-
nections of panels and install with tightly 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 seal
-
ant 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.
wedi Niches are installed in a
cut out in the wedi wall and
attached with it‘s ange right
into the center of 16 inch
(406.4 mm) o.c. studs. wedi
Joint Sealant is set along the
connection of wall to niche.
2 Fasteners each side of the
niche are set to create a ush
transition to the wall panels.
Another 1/2” (12.7 mm) bead
of wedi Joint Seal ant is spread
over fasteners and seams.
A continuous 1/2” (12.7 mm) bead of sealant is set into the channel and
along the vertical curb notch part. A circle of 1/2” (12.7 mm) sealant bead is
set against the wall panels (and) or the curb sides where the curb attaches.
A 1/2” × 1/2” (12.7 × 12.7 mm) bed of thinset mortar is applied to the
suboor and just a skimcoat on the foam bottom part of the curb as a best
practice. The tightly cut to t curb is pressed into the connection. Weight is
applied for a minimum of 30 minutes on and against the curb (from outside)
and another 1/2” (12.7 mm) bead of sealant is applied over all curb seams
and spread at. The seams must be covered 1” (25.4 mm) either side of a
seam.
Curb connection notches must be cut to fit select Riolito neo base
with perimeter thickness higher than 1 1/2” (38.1 mm).
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.
