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 temporary 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 initially 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 Building Panel
all the way into the channel of the shower base channel 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 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). 1 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 a continuous 1/2” (12.7 mm) bead 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 its ange right
into the center of 16” (406.4
mm) o.c. studs. wedi Joint
Sealant is set along the con-
nection of wall to niche.
2 Fasteners on 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 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 Fundo 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.
