side of the Fundo again using a
1/4” × 1/4” notch trowel.
Press the Fundo firmly into the
thinset bed, ensuring that the
installation is level and void
free. Ensure wedi drain‘s seal-
ing gasket is firmly inserted in
the wedi trap with no chance
that thinset could have pushed
into this connection area.

Set up a continuous 1/2” bead
of wedi Joint Sealant at the
perimeter channel and only
in areas where you can imme-
diately 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
sealant. Smooth out any pushed
out sealant on inside seam using
a putty knife. Fasten the panels
directly to the studs starting 1
ft above the base and at a rate
of 1 fastener per 1ft. One extra
fastener is set into the seam to
the next panel to crate a flush
transition.

Ap
ply continuous 1/2” beads of sealant between all connections of panel
s
and install with tightly butted seams. Excess sealant must be spread flat
with a putty knife. All seams and fastener heads in the assembly are
covered with a secondary 1/2” bead of sealant and spread flat. The
seams should be covered 3/4” to 1” on either side of seam. All fastener/
washers are covered with sealant stretching 1” over the washer edges.
wedi Niches are installed in
a cut out in the wedi wall
and attached with it‘s flange
right into the center of 16
o.c. studs. wedi sealant is set
along the connection of wall
to niche.
2 Fasteners each side of the
niche are set to create a flush
transition to the wall panels.
Another 1/2” bead of wedi
seal ant is spread over fasteners
and seams.
A continuous 1/2” bead of sealant is set into the channel and along the
vertical curb notch part. A circle of 1/2” sealant bead is set against the
wall panels (and) or the curb sides where the curb attaches. A 1/2” × 1/2”
bed of thinset mortar is applied to the subfloor and just a skimcoat on the
foam bottom part of the curb as a best practice. The tightly cut to fit curb is
pressed into the connection. Weight is applied on and against the curb (from
outside) and another 1/2” bead of sealant is applied over all curb seams and
spread flat. The seams must be covered 3/4” to 1” either side of a seam.
Curb connection notches must be cut to fit select Riolito neo
bases with perimeter thickness higher than 1 1/2“.
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”
shower pipe protrusions) are used for these applications and are
part of the wedi System complete warranty.
