Installation Guide

Apply continuous
1
/2” beads
of sealant between all connec-
tions of panels and install with
tightly butted seams. Excess
sealant must be spread flat with
a putty knife. All seams and fas-
tener 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
where the curb attaches. A
1
/2” x
1
/2” bed of thinset mortar is ap-
plied to the subfloor. The tightly
cut to fit curb is pressed into the
connection. Weight is applied on
and against the curb ( from out-
side) and another
