Installation Guide

Set up a continuous
1
/2”
bead of wedi point sealant at
the perimeter channel and only
in areas where you
can immedi-
ately 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. Remove
pushed out sealant on inside
seam using a putty knife. Fas-
ten 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 transi-
tion.
Apply a skim coat and fi-
nally a combed through bed of
a thinset using modified thin-
set ANSI 118.4 and
1
/4” x
1
/4”
notch trowel.
Trowel the thinset on the
rear side of the Fundo again
using a
1
/4” x
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 sealing
gasket is firmly inserted in the
wedi trap. Apply some weight
equally and for at least 30 min-
utes (thinset bags).
Glue and seal the wedi
drain trap to the 2” pipe.
Mount the sealing collar to
the wedi Riolito/Riofino
underside counterpart using a
manual phillips screwdriver.
