wedi Fundo Riolito neo Installation*
Before Installation:
 Have extra 2 × 4 blocking installed over bottom plate between studs
along to support wedi building panel to shower base transition area.
 Subfloor is stable, even and loadbearing, and meets deflection criteria
of maximum L/360 and requirements as per IRC. Wooden or concrete
structural substrates are dry and sufficiently loadbearing considering
live and dead load. Wood and Steel framing is sufficiently loadbearing,
plum and square.
 Floor drain assembly below floor is stabilized, fixed and supported in
position, and will not sink under water load.
 Only wedi products (Building Panels, Curb, Joint Sealant and Fasteners)
are used for wedi Fundo Shower System assembly.
 Installer has received instructions from wedi technical sales staff or is
informed about proper installation methods as described.
 wedi shower bases can be cut to size using a skilsaw. The Z notch
channel must be remade and cleaned from sawdust or other possible
contamination.

Cut the 2” pipe 1 1/4” below
the top of the Subfloor. Use
the oval shape cutting template
to cut subfloor using a jigsaw
to allow wedi drain trap to
be inserted and connected to
floor pipe using appropriate
ABS compatible or multipur-
pose cement glue. Please also
check cement glue compat-
ibility to floor pipe material.
The drain and trap have to be
secured to the subfloor. Drain
recess cut out must not add
deflection to subfloor. Please
be careful to use the oval
cutting template where your
shower base has it's drain po-
sition. While the template fea-
tures a straight side for easy
aligning with a wall, not all
Riolito's drains have the same
distance to wall framing.
Assemble the drain unit follow-
ing the instruction drawing.
wedi‘s Riolito neo bases can be
cut to size on all sides making
drain positions close to the wall
possible. Please do not cut into
the linear drains plastic flange
integrated into the coated
foam part of the base. Once
cut the 1/2” × 1/2” channels at
the new base perimeter must
be re-established. When cut-
ting close to the drain channel
always leave enough wedi
foam for re-making the
needed 1/2“ × 1/2“ channel.

Glue and seal the wedi drain
trap to the 2” pipe using ap-
propriate solvent cement glue
for the plastics involved. Do
not screw drain body/trap to
floor. Secure with some dabs of
wedi joint sealant under flange
instead. Mount the sealing
collar to the wedi Riolito neo
underside counterpart using
a manual phillips screwdriver.
Apply a skim coat and finally
a combed through bed of a
thinset using modified thin-
set ANSI 118.4 and 1/4” ×
1/4” notch trowel. There are
different ways to ensure good
bond of the wedi base to the
subfloor. Required is a setting
bed thickness of min. 3/16“
and max. of 5/16“ (com-
pressed). Applying thinset on
both, wedi base and subfloor,
is a best practice recommended
to achieve full surface coverage
adhesion.
