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.
 Suboor is stable, even and loadbearing, and meets deection criteria of
maximum L/360 and requirements as per IRC. Wooden or concrete structu
-
ral substrates are dry and sufciently loadbearing considering live and dead
load. Wood and Steel framing is sufciently loadbearing, plum and square.
 Floor drain assembly below oor is stabilized, xed and supported in
position, and will not sink under water load.
 Only wedi products (Building Panels, Curb, Joint Sealant and Faste-
ners) 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.
 Follow applicable state or local plumbing codes requiring specic and
dimensioned waterproofed areas for a shower system or other wet
room installation. Requirements in this manual supersede local plum-
bing codes; they extend and are not in conict. wedi Shower Systems
or other wet room installations in which non-wedi product is also used
require specic project recommendations by wedi and may reduce the
extent and installation area of protection offered by wedi’s warranty.

Cut the 2” (50.8 mm) pipe 1
1/4” (31.8 mm) below the top
of the Suboor. Use the oval
shape cutting template where
you want to position the drain
to cut out subfloor using a
jigsaw to allow wedi drain trap
to be inserted and connected to
oor pipe using appropriate ABS
compatible or multipurpose ce
-
ment glue. Please also check ce-
ment glue compatibility to oor
pipe material. The drain and trap
have to be secured to the subf
-
loor. Drain recess cut out must
not add deection to suboor.
Assemble the drain unit
following the instruction
drawing. wedi‘s Riolito neo
bases can be cut to size on all
sides making drain positions
close to the wall possible. Ple-
ase do not cut into the linear
drains plastic ange integrated
into the coated foam part of the
base. Once cut the 1/2” × 1/2”
(12.7 × 12.7 mm) channels at
the new base perimeter must
be reestablished. When cutting
close to the drain channel al-
ways leave enough wedi foam
for re-making the needed
1/2“ × 1/2“ (12.7 × 12.7 mm)
channel.

Glue and seal the wedi drain trap
to the 2” (50.8 mm) pipe using
appropriate solvent cement glue
for the plastics involved. Do
not screw drain body/trap to
oor. Secure with some dabs of
wedi Joint Sealant under ange
instead. Mount the oval sealing
collar / gasket to the base‘s recei
-
ving ABS plastic channel on it‘s
underside with no gaps showing
in between both parts. Use only
the wedi screws provided and
manually tighten with a Phillips
screwdriver. Instead of gluing
the drain trap to the oor pipe
rst, you may also connect it to
the wedi Base‘s sealing gasket
rst to ensure a visibly tight con
-
nection. The trap will then glued
to the oor pipe later when the
base is installed to the oor.
Apply a skim coat and nally
a combed through bed of a
thinset using modied thinset
ANSI 118.4 and 1/4” × 1/4”
(6.4 × 6.4 mm) notch trowel.
There are different ways to
ensure good bond of the wedi
Base to the suboor. Requi
-
red is a setting bed thickness
of min. 3/16“
(4.8 mm) and
max. of 5/16“
(7.9 mm) (com-
pressed). Applying thinset on
both, wedi Base and suboor,
is a best practice recommen
-
ded to achieve full surface co-
verage adhesion. Another best
practice is to use fast setting
mortar to achieve faster bond
and adhesion.
