A continuous 1/2” (12.7 mm) bead of sealant is set into the channel
and along the vertical curb notch part. A circle of 1/2” (12.7 mm) seal-
ant bead is set against the wall panels (and) or the curb sides where the
curb attaches. A 1/2” × 1/2” (12.7 × 12.7 mm) bed of thinset mortar
is applied to the suboor and a skim coat on the bottom surface of the
curb as a best practice. The tightly tting curb is pressed into the con-
nection area. Weight is applied for a minimum of 30 minutes on and
against the curb (from outside) and another 1/2” (12.7 mm) bead of
sealant is applied over all curb seams and spread at. The seams must
be covered 1” (25.4 mm) either side of a seam.
wedi Niches are installed in a cut out in the wedi wall and attached with
it‘s ange right into the center of 16” (406.4 mm) o.c. studs. wedi Joint
Sealant is set along the connection of wall to niche.
2 Fasteners each side of the niche are set to create a ush transition to
the wall panels. Another 1/2” (12.7 mm) bead of wedi Joint Sealant is
spread over fasteners and seams.
Curb connection notches must be cut to fit select Primo bases
with perimeter thickness higher than 1 1/2” (38.1 mm).
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”
[12.7 – 19 mm] shower pipe protrusions) are used for these applica-
tions and are part of the wedi System complete warranty.
After Installation
All visible joints or seams in the installation are visibly covered and reinforced with wedi Joint Sealant applied at over the seams. Coverage of wedi Joint
Sealant over all seams should be at least 1 inch (25.4 mm) on either side of the seam. The wedi Joint Sealant should be no less than 1/16 inch (1.6 mm)
thick for strength. Do not add mesh tape into the wedi Joint Sealant. This may only put the waterproong performance at risk and will not strengthen the
sealant’s or system’s resistance against movement related stresses. Once wedi Joint Sealant application over all shower system seams has been completed,
an optional water ood test may be performed as early as 2 hours later. The test should not exceed 24 hours and nor should the water level exceed the
height of the perimeter seams so that the fresh sealant may continue to a full cure without too much weight added during that process. wedi recommends
to test at least the drain connection for its proper seal while a full surface ood test is not technically required for non-absorbing products like wedi but
may be required by a building inspection department. When tiling commences, no premixed and organic (“mastic”) tile adhesives must be used over wedi
Systems in any wet area installation. When tiling the wedi Shower Bases incl. extensions or ramps, tile thickness should generally not be less than 1/8” (3.2
mm). Choose setting materials appropriate for the type of stone, ceramic or glass tile as well as for a wet area installation. Tile with a square size of 2 × 2”
(50.8 × 50.8 mm) or more may be installed using a polymer modied cement based tile adhesive and grout. Tile with a square size of less than 2 × 2” (50.8
× 50.8 mm) may be installed using a polymer modied cement based tile adhesive and require 100% solids epoxy grout. Tile with a square size of 1 × 1”
(25.4 × 25.4 mm) or less must be installed using a 100 % solids epoxy tile adhesive and grout. Only non-at bottom pebble stone installations including
in part small mosaics may be installed using polymer modied cement based tile adhesive and grout, all at bottom pebble stone installation are subject
to the general tile size based setting materials recommendation outlined above. When installing non-square tile, the length of the shortest tile edge(s) is
considered as its square size for the purpose of determining the choice of the setting materials as outlined above.
All tile installations designed to receive heavier point loads such as from wheelchair use, must be grouted using 100% solids epoxy grout. Large format tile
may be installed over wedi Fundo shower bases. Cuts may have to be made in consideration of the base’s slope lines and so that such tile can always be fully
supported by the tile adhesive setting bed and the surface of the wedi Base. Tile adhesive coverage under the tile must be 95 % and special care must be
taken to achieve good transfer of adhesive to wedi’s shower base when working with mesh backed tile. Please use only solvent and acid free cleaners and
sealers on tile and grout installed over wedi product and apply such products only in amounts as needed to treat the surface materials without drenching
the substrate. Follow setting materials manufacturer's recommendations and contact wedi with any questions or regarding applications not covered here.
