33. You can now insert the wedi Fundo Riolito Drain Cover. These stainless steel covers are available in different color finishes with
durable coatings, or as a natural polished stainless steel, or as a tileable cover. The covers are equipped with supports which
are mounted to the cover and will rest in pre-made depressions inside the linear drain channel where they support the cover.
Reference the drain cover installation manual for installation of supports, and how to adjust supports and drain covers for height
to match the tile surface (adjustment varies between models from 3/16 in. low to 1 in. high).
34. The wedi Fundo Riolito Modular Shower System is now ready for tiling as soon as the surface applied wedi joint sealant is dry
to the touch.
All fastener points are visibly covered with wedi joint sealant. All protrusions
(ie. plumbing fixtures) are sealed into the wedi assembly with wedi gaskets
and sealant. All visible joints or seams in the installation are visibly covered
and reinforced with wedi Joint Sealant that is applied flat over the seams.
Coverage of wedi Joint Sealant over all seams should be at least 1 in. (25.4
mm) on either side of the seam. wedi Joint Sealant should be no less than
1/16 in. (1.6 mm) thick to ensure strength. Do not add mesh tape into the
wedi Joint Sealant; this may put the waterproofing performance at risk,
and will not strengthen the sealant or system resistance against movement-
related stresses. Once wedi Joint Sealant has been applied over all shower
system seams, an optional water flood test may be performed in as little as
2 hours. Please ensure the sealant has cured sufficiently and has formed
a skin no longer pliable or sticky leaving sealant residue upon touch. The
sealant is a moisture curing product that will react to cure very slow when
applied in a location with low relative humidity in the air, and it will overreact
and malfunction if exposed to too much water ( e.g. flood test) too early.
The test should not exceed 24 hours, 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 testing the drain connection for a proper seal. While a full
surface flood test is not required for non-absorbing products like wedi,
it may be required by a building inspector. When tiling commences, no
premixed (“mastic”) tile adhesives may be used over wedi systems in any
wet area installation. When tiling the wedi Shower Bases, incl. extensions
or ramps, tile thickness should generally be no less than 1/8 in. (3.2 mm).
Choose setting materials appropriate for the type of stone, ceramic, or glass
tile as well as for a wet area installation. When tiling with a square size of
2 in. × 2 in. (50.8 × 50.8mm) or more, install using a polymer modified
cement based tile adhesive and grout. When tiling with a square
size of less than 2 in. × 2 in. (50.8 × 50.8 mm), install using a polymer
modified cement based tile adhesive and use a 100% solids epoxy
grout. When tiling with a square size of 1 in. × 1 in. (25.4 × 25.4 mm)
or less, install using a 100% solids epoxy tile adhesive and grout. Only
non-flat bottom pebble stone installations, including small mosaics, may be
installed using polymer modified cement based tile adhesive and grout if the
mortar fully supports the tiles rounded undersides. All flat 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) are 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 (i.e. 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 the tile can always be fully
supported by the tile adhesive setting bed, and the surface of the wedi Base.
Refer to TCNA guidelines for setting material coverage required by the tile
being installed. Use only cleaners and sealers fee of acid or solvents on tile
or grout installed over wedi product, and apply only in amounts 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.
 Where wedi Building Panel or curb overs / caps are installed over horizontal
surfaces (seats, curbs, tubdeck transitions) do not set any fasteners and do
not allow the glass door installation to penetrate the wedi panel as it is
your waterproong.
 Make sure that doors are installed tight to contain water inside the shower.
Make sure doors are installed to only load bearing reinforced framing.
Consider wedi CURB AT (Anchor Track) when planning to mount glass
door/panel xtures through the curb surface. Ensure not to anchor doors
or glass panels through the sloped shower base oor but position the door/
glass panel right at the beginning of the slope but anchored into the at
oor structure. Ensure proper waterproong of anchor points.
 Where wedi buildig panel is installed over corners of a structure showing
an angle other than 90° please miter the board edges to gain adhesion
surface. Utilize a wedi sealing tape in addition to regular sealing for safety.
