The wedi Fundo Riolito Shower System is now ready for tiling as soon as the
surface applied wedi joint sealant is dry to the touch.
El sistema de ducha wedi Fundo Riolito está ahora listo para el enlosado ni
bien la superficie aplicada con sellador de juntas wedi esté seca seco al tacto.
Le système de douche wedi Fundo Riolito peut être carrelé dès que le produit
d’étanchéité de joint wedi recouvrant les joints est sec au toucher.

EN 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-re-
lated stresses. It is recommended to add wedi mesh tape over seams featu-
ring outside corners (e.g. pony wall tops or curb deck transitions). The wedi
mesh tape is applied over finished and topically sealed seams once these are
dry to the touch. wedi joint sealant is then applied to cover the mesh. This
method allows you to apply more sealant consistently over a transition where
it is difficult to apply sufficiently thick sealant. The mesh functions here as
a thickness gauge, but has no other function. 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 × 50.8
mm) 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 free 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.
