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 waterproong 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 modied 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 modied 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 modied 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. 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.
