wedi Drain Cover Assembly / Insertion
Insert cover frame into base hole (no glue / no screws). You may caulk between part and tile to create a exible grout joint. Optional Extension Collar
can be cut to height if part is needed. The caulk joint must not create a water barrier damming up the water draining through the thinset bed into the
drain from below the tile. Therefore the thinset layer must be continuous toward the drain. Use the black plastic extension collar if you need to raise the
wedi frame and cover. Cut extension collar to size and insert below the frame/cover. If not needed, the extension collar may be disposed of as it is not
necessary for the functioning of the wedi installation.

After Installation
All visible joints or seams in the installation are fully 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” (25.4 mm) on either side of the seam. The wedi Joint Sealant should be no less than 1/16” (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 sealants or systems
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 48-hours later. The test should not exceed 24 hours and nor should the water level exceed the height of the perimeter seams,
including a temporary dam which should be installed at the entry and 1/2” (12.7 mm) high, 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) as well as non-at pebble stones with tile edges
less than 2” (50.8 mm) may not be installed over the Fundo Ligno. 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 manufacturers recommendations and contact wedi with any
questions or regarding applications not covered here.
