Product Brochure

21. wedi Niches are installed in a cut out in the wedi wall and attached with it‘s flange right into the center of 16 in. o.c. studs.

wedi Joint Sealant is set along the connection of wall to niche.

22. Fasteners every 12 inches on either side of the niche, or a minimum of 1 fastener on each of the 4 corners, are set to create a

flat transition to wall panels. Another 1/2 in. bead of wedi Joint Sealant is spread flat over fasteners and seams.

23. 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 in. – 3/4 in. shower pipe protrusions) are used for these applications, and are installed using a full bed of wedi

joint sealant for attachment. These sealing measures are required for wedi‘s waterproofing system warranty. Contact us for

alternative waterproofing options if fixtures do not fit wedi standard collars so we can recommend optional best practices

under wedi warranty.

24. A continuous 1/2 in. bead of sealant is set into the channel and along the vertical curb notch part. 1/2 in. beads of wedi joint

sealant are equally applied on wall surfaces where the curb attaches. A 1/4 in. square notch trowel is used to apply a thinset

mortar on the subfloor and on the wedi curb bottom (reference wedi Fundo installation in thinset mortar). The tightly fitting

curb is pressed into the connection area. wedi Lean Curbs can be installed by entirely using wedi joint sealant (replaces thinset

attachment to floor). Please note: wedi curb notches are pre-made for channel connections to wedi bases 1 1/2 in. thick at

perimeter. When using thicker perimeter bases, please cut the curb notch for a tight dry fit connection.

25. Weight is applied for a minimum of 30 minutes on and against the curb (from outside) and another 1/2 in. bead of sealant is

applied over all curb seams and spread flat. The seams must be covered 1 in. either side of a seam.

26. 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 1/4 in. low to 1 in. high).

27. 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.
