22. 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.
23. 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.
24. 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 or wedi sealant 620 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.
25. 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.
26. 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.
Several Fundo Primo models naturally feature different perimeter height or thickness at the edge. Therefore, pre-made standard notch connections of
wedi curbs must be modified in the field for a tight fit to the bases. Ramps and Extension panels can naturally not fit to all models and might be modified
in the field as well. When using curbs with shower bases and / or Fundo extensions that create a one directional slope and build up height towards one
side of the shower, you may need to increase the height of the curb to exceed the surface of the shower base as required by applicable plumbing code.
Where wedi building 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. Contact us for recommended best practices under warranty.
27. Next, insert the Drain Cover Extension into the threaded part of the Alignment Ring 1. Dry fit the Drain Cover Extension for
the needed final height position of the drain cover unit. The Drain Cover Extension only works for wedi’s finished surface
drain covers, but not with wedi’s tileable covers due to their special water drainage design. wedi Tileable covers are made
to work with defined tile thicknesses and can be inserted into the Alignment Ring 1 and Snap Ring 2 assembly directly.
28. Dry-fit a tile for the shower base right next to the extended drain cover unit and determine to what height the Drain Cover
Extension may need to be cut down for a drain cover top flush with the top of the tile (or drain cover top slightly below
top of tile). Account for the thickness of the (compressed) thinset mortar used to install the tile. Using a ruler or measuring
tape if necessary, match this measurement along the side of the Drain Extension piece.
29. The Drain Cover Extension can be cut to height/length at its threaded part using a fine tooth saw for a fast, clean and safe
process. Make a cut within one of the cutting grooves to adjust the extension to the height needed. Leave the extension
a bit longer than needed (by one cutting groove). The Drain Cover Extension should connect to the threaded Alignment
Ring safely and for good support, which requires at least one full turn of the extension‘s male threads reaching into the
Alignment Ring 1’s female threaded part. The extension can be used to increase the position of the drain cover by 1 1/4 in.
If no height adjustment or increase in height is needed for the drain cover, please cut the drain cover extension shorter at
the cutting groove closest to the squared top. This will leave enough of the tightly threaded part needed to connect into
the drain opening or Alignment Ring. This will allow you to let the wedi drain cover rest flat over the drain opening once
