sealant application 2 in. wide on top of the seam. All seams to wedi walls must also be sealed internally with
a 1/2 in. bead of continuously applied wedi Joint Sealant between parts in that transition, and the seams are
then covered with another 1/2 in. bead of wedi Joint Sealant which is spread flat over the seam covering it 2
in. wide. Tiling may begin once thinset under wedi Subliner Dry or wedi Building Panels on floor has cured.
Note: When using wedi Building Panel to waterproof the floor and transition to the Fundo shower base you need to
still install wedi subliner Dry or wedi Building Panel made flashing up on all walls by 2 inches and waterproof/cover
seams as in the general wedi wall assembly.
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 groove between threads at the height you measured in the previous step. Please note,
the threaded connection also allows for some adjustment after cuts are made. 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 ¼ 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 assembled (see next steps).
30. Place the drain cover unit into the Drain Cover Extension were it fits into a tight seat. The cover is now vertically adjustable
and can also move horizontally to fit the tile layout.
31. The drain cover unit can still be moved laterally 3/16 in. in either direction, and can be aligned with the tile regardless of
how much height was added.
32. The wedi Fundo Primo Shower System is now ready for tiling as soon as the surface applied wedi joint sealant is dry to
the touch.
