Schluter®-KERDI-BOARD-SN

Schluter®-KERDI-BOARD-SN is a prefabricated shower niche made of KERDI-BOARD that can be installed in both KERDI and KERDI-BOARD wall assemblies. The shower niche features a 1/2" (12.5 mm) -thick by 2" (50 mm) -wide integrated bonding flange and is available in 12" x 6" (30 x 15 cm), 12" x 12" (30 x 30 cm), 12" x 20" (30 x 51 cm), and 12" x 28" (30 x 71 cm) sizes.

Schluter®-KERDI over solid backing

1. Determine desired location and trace around the outside of the KERDI-BOARD-SN flange, making sure the lines are level and plumb. Cut and remove the wallboard such that the niche will be supported on both sides by the studs or other wall framing.

2. Insert the niche and fasten to the studs using wood or metal screws, placing the fasteners approximately 1/4" (6 mm) from the edges of the niche. Fasten all corners and limit fastener spacing to 12" (30 cm) o.c.

3. Connections between the niche and walls are made using KERDI membrane, applied with unmodified thin-set mortar (mixed to a fairly fluid consistency, yet still able to hold a notch). Apply the thin-set mortar using a 1/4" x 3/16" (6 mm x 5 mm) V-notched trowel or the Schluter(R)-KERDI-TROWEL, which features a 1/8" x 1/8" (3 mm x 3 mm) square-notched design. Apply the membrane over the wall and embed into the mortar throughout its entire surface to ensure proper adhesion. Remove any air pockets. The membrane is subsequently cut to match the niche opening.

Schluter®-KERDI-BOARD over wood or metal framing

1. Determine desired location and trace around the outside of the KERDI-BOARD-SN flange, making sure the lines are level and plumb. Cut and remove the KERDI-BOARD such that the niche will be supported on both sides by the studs or other wall framing.

2. Insert the niche and fasten to the studs using wood or metal screws and KERDI-BOARD-ZT washers, placing the fasteners along the seam between the KERDI-BOARD and the niche. Fasten all corners and limit fastener spacing to 12" (30 cm) o.c.

3. Seal the seams between the niche and walls using KERDI-BAND with unmodified thin-set mortar ensuring a 2" (50 mm) overlap in all directions.

Note: When using the prefabricated shelf, determine the desired height of the shelf and mark with a level line. Set tile up to that line on the back and sides of the niche. Butter the sides and back of the shelf with unmodified thin-set mortar and solidly embed it in the niche, resting on the previously installed tile. The shelf may be raised at the back to create a slope, or the tile may be set on a slope, to prevent water from pooling in the finished application.

The KERDI-BOARD-SN should be stored flat. In case of outdoor storage, protect the material from direct sunlight and weather exposure.
