There are several grate options available for the Schluter-KERDI-LINE linear drain.
The KERDI-LINE Tileable Covering Support D is a stainless steel plate with Schluter-KERDI
waterproofing membrane laminated on the surface to allow for bonding ceramic or stone tile
which creates a virtually invisible drainage line.
Here s how to install it. The KERDI-LINE channel body has been installed
and waterproofing of the shower area is complete.
Installation of Covering Support D can now begin. Peel the protective foil from the cover strip and
adhere the strip to the bonding flange adjacent to the wall.
Position the strip along the edge of the channel. The cover strip is used to hide and protect the
Schluter-KERDI membrane under the tile when the channel body is located adjacent to vertical
surfaces, such as walls and curbs. Install the surrounding tile on the
adjacent vertical surfaces using unmodified thin-set mortar, ensuring full coverage.
Insert the tile spacers into the channel body. The spacers will be used as tile setting guides
for the remainder of the installation. Install the surrounding tile on the shower
base up to the spacers using unmodified thin-set mortar, ensuring full coverage.
Remove all excess setting material. Measure and cut the tile to be applied to
the covering support such that a 1/16 inch gap is provided at all vertical surfaces
and the tile is flush with the edge of the covering support to provide
drainage openings at all other locations. Place the covering support into the channel body.
Apply thin-set mortar to the underside of the tiles where
they will be set on the covering support. The covering support tile is installed flush
with the front side of the covering support to provide the drainage opening and overhanging
the covering support to cover the bonding flange at adjacent vertical surfaces.
When KERDI-LINE is installed at intermediate locations,
the tile is installed flush with the front and back of the covering support
to provide the drainage openings. Once the tile has set, the covering
support can be removed, grouted, and reinserted into the channel body.
The covering support can be removed for cleaning purposes using the supplied hook.
