FLOOR DRAINS

still able to hold a notch.
a. KERDI: Apply unmodified thin-set
mortar to the mortar bed surrounding
KERDI-LINE with a 1/4" x 3/16" (6 x
5 mm) V-notched trowel or the KERDI-
TROWEL, which features a 1/8" x 1/8"
(3 x 3 mm) square-notched design.
Embed KERDI in the bond coat with
the flat side of the trowel to ensure
full coverage and remove air pockets.
b. DITRA: Apply unmodified thin-set
mortar to the mortar bed surrounding
KERDI-LINE with a 1/4" x 3/16" (6 x
5 mm) V-notched trowel or the DITRA-
TROWEL, which features an 11/64" x
11/64" (4.5 x 4.5 mm) square-notched
design. Solidly embed the matting into
the bond coat using a float, screed
trowel, or DITRA-ROLLER.
2. Apply unmodified thin-set mortar to
the membrane surrounding KERDI-
LINE with a 1/4" x 3/16" (6 x
5 mm) V-notched trowel or the KERDI-
TROWEL, which features a 1/8" x 1/8"
(3 x 3 mm) square-notched design.
Embed the KERDI collar in the bond
coat to ensure full coverage and remove
air pockets.
Grate assembly
Grate A and B
1. Apply unmodified thin-set mortar to
the underside of the grate frame and
place it in the channel body ensuring
full coverage and support of the
frame. Insert the foam spacers in the
grate frame to reinforce it during the
remainder of the installation.
Note: The tape on the grate frame does
not need to be removed. It is intended
to help keep setting material out of the
channel body during installation.
2. Insert the plastic height adjustment
spacers with threaded bolts under the
tabs along the inside of the grate frame
to adjust the elevation of the frame
such that the surface of the frame will
be flush with the surface of the tile
covering. The spacers may be adjusted
simply by turning the bolts by hand.
3. Apply unmodified thin-set mortar to the
substrate and install the tiles, ensuring
full coverage. Once the tile covering is
set and grouted, remove the spacers
from the grate frame and insert the
grate.
Note: Protect the visible surfaces of the
grate frame and grate from contact with
setting and grouting materials. Setting
and grouting materials must be removed
immediately.
KERDI-LINE-FC
1. Install KERDI-LINE channel bodies end-
to-end and overlap the KERDI collars
using unmodified thin-set mortar to
ensure a waterproof connection.
KERDI-LINE-FC is subsequently
installed in conjunction with the KERDI-
LINE grate assembly and adjacent tiles.
Note: KERDI-LINE-FC may be used
with tiles that are 1/4" (6 mm) thick or
greater.
2. Apply a sufficient amount of thin-set
mortar to the substrate and/or the
back of KERDI-LINE-FC and press the
profile into the mortar until its surface
is flush with the adjacent tile and grate
assembly.
3. Leave a space of approximately 1/16" –
1/8" (1.5 – 3 mm).
4. Fill the joints completely with grout or
setting material.
Grate D
Wall Installation
1. Peel protective foil off the cover strip
and adhere the strip to the bonding
flange adjacent to the wall(s). Position
the strip along the edge of the channel.
The cover strip hides and protects the
KERDI surface under the tile.
2. Insert the tile spacers into the channel
body. Install the surrounding tile on
the adjoining walls and mortar bed
up to the spacers using unmodified
thin-set mortar, ensuring full coverage.
Remove all excess setting material.
3. Apply tile to the top of the covering
support using unmodified thin-set
mortar. The tile is installed flush with
the front side of the covering support
to provide the drainage opening and
overhanging the back side of the
covering support to cover the bonding
flange along the wall. Measure and cut
the tile such that an approximate 1/16"
(1 mm) gap is left at the wall. When the
ends of the channel body are located
adjacent to walls, the tile is installed
overhanging the end of the plate to
cover the bonding flange along the
walls. Measure and cut the tile such
that an approximate 1/16" (1 mm) gap
is left at the walls.
Note: When the mortar bed is tiled beyond
the ends of the channel, the tile on the ends
of the covering support can be cut to either
match the grout joints of the surrounding
floor covering or to provide a perimeter
drainage opening.
Intermediate Installation
1. When the ends of the channel body
are located adjacent to walls, peel
protective foil off the cover strip and
adhere the strip to the bonding flange
adjacent to the walls. Position the
strip along the edge of the channel.
The cover strip hides and protects the
KERDI surface under the tile. When
the mortar bed will be tiled beyond the
ends of the channel, the cover strip is
not required.
2. Insert the tile spacers into the channel
body. Install the surrounding tile on the
adjoining walls (if applicable) and mortar
bed up to the spacers using unmodified
thin-set mortar, ensuring full coverage.
Remove all excess setting material.
3. Apply tile to the top of the covering
support using thin-set mortar. The tile
is installed flush with the front and
back of the covering support to provide
the drainage openings. When the
ends of the channel body are located
adjacent to walls, the tile is installed
overhanging the end of the plate to
cover the bonding flange along the wall.
Measure and cut the tile such that an
approximate 1/16" (1 mm) gap is left at
the wall.
Note: When the mortar bed is tiled beyond
the ends of the channel, the tile on the
ends of the covering support can be cut
to either match the grout joints of the
surrounding floor covering or to provide
perimeter drainage openings.
Note: For acid-resistant coverings, use an
epoxy adhesive to set and grout the tile.
Maintenance
KERDI-DRAIN and KERDI-LINE require no
special maintenance and are resistant to
mold and fungi. The grate may be removed
to clean the drain housing and the drain
pipes.
Clean the grates and profiles using common
household cleaning agents. Stainless steel
exposed to the environment or aggressive
substances should be cleaned periodically
using a mild household cleaner. Regular
cleaning maintains the neat appearance
of stainless steel and reduces the risk of
corrosion. All cleaning agents must be free
of hydrochloric acid, hydrofluoric acid, and
chlorides. Stainless steel surfaces develop
a sheen when treated with a chrome-
polishing agent. Do not use abrasive or
alkaline cleaning agents.
