-KERDI-LINE
Waterproofing the shower base
The KERDI-SHOWER-L/-LS trays are provided with integral waterproofing. When using a mortar bed, the shower base must be made waterproof using the
KERDI or KERDI-DS waterproofing membrane. The membranes can be installed as soon as the mortar bed can be walked upon.

, or unmodified thin-set mortar
to the shower base with a 1/4" x 3/16"
(6 mm x 5 mm) V-notched trowel or the
KERDI-TROWEL. The thin-set mortar must
be mixed to a fairly fluid consistency, but still
able to hold a notch.

Embed KERDI or KERDI-DS in the bond
coat and work the membrane onto the entire
surface to ensure full coverage and remove
air pockets. The membrane is carried to the
stainless steel bonding flange and to the
edges of the shower base.

When using KERDI-SHOWER-SC/-SR, repeat
the process to install the membrane over the
curb or ramp. Seams in the membrane are
constructed by overlapping the edges by 2"
(50 mm) or by abutting adjacent sheets and
installing KERDI-BAND centered over the
joint. Install KERDI-KERECK at all inside and
outside corners. When using KERDI-BOARD-
SC, seal the curb to the base and walls using
KERDI-KERECK and KERDI-BAND.

or unmodified thin-set mortar. The KERDI
collar must be cut and folded where the
KERDI-LINE is installed adjacent to walls.

Press the curb or ramp firmly into place.
Check the underside of the curb or ramp
to ensure that full coverage and support
is achieved. Note: When setting tile on the
curb, the surface must be sloped towards
the shower drain.
