With the available panel thicknesses of
3/16", 3/8", 1/2", 5/8", 3/4", 1", 1-1/2",
and 2" (5, 9, 12.5, 15, 19, 25, 38, and
50 mm), KERDI-BOARD covers a broad
range of application areas for creating flat,
level, plumb, square, and dimensionally stable
substrates for the installation of ceramic and
natural stone tiles. With suitable preparation
of the abutting seams and joint areas, the
panel may be used for bonded waterproofing
assemblies.
KERDI-BOARD is suitable for: creating tile
substrates on masonry walls, wood or metal
framing, and other finished wall surfaces;
creating straight or curved partition walls;
creating straight or curved bathtub and shower
surrounds; concealing pipes and columns; as
well as creating bathtub platforms, vanities,
storage shelves, countertops, and various
other bathroom structures.
The boards are simply cut to size with a utility
knife. The gridlines, which are printed on the
surface, are helpful for neat and quick cuts
and installation. KERDI-BOARD can be fully
adhered in wall areas or spot-bonded with
thin-set mortar. If necessary, the material
may be secured with additional wall anchors.
In the case of stud framing, KERDI-BOARD
is attached with screws and washers from
the matching hardware system. Tiles can be
installed directly over KERDI-BOARD using the
thin-set method.
L-shaped and U-shaped KERDI-BOARD
panels are available for creating pipe and
column coverings, and grooved panels
are available for creating curved elements.

-Systems also offers profiles and
attachment hardware for wall connections
and finishing edges, as well as matching wall
anchors and screws.
Material Properties and
Areas of Application
KERDI-BOARD is made from extruded
polystyrene foam, with a cement-free
reinforcement layer laminated to both sides
and an anchoring fleece webbing. The surface
of the board has gridlines consisting of 3/8" x
3/8" (10 x 10 mm) squares printed on one side.
KERDI-BOARD is waterproof and vapor
retardant and can withstand all chemical
stresses that typically occur in conjunction
with ceramic tile coverings. KERDI-BOARD
may be used in bonded waterproofing
assemblies where required. KERDI-BOARD
is completely flat and will not warp, even
with one-sided exposure to temperature and
moisture fluctuations. It will not rot or decay.
KERDI-BOARD can be used in a multitude of
different application areas. In special cases, the
suitability of the material must be verified based
on the anticipated chemical and mechanical
stresses. The information provided below is
intended as general guidelines.
Structures on which KERDI-BOARD is to be
installed must be stable and meet any other
project-specific requirements. Select a suitable
material thickness if using KERDI-BOARD
for the construction of freestanding partition
walls, shelving, or similar structures, and use
reinforcement profiles as necessary. Arrange
supports made of KERDI-BOARD at regular
intervals consistent with conventional building
practices. Select the material thickness and
installation method depending on the evenness
of the substrate. KERDI-BOARD can be spot-
bonded to walls to correct substrate variations
or fully embedded in thin-set mortar where
walls are sufficiently even and plumb.
Maintenance
Storage
KERDI-BOARD should be stored flat. In case
of outdoor storage, protect the material from
direct sunlight and weather exposure.
Shower Drains
Conventional two-stage drains are designed
to connect to shower pan liners below the
mortar bed and do not allow a secure,
watertight connection to bonded waterproof
membranes at the top of the drain assembly.
KERDI-DRAIN and KERDI-LINE are designed
specifically to ensure a simple and secure
connection to bonded waterproof membranes,
such as KERDI, at the top of the assembly
rather than below it, thereby reducing the risk
of leakage, efflorescence, and mold growth.
Application and Function
8.2 Schluter
®
-KERDI-DRAIN is a floor
drain specifically designed to allow connections
to KERDI or other load-bearing, bonded
waterproof membranes. The membrane is
adhered to the large integrated bonding flange
to form a waterproof connection at the top of
the drain assembly. KERDI-DRAIN consists
of a drain casing and fully adjustable grate
assembly or covering support to which tile is
applied. The grate assembly accommodates
a wide range of tile thicknesses and allows
lateral and tilt adjustment as well. The
covering support is placed flush with the
top of the bonding flange and can therefore
accommodate any thickness tile covering.
The standard KERDI-DRAIN is attached
directly to the waste line. The drain casing
is available in ABS, PVC, or stainless
steel. The plastic drain casings feature a
fleece-covered bonding flange. They are
available with standard 2" (50 mm) and 3"
(75 mm) outlets and attached to the pipe
using an appropriate solvent cement. The
stainless steel drain casings are available with
standard 2" (50 mm) or 3" (75 mm) no-hub
outlets or 2" (50 mm) threaded outlet. The
no-hub outlets are attached to the pipe using
an appropriate mechanical (e.g., flexible or
no-hub) coupling. The threaded outlets are
attached to the pipe using thread sealing
compound or tape. The simple connection to
standard drain outlets makes KERDI-DRAIN
suitable for new construction and renovation.
The KERDI-DRAIN adaptor kit is designed
to convert clamping ring drains by equipping
