align them appropriately.
5. The tiles can be installed immediately
using unmodified thin-set mortar.
Choose a notched trowel to match the
tile format, and back-butter the tiles, if
necessary, to attain full coverage.
Note: If the bond between the thin-set
mortar and substrate is questionable,
additional mechanical attachment with

is required. Fasteners are installed after
the thin-set mortar has hardened.
Note: See section “Waterproofing” on
the use of KERDI-BOARD in bonded
waterproofing assemblies.
Spot-bonded KERDI-BOARD
Minimum board thickness = 3/8" (9 mm)
1. Remove all surface contaminants from
the substrate that may weaken the
bond.
2. Place spots of thin-set mortar on the
Schluter

-KERDI-BOARD panel or
substrate in intervals of approx. 12" (30
cm). The mortar must bond to the
substrate and mechanically anchor the
fleece on the KERDI-BOARD surface.
3. Apply the panels to the wall, firmly press
them in place, and align them with a
straight-edge or level.
4. The tiles can be installed immediately

ZT washers and corresponding screws
is required. Fastener locations must
coincide with mortar spots. This may
be ensured by making holes in the
KERDI-BOARD at the desired fastener
locations prior to applying mortar spots.
Fasteners are installed after the thin-set
mortar has hardened.
Note: See section “Waterproofing” on
the use of KERDI-BOARD in bonded
waterproofing assemblies.
Use of KERDI-BOARD on wood or
metal framing
Minimum board thickness = 1/2" (12.5 mm)
for studs spaced at 16" (40.6 cm) o.c.; 3/4"
(19 mm) for studs spaced at 24" (61.0 cm)
o.c.
1. Schluter
®
-KERDI-BOARD can be
mounted vertically or horizontally on
wood or metal framing with screws and
corresponding Schluter
®
-KERDI-
BOARD-ZT washers. Abut the
individual panels over the center of the
studs or other solid backing.
2. The selected screws must be of
sufficient length to reach a depth of at
least 3/4" (20 mm) in wood studs and
at least 3/8" (10 mm) in metal studs.
The maximum allowable on-center
fastener spacing is 12" (30 c m).
Screws may be placed between
adjacent panels such that the washers
fasten both panel edges.
3. The tiles can be installed immediately
using unmodified thin-set mortar.
Choose a notched trowel to match the
tile format, and back-butter the tiles, if
necessary, to attain full coverage.

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

Any board thickness suitable
1. Remove all surface contaminants from
the substrate that may weaken the
bond.
2. Apply thin-set mortar to the substrate
and/or onto KERDI-BOARD with a
notched trowel. The mortar must bond
to the substrate and mechanically
anchor the fleece on the KERDI-
BOARD surface.
3. Apply the panels to the wall and firmly
press them in place to ensure full
