5. The tiles can be installed using
unmodified thin-set mortar once the
bonding materials used to construct the
element have cured sufficiently to
stabilize the assembly. Choose a
notched trowel to match the tile format,
and back-butter the tiles, if necessary,
to attain full coverage
Note: See section “Waterproofing” on
the use of KERDI-BOARD in bonded
waterproofing assemblies.
Waterproofing with KERDI-BOARD
Where waterproofing is desired, the joints
and corners of Schluter
®
-KERDI-BOARD in
the area must be sealed with Schluter
®
-
KERDI-BAND using unmodified thin-set
mortar. The KERDI-BAND must overlap
panel joints by at least 2" (50 mm).
KERDI-BAND is also suitable for sealing
connections to fixed building elements such
as door and window frames. Where these
surfaces will not accept a bond to
unmodified thin-set mortar, use Schluter
®
-
KERDI-FIX to bond KERDI-BAND.
Separate KERDI-BOARD above the existing
movement joints and structural joints and
cover the joints with Schluter
®
-KERDI-FLEX
using unmodified thin-set mortar, ensuring a
minimum 2" (50 mm) overlap.
Fastener penetrations may be sealed with
KERDI-BAND using unmodified thin-set
mortar.
Please refer to the Schluter
®
-Shower
System Installation Handbook for guidelines
on waterproofing showers, steam showers,
and tub surrounds.
Note: Certain glass tiles may not be
compatible with bonded waterproofing
applications and/or may require special
setting materials. Consult glass tile
manufacturer and Schluter
®
-Systems for
more information.
Certain moisture-sensitive stones, e.g.,
green marble, or resin-backed tiles may not
be appropriate for use in wet areas or may
require special setting materials. Consult
stone supplier and Schluter
®
-Systems for
more information.
If installing bathroom fixtures such as grab
bars in showers, wall-mounted toilets, or
other heavy objects, the fixtures must be
anchored in the structure or solid blocking
behind KERDI-BOARD.
Note: Reinforcement may be required
behind the entire footprint of the object.
For example, place solid blocking behind
the base of a wall-mounted toilet installed
over KERDI-BOARD on stud framing.
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: As an alternative, you can also
cut a single U-shaped panel into two L-
shaped panels with shorter legs.
Note: See section “Waterproofing” on
the use of KERDI-BOARD in bonded
waterproofing assemblies.
Curved wall areas made of KERDI-
BOARD
1. The Schluter
®
-KERDI-BOARD-V panels
feature grooves to allow for quick and
easy creation of curved elements.
2. First, cut the panels to the required size.
If a larger expanse of panels is required,
several panels can be connected along
the edges with thin-set mortar,
Schluter
®
-KERDI-FIX adhesive, or the
Schluter
®
-KERDI-BOARD-ZDK double-
sided adhesive tape.
3. If the grooved surface points toward the
inside, it is recommended that the
grooves be filled with thin-set mortar
prior to panel installation.
4. Outward-facing grooves should be filled
with thin-set mortar prior to or during
the tile installation.
