Schluter KERDI-BOARD TearPad

Lightweight, waterproof tile backer for
showers and bathtub surrounds.
Schluter®-KERDI-BOARD
Tiled showers and bathtub surrounds require
proper moisture management to ensure successful
long-term performance. KERDI-BOARD is lightweight, easy to cut, inherently waterproof and
vapor-retardant, thus greatly reducing the prep work
required to create an ideal substrate for the application
of tiles in wet areas.
Multifunctional tile substrate
- Waterproof and vapor-retardant
- Thermally insulating, reduces heat loss
- Dimensionally stable
Simplifies tile installation
- Lightweight, easy-to-handle and transport
- Easy-to-cut and dust-free
- Printed gridlines for precise cutting
- Quick and easy to install

Material properties:
Requirements:
KERDI-BOARD consists of an extruded polystyrene foam panel, with
a special reinforcement facer on both sides and fleece webbing for
effective anchoring in thin-set mortar.
Structures on which KERDI-BOARD is to be installed must be
stable and meet local building code and any other project-specific
requirements.
Application:
IMPORTANT: The maximum allowable stud spacing for the
application of KERDI-BOARD is 16" (40 cm). Stud spacing
exceeding 16" will require the placement of additional studs to
meet this requirement.
The 1/2" thick (12.5 mm) KERDI-BOARD can be applied over existing
gypsum or masonry walls, wood stud framing, and other finished wall
surfaces for bathtub and shower surrounds.
