-KERDI-BOARD

Application and Function

12.1 Schluter

-KERDI-BOARD is a

multifunctional tile substrate and building panel,

which can also be used for creating bonded

waterproofing assemblies with tile coverings.

It consists of an extruded polystyrene foam

panel, with a special reinforcement material

on both sides and fleece webbing for effective

anchoring in thin-set mortar.

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 or spot-

bonded in existing or masonry wall areas 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. Schluter-Systems

also offers profiles and attachment hardware

for wall connections and finishing edges, as

well as matching wall anchors and screws.

12.1 Schluter

-KERDI-BOARD-SB/-SC are

prefabricated substrates, made of Schluter

KERDI-BOARD, which integrate with the

-Shower System. The substrates are

waterproof and ready for tile, leaving only

sealing of joints and corners to complete

waterproofing. The KERDI-BOARD-SB shower

bench is available in triangular and rectangular

configurations in the followings sizes (width x

depth x height). The triangular benches are 16"

x 16" x 20"

(41 x 41 x 51 cm) and 24" x 24" x 20"

(61 x 61 x 51 cm). Rectangular benches

are 38" x 16" x 20" (97 x 41 x 51 cm)

and 48" x 11-1/2" x 20" (122 x 29 x 51

cm). The KERDI-BOARD-SC shower curb

can be used in conjunction with any shower

base. Curb dimensions are 38" x 6" x 4-1/2"

(97 x 15 x 11.5 cm) and 48" x 6" x 4-1/2" (122

x 15 x 11.5 cm).

The tiles can be installed immediately using Schluter SET™, Schluter ALL-SET™, Schluter FAST-SET™ or unmodified thinset mortar. 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.

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 KERDIBOARD-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.
