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.

-KERDI-BOARD-SB/-

SC are prefabricated substrates, made of

Schluter

-KERDI-BOARD, which integrate

with the Schluter

-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).

Schluter

-KERDI-BOARD-SN is a

prefabricated shower niche made of

KERDI-BOARD that can be installed in both

Schluter

-KERDI and KERDI-BOARD wall

assemblies. The shower niche features a

1/2" (12.5 mm) -thick by 2" (50 mm) -wide

integrated bonding flange and is available

in 12" x 6" (30 cm x 15 cm), 12" x 12"

(30 cm x 30 cm), 12" x 20" (30 cm x 51 cm),

and 12" x 28" (30 cm or 71 cm) sizes.

S c h lut e r ® -K ER DI- B OAR D 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 mm x 10 mm) squares printed on one side. KERDI-BOARD is waterproof and vaporretardant and can withstand all chemical stresses that typically occur in conjunction with ceramic tile coverings.

Use of KERDI-BOARD in non-bearing partition wall systems Minimum board thickness = 2" (50 mm) 1. Schluter®-KERDI-BOARD is adhered to the permanent wall in such a way as to provide lateral stability. This can be achieved by sandwiching the panel between adjacent KERDIBOARD panels, fixed building elements, etc.

S c h lut e r ® -K ER DI- B OAR D 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 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.
