Schluter-KERDI is a bonded waterproof membrane with limited crack-bridging capabilities. It is made of soft polyethylene, which is covered on both sides with a special fleece webbing to anchor the membrane in the thin-set mortar.

Schluter-KERDI was developed as a waterproofing membrane to be used in conjunction with ceramic and stone tile coverings. Tiles can be installed directly on Schluter-KERDI using the thin-bed method. Other trowel-applied covering materials, such as plaster, can also be used.

Pre-cut sections of Schluter-KERDI are available for inside and outside corners, as well as for pipe collars. Use Schluter-KERDI-BAND, in widths of 5" (12.5 cm), 7-1/4" (18.5 cm), or 10" (25 cm) to seal butt joints or corner joints. Schluter-KERDI-FLEX, in 5" (12.5 cm) or 10" (25 cm) widths, is used to seal expansion joints or flexible edge joints.





The Schluter-KERDI-SHOWER-KIT is an all inclusive package containing each of the components required to create a maintenance-free, watertight shower assembly without a mortar bed.

Schluter-KERDI-SHOWER-ST/-SC are prefabricated substrates, made of expanded polystyrene foam, for tiled shower bases in conjunction with Schluter-KERDI waterproofing membrane and Schluter-KERDI-DRAIN. Schluter-KERDI-SHOWER-ST is a prefabricated, sloped shower tray that is specifically designed to accept the Schluter-KERDI-DRAIN and Schluter-KERDI waterproofing membrane. The tray is available in 48" x 48" (122 cm x 122 cm), 32" x 60" (81 cm x 152 cm), and 72" x 72" (183 cm x 183 cm) sizes. Schluter-KERDI-SHOWER-SC is a prefabricated curb that can be used with Schluter-KERDI-SHOWER-ST. Curb dimensions are 48" x 6" x 4-1/2" (122 cm x 15 cm x 11.5 cm).

The integrated Schluter-Shower System eliminates the potential for leakage, efflorescence, and mold growth in the system, is maintenance-free, and dramatically reduces total installation time to ensure success and make shower installation easier than ever. Schluter prefabricated shower substrates provide an alternative to shower bases constructed of mortar. The shower tray and curb are especially useful in large-scale, repetitive jobs, such as hotels, apartments, and condominiums for the significant time savings that can be realized.




Ceramic and stone tiles are durable, easy to maintain, and hygienic, representing the ideal surface coverings. However, today's lightweight construction methods can make the installation of hard surface coverings particularly challenging. In order to protect the integrity of the tile assembly, an underlayment that performs multiple functions is required.

Schluter-DITRA is a polyethylene membrane with a grid structure of square cavities, each cut back in a dovetail configuration, and an anchoring fleece laminated to its underside. Schluter-DITRA is bonded to the substrate using thin-set mortar. The anchoring fleece on the underside of Schluter-DITRA is fully engaged in the mortar to provide a mechanical bond to the substrate. Tile is installed over Schluter-DITRA using the thin-bed method in such a way that the mortar becomes mechanically anchored in the square, cutback cavities of the Schluter-DITRA matting.

Designed specifically for ceramic tile and dimension stone installations, Schluter-DITRA serves as an uncoupling layer, waterproofing membrane, and vapor management layer that accommodates moisture from beneath the tile covering. Further, DITRA performs all these functions while still providing adequate support/load distribution for the tile covering.

Edge Protection & Transition Profiles for Floors


Schluter-SCHIENE finishes and protects the edges of tiled surfaces at transitions to other surface coverings of the same height, such as tile bordered by carpet.


Schluter-DECO finishes and protects the edges of tiled surfaces at transitions to other surface coverings of the same height, such as wood or carpet. The exposed surface of the Schluter-DECO is wider than the Schluter-SCHIENE and can also be used to create decorative lines within tile fields.


Schluter-RENO-T overlaps the edges of adjoining floor covering surfaces of the same height (e.g., ceramic tile or natural stone, parquet flooring, concrete pavers, laminate, etc.). Schluter-RENO-T can be installed during the tile installation or retrofit an existing installation.


Schluter-RENO-TK provides a sloped transition between tiled surfaces and lower adjoining floor coverings, typically carpet. The sloped flange of the profile hides and protects the cut edge of the lower adjoining surface covering.


Schluter-RENO-U is designed to provide a smooth transition from tile to lower floor coverings with a 4 mm edge that abuts the lower surface covering.


Schluter-RENO-RAMP provides a gradual transition between tiled surfaces and lower adjoining floor coverings. Ideal for commercial applications where wheel carts are used (e.g., bakeries, hospitals, etc.).


Schluter-RENO-V is an adjustable transition profile designed to provide a sloped transition between tiled and lower adjoining floor coverings. The movable transition arm allows the profile to adjust to the height of the lower adjacent floor covering.
