INNOVATIVE SOLUTIONS FOR CERAMIC AND STONE TILE

BONDED WATERPROOF MEMBRANES AND VAPOR RETARDERS

Ceramic and stone tiles are durable, easy

to maintain, and hygienic, representing

ideal surface coverings in wet areas.

However, since tiles and grout are not

inherently waterproof, it is essential to

protect the substrate from moisture

penetration.

Application and Function

8.1 Schluter

-KERDI is a pliable, sheet-

applied, bonded waterproof membrane and

vapor retarder 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.

KERDI was developed as a

waterproofing membrane to be used in

conjunction with ceramic and stone tile

coverings. Tiles can be installed directly

on KERDI using the thin-bed method. Other

trowel-applied covering materials, such as

plaster, can also be used.

Schluter

-KERDI-DS is a bonded

waterproofing membrane and vapor

retarder with very low water vapor

permeance for use in continuous use

steam rooms and similar applications.

Various KERDI waterproofing accessories

are available. Use 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.

KERDI-FLEX, in 5" (12.5 cm) or 10" (25 cm)

widths, is used to seal expansion joints or

flexible edge joints.

KERDI-KERS-B are preformed, seamless

corners for waterproofing 135° angles

between triangular shower benches

and walls or tops of curbs in neo-angle

shower applications. KERDI-KERS are

preformed, seamless corners made of

KERDI for waterproofing floor/wall/shower

base connections in curbless shower

applications where the KERDI-LINE linear

drain is installed adjacent to the wall.

KERDI-SEAL-PS/-MV are prefabricated

sections of KERDI with overmolded rubber

gaskets that are used to seal pipe protrusions

through the KERDI waterproofing membrane

(e.g., at showerheads and tub spouts) and

protect moisture-sensitive backing panels

at the mixing valve.

Material Properties and

Areas of Application

KERDI features a polyethylene core with

a polypropylene fleece laminated to both

sides. The material is physiologically safe

and does not require special disposal.

KERDI is 8-mil thick and has a water vapor

permeance of 0.90 perms, when tested

according to ASTM E96, using Procedure

E at 90% relative humidity. KERDI-DS

is 20-mil thick and features additives to

produce a water vapor permeance of 0.18

perms.
