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.

Preformed, seamless corners include the

following. KERDI-KERECK-F are used to

seal 90° inside and outside corners. KERDI-

KERS-B are used to seal 135° corners at

triangular shower benches and neo-angle

shower curbs. KERDI-KERS are used to

seal 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 modified polyethylene

(PEVA) core with non-woven polyproplyene

on both sides. KERDI-DS features a high-

density polyethylene (HPDE) core with non-

woven polyproplyene on 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
