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.

Pre-formed sections of KERDI are

available for inside and outside corners,

pipe protrusions and mixing valve openings.

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.

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.

KERDI is waterproof and resistant to most

chemicals commonly encountered in tiled

environments. It is resistant to aging and

will not rot. KERDI is highly resistant to

saline solutions, acid and alkaline solutions,

many organic solvents, alcohols, and oils.

Information regarding its resistance to specific

substances can be provided if concentration,

temperature, and duration of exposure are

known. For acid-resistant coverings, use an

epoxy adhesive to set and grout the tile.

KERDI is suitable for wall and floor surfaces

where protection against the penetration

of moisture or other harmful substances is

necessary. Applications include showers,

intermittent use steam showers, tub

surrounds, and areas surrounding swimming
