SHOWER SYSTEM
that retains uniform appearance during normal 
use. The surface, however, is susceptible to 
scratching and wear and may be damaged 
by grout or setting material. Cementitious 
materials, in conjunction with moisture, 
become alkaline. Since aluminum is sensitive 
to alkaline substances, exposure to the 
alkali (depending on the concentration and 
duration of exposure) may result in corrosion 
(aluminum hydroxide formation). Therefore, it 
is important to remove mortar or grout residue 
immediately from visible surfaces. In addition, 
ensure the profile is solidly embedded in the 
setting material and that all cavities are filled to 
prevent the collection of alkaline water.
The SHOWERPROFILE-WSL insert is made of 
highly flexible polyurethane. 
The SHOWERPROFILE -WSC insert is made 
of semi-rigid PVC. 
The inserts can withstand chemical stresses 
typically encountered in tiled environments.
Maintenance
SHOWERPROFILE-WS/-WSK support profiles 
require no special maintenance or care and 
are resistant to mold and fungi. In the case 
of anodized aluminum, do not use abrasive 
cleaning agents. The SHOWERPROFILE-
WSC/ -WSL inserts are specifically treated 
to resist the growth of fungi and bacteria and 
require no special maintenance or care.
Adhesive/Sealant
Any protrusions through the KERDI membrane 
can be treated with KERDI-FIX, or equivalent 
sealant, to ensure a fully waterproof assembly.
Application and Function
8.3 Schluter
®
-KERDI-FIX is a single-
component, waterproof sealing and 
bonding compound with a silane-modified 
polymer base, which can be used in various 
applications. In conjunction with KERDI, 
KERDI-FIX can be used to waterproof pipe 
and valve protrusions in the Schluter

- 
Shower System. KERDI-FIX is used to bond

the KERDI membrane to the stainless steel 
KERDI-DRAIN bonding flange. KERDI-FIX 
can also be used to bond KERDI to building 
elements such as bathtubs, window elements 
and door frames.
Material Properties and  
Areas of Application
KERDI-FIX is odorless, weather- and 
UV-resistant. The product is elastomeric, free 
of solvents, and provides a strong bond 
to most materials, including wood, stone, 
concrete, metal, glass, and many synthetic 
materials. KERDI-FIX can be painted over with 
most alkyd resins or dispersion paint types. 
The suitability of the material must be
verified based on the anticipated chemical, 
mechanical, and/or other stresses. KERDI-FIX 
is not recommended in or around swimming 
pool applications.
KERDI-FIX has been evaluated according 
to the "Standard Method for the Testing 
and Evaluation of Volatile Organic Chemical 
Emissions from Indoor Sources Using 
Environmental Chambers, Version 1.1" for 
California Specification 01350 and found to 
comply with the VOC requirements. California 
Specification 01350 is referenced by various 
green building standards and rating systems.
Maintenance
Storage
Unopened packages of KERDI-FIX can be 
stored in a cool location that is above freezing 
temperatures for up to 18 months.
Once the cartridge has been opened, the 
material has a limited shelf life.
