KERDI-SEAL-PS/-MV 8 Use KERDI-KERECK-F pre-formed inside and outside corners to seal the shower curb to the wall and mortar base. The curb/base junction is sealed using KERDI-BAND. Cover the curb with KERDI. 9 Protect walls and ceiling* from moisture and vapor penetration using KERDI. Seams are constructed by overlapping the edges of KERDI by 2" (50 mm) minimum or by butting adjacent sheets of KERDI and installing KERDI-BAND, centered over the joint. *Applies when installing KERDI on the ceiling.

BARRIER-FREE SHOWERS Accessibility and style As our population ages, there is increasing demand for accessible living spaces. Tiled showers typically feature curbs to retain water in the stall, which can make entry difficult for those with limited mobility, including individuals who need the assistance of wheelchairs. Barrier-free tiled showers eliminate the use of a curb and rely on the slope of the floor to keep water inside the stall, thus improving accessibility.
The WATERPROOF Bathroom Security and utility Bathrooms are a primary focus of today’s building and remodeling projects and are becoming more and more luxurious, complete with steam showers, oversized bathtubs, and the latest in fixtures and lighting. As such, tiled showers, bathtub surrounds, floors, walls, and vanities are in high demand. Tile and stone are beautiful, durable, and available in a wide range of formats, colors, and textures, allowing limitless design options.
Floors can be made fully waterproof with Schluter®-DITRA. Since the membrane is made of waterproof polyethylene, the only extra step necessary is to seal the seams and floor/wall connections with KERDI-BAND. The same practice is used to integrate the DITRA with the Schluter®KERDI used to waterproof the shower or tub surround. The result is a comprehensive waterproofing system that protects against moisture penetration.
PROFILES Unleash your creativity Finishing and edge protection Ceramic and stone tiles are durable, easy to maintain, and hygienic, representing the ideal surface coverings for showers and bathtub surrounds. Exposed tile edges, however, are unsightly and prone to cracking and chipping.
Maintenance-free inside corners Ceramic cove base represents a neat, hygienic method for treating transitions at inside corners by providing a curved surface that prevents the collection of dirt and is easy to clean. However, the limited availability of ceramic trim pieces has resulted in the use of sealant and caulk to treat such transitions. These joints must be continually maintained throughout the life of the installation.
THIN-SET FACTS Discussion on thin-set mortars and Schluter®-KERDI installations QUESTION: Should a latex-modified thin-set mortar or an unmodified thin-set mortar be used to install Schluter®-KERDI? ANSWER: The type of bonding mortar used to apply Schluter®-KERDI must be suitable for the substrate and mechanically anchor the fleece on the KERDI. For all the substrates listed in this Handbook (e.g., gypsum board, cement backerboard, etc.), an unmodified thinset mortar is recommended.
TESTING, LISTINGS, & APPROVALS Products and system evaluation Schluter®-Systems is committed to providing reliable installation systems for tile and stone. As part of this commitment, we have invested considerable resources in testing our products and obtaining listings and approvals through various certification organizations to provide our customers and local code officials with relevant data that supports the efficacy of our system.
MOLD The importance of mold control The term “mold” is used to describe visible fungal growth. Mildew is another common term which refers to the type of fungi found growing on window sills and in bathrooms. Fungi are everywhere in our environment and are found both indoors and outdoors. However, the type and amount found in the home can be an important health issue. Understanding how to effectively control mold growth is very important. What is Mold? Fungi are different from plants and animals.
VAPOR The importance of water vapor management Why is water vapor management important? It is important to consider that water exists as both liquid and vapor in showers, and must be managed in both forms. The prime example of this is the steam shower. Steam showers that are not designed to manage water vapor have caused mold growth in wall cavities, rot in wood framing, and damage to moisture-sensitive wall coverings on the opposite side of the stud cavities.

3 Schluter®-KERDI Schluter®-KERDI is a pliable sheet-applied polyethylene waterproofing membrane and vapor retarder that guarantees uniform thickness. It is covered on both sides with a fleece webbing to anchor the membrane in thin-set mortar. Schluter®-KERDI is ideal for waterproofing floors and walls, including steam showers.
Schluter ®-KERDI-SHOWER-KIT Schluter®-KERDI-SHOWER-KIT is an all-inclusive package containing each of the integrated family of components required to create a watertight shower assembly without a mortar bed. This includes a prefabricated tray, which is available in different sizes, curb, KERDI membrane, KERDI-BAND, KERDI-KERECK-F pre-formed corners, and the KERDI-DRAIN.
Schluter ®-KERDI-FIX Schluter®-KERDI-FIX is a sealing and bonding compound with a silane-modified polymer base which is used to seal penetrations through the Schluter-KERDI waterproofing membrane. It is also used to bond the KERDI membrane to the stainless steel version of the KERDI-DRAIN. KERDI-FIX is odor-neutral, UV- and weather-resistant, and contains no solvents. It is elastomeric and bonds well to most materials, such as wood, stone, concrete, metal, glass, and many plastics.
