Advanced Sheet-Applied Waterproofing for Tiled Surfaces
Schluter KERDI Waterproofing Membrane is a high-performance sheet membrane designed to create a reliable waterproof barrier beneath ceramic and stone tile installations. Engineered with a modified polyethylene (PEVA) core and non-woven polypropylene fleece on both sides, the membrane bonds securely with thin-set mortar to form a durable, tile-ready surface.
This system allows tiles to be installed directly over the membrane using the thin-bed method, simplifying installation while ensuring long-term moisture protection in showers, bathrooms, and other wet areas.
Engineered Membrane Construction for Secure Mortar Bonding
The unique layered structure of Schluter KERDI ensures excellent adhesion and consistent performance across a wide range of tile installations. The fleece layers on both sides of the membrane allow the thin-set mortar to mechanically anchor into the material, forming a strong bond with the substrate and tile covering.
Key structural features include:
-
Modified polyethylene (PEVA) waterproof core
-
Non-woven polypropylene fleece on both sides
-
Anchoring surface designed for thin-set mortar bonding
-
Consistent 8-mil membrane thickness for uniform protection
This engineered design helps maintain system integrity while simplifying installation for professionals and experienced DIY installers.
Effective Moisture and Vapor Protection for Wet Areas
Water intrusion behind tiled surfaces can lead to structural damage, mold growth, and costly repairs. Schluter KERDI acts as both a waterproofing membrane and a vapor retarder, helping to protect building materials from moisture penetration.
By installing the membrane directly beneath tile coverings, the system prevents water from reaching underlying substrates while maintaining a controlled vapor barrier. This makes it particularly suitable for environments exposed to frequent moisture.
Designed for Tile Installations on Walls and Floors
Schluter KERDI was specifically developed for use with ceramic and stone tile assemblies. Once installed, tiles can be applied directly onto the membrane using appropriate thin-set mortar, creating a secure and waterproof tile system.
Typical applications include:
-
Shower walls and floors
-
Bathtub surrounds
-
Bathroom walls and wet areas
-
Residential and commercial tiled floors
-
Moisture-prone interior spaces
The wide roll format also reduces the number of seams required, helping improve installation efficiency.
Large Roll Coverage for Faster Installation
The membrane is supplied in a wide roll designed to cover large wall sections in a single application. With a width of approximately 6 ft 7 in (2 meters), the material can often extend from the shower floor to standard showerhead height, minimizing seams and simplifying installation.
Fewer seams mean:
-
Reduced installation time
-
Improved waterproof continuity
-
Simplified layout and cutting
This makes Schluter KERDI an efficient solution for professional tile installers and renovation projects.
Low-Emission Material Suitable for Modern Building Standards
Schluter KERDI has been evaluated for indoor air quality performance and meets the VOC emission requirements outlined in California Specification 01350. This standard is referenced by several green building programs and environmental rating systems.
The membrane’s compliance supports its use in projects that prioritize healthier indoor environments while maintaining high waterproofing performance.
