wedi® Subliner Dry is a waterproofing membrane designed for sealing interior wall and floor assemblies over existing substrates, including drywall and standard underlayments. It is intended for use beneath ceramic tile, slabs, and natural stone in indoor applications.
The membrane provides reliable waterproofing and vapor resistance for wet areas, including steam showers and steam rooms. Subliner Dry has a vapor resistance rating of 0.09 WVTR/Perms when tested in accordance with ASTM E96, Method E.
Key Features
- Waterproof and Vapor-Resistant Membrane: Designed for wet areas requiring both moisture and vapor control.
- Steam Shower Rated: Suitable for steam shower and steam room installations.
- Pliable Sheet Construction: Strong yet flexible material supports easier handling during installation.
- Printed Installation Guides: Measuring references and cutting lines are printed directly on the membrane surface.
- System-Based Installation: Designed to be used with wedi® system components and accessories.
Installation Notes
- Seams are sealed using wedi® Sealant 620 to create waterproof and vaporproof connections.
- Sealant-applied seams form a continuous barrier that does not allow water or vapor transmission.
- The sealing method differs from taped and mortared seams, which may allow moisture absorption.
