wedi® Subliner Dry Waterproofing Membrane is a sheet waterproofing membrane designed for sealing interior wall and floor assemblies beneath tile installations. It installs over approved substrates, including drywall and standard underlayments, and is intended for use under ceramic tile, slabs, and natural stone.
As a high-performance shower waterproofing membrane, Subliner Dry provides reliable moisture and vapor control for wet areas, including steam showers and steam rooms. The tile waterproofing membrane has a vapor resistance rating of 0.09 WVTR/Perms when tested in accordance with ASTM E96, Method E.
Key Features
- Waterproofing Membrane: Designed to create a continuous waterproof barrier beneath tile installations in wet areas.
- 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.
