Product Description
MVP4® Moisture Vapor Protection is a one-part, trowel applied, moisture cure urethane membrane designed to be used beneath glue-down installations of engineered, solid and bamboo hardwood flooring. MVP4 is exceptionally easy to trowel and is designed to minimize moisture vapor transmission from the subfloor, create a noise reduction barrier over the substrate, and establish an anti-fracture membrane that can bridge cracks that can occur in the substrate prior to or after installation (up to 1/8″). MVP4 may be applied prior to any Bostik hardwood adhesive to achieve a warranty for unlimited moisture vapor protection.
Features of MVP4® Moisture Vapor Protection
- Unlimited moisture vapor protection
- Noise reduction typical of 1/4″ cork*
- Allows visual inspection of membrane prior to flooring installation
Applications of MVP4® Moisture Vapor Protection
MVP4® Moisture Vapor Protection can be used for:
- Engineered flooring
- Solid flooring
- Bamboo hardwood flooring
