Stopgap F76

High Performance Waterproof Surface Membrane - One Coat Application System


A solvent free, two-part epoxy resin system, which chemically cures to suppress residual construction moisture in concrete and sand/cement screeds. Allowing the early instalment of moisture sensitive flooring installations in fast track building programmes or refurbishment projects.

A one-coat application system, the membrane can be used to isolate residual construction moisture where the subfloor relative humidity level is up to 92%. The system prevents moisture rising through the subfloor and causing adhesive failure and/or moisture ingression, deforming the floorcovering.

The product is pigmented blue to allow visual control of uniformity in application. To promote adhesion of the Stopgap floor smoothing underlayment, a coat of Stopgap P 131 Primer should be used.
