    STOPGAP F77 is a solvent free two part epoxy resin system which cures to provide a waterproof surface membrane.

    F77 impedes the passage of residual construction moisture and rising damp from affecting subsequent floor covering installations, allowing early installation of floor coverings in fast track building programmes. It is pigmented black to allow the user to visually control coverage uniformity.

    It can be used to isolate residual construction moisture where relative humidity values are up to 98% and applied directly over underfloor heating screed with RH readings up to 90%. When the membrane has fully cured apply a coat of Stopgap P131 Primer.

    FEATURES

    • Impedes the passage of construction moisture and rising damp up to 98% RH with a single coat application

    • Colour pigmented to aid coverage uniformity

    • Can be applied direct over underfloor heating screeds using a coverage of 1.8m²/kg where readings are up to 90% RH

    • Approximate cure time of 3 hours at an ambient temperature of 20°C

    • 7kg kit = 12.5m² coverage, 14kg kit = 25m² coverage (approx.)
