F Ball & Co F77 Damp Proof Membrane (7kg Kit)

STOPGAP F77 DPM is a solvent free two part epoxy resin system which cures to provide a waterproof surface membrane. STOPGAP F77 impedes the passage of residual construction moisture and rising damp from affecting subsequent floorcovering installations, allowing early installation of floorcoverings in fast track building programmes. STOPGAP F77 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%. 

"This solvent-free, two-part epoxy resin system offers unrivalled protection and performance for installations where a waterproof surface membrane is required, and creates an impenetrable barrier against moisture in a one-coat application".
