Stopgap F77
High performance accelerated waterproof surface membrane one-coat application system.
A solvent free two part epoxy resin system which cures to provide a waterproof surface membrane.
Not suitable for use over synthetic anhydrite subfloors.
It impedes the passage of residual construction moisture and rising damp from affecting subsequent floorcovering installations, therefore allowing early installation of floorcoverings 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 %.
Rough, uneven or damaged concrete or sand/ cement screeds must be smoothed/ repaired with Stopgap 1200 Pro, Stopgap Green Bag/ 114 liquid or Stopgap 460 Exterior Repair.
Prime the surface with neat Stopgap P131 primer.
Features:
- Impedes the passage of construction moisture and rising damp up to 98% relative humidity with a single coat application.
- Colour pigmented to aid coverage uniformity.
- Can be applied direct over underfloor heating screeds using a coverage of 1.8 m²/kg where readings are up to 90 % relative humidity.
