A two part, one coat system for use up to 98% RH or for use with underfloor heating to a maximum of 90% RH. Pigmented black. If the subfloor is smooth and flat, F77 can be applied and B95 can then be applied directly to F77. STOPGAP 1200 can be applied directly to the membrane within 24 hours of curing. If smoothing the subfloor before application of F77, apply either Stopgap 1200 or as a stronger alternative apply P131 overcoated with Green Bag and 114. Do not use over synthetic anhydrite or other gypsum/sulphate based subfloors. Suitable for use on subfloors with underfloor heating. Coverage: ≤ 98% RH: 1.8sqm/kg underfloor heating ≤ 90% RH: 1.8sqm/kg ≤ 85% RH: 2.5sqm/kg Working time: 30 minutes (20°C) Full Cure: 3hrs (20°C)
