Description A one part system, applied in a minimum of 2 coats at right angles. Can be used to isolate residual construction moisture where relative humidity values are up to 95%. Pigmented blue. If smoothing the subfloor before application of F78, apply either Stopgap 1200 or as a stronger alternative apply P131 overcoated with Green Bag and 114. Apply the appropriate STOPGAP smoothing underlayment directly to the F78 within 12 hours of the membrane curing to provide an absorbent surface suitable for the application of adhesive. It is not recommended to glue straight to F78. If the membrane is not covered within 12 hours of curing, a further coat must be applied and allowed to dry before proceeding with the application of the smoothing underlayment. Do not use over synthetic anhydrite or other gypsum/sulphate based subfloors. NOT suitable for use on subfloors with underfloor heating.
