COVERAGE will be approximately 3kg/m2 dependent upon depth and porosity of the screed. Weaker, more porous screeds may require up to 5kg/m2. STOPGAP SRS is a solvent free low viscosity two component renovation material designed to quickly stabilise and reinforce screeds comprising of cement and calcium sulphate, including those containing hot water heating pipes. The product readily fills voids and cracks resulting from poor placement and curing techniques of screeds. The product may also be used over certain cement based screeds containing high levels of construction moisture or where no effective damp proof membrane is present, prior to the application of STOPGAP F77 Waterproof Surface Membrane (Protocols for the use of STOPGAP F77 must be observed). This product will not be as effective on saturated screeds. An assessment should be made of the screed in question to determine the likelihood of success.
