STOPGAP P121 is an acrylic primer designed to promote the application characteristics of STOPGAP 1100 GYPSUM, and other suitable STOPGAP smoothing underlayments, to calcium sulphate screeds e.g. anhydrite. It prevents unacceptably rapid drying of adhesives and smoothing underlayments. It is non-flammable and suitable for use over normal underfloor heating installations. STOPGAP P121 is coloured blue to provide the user with visual control of coverage uniformity.
Absorbent Concrete, sand/cement screed, plywood, hardwood and chipboard.Non-absorbent Terrazzo, steel, galvanised steel, waterproof surface membranes, epoxy, polyurethane and existing adhesive residue.Neoprene emulsion primer to promote adhesion of Stopgap smoothing underlays to both absorbent and non-absorbent surfaces. Designed to prevent rapid drying of adhesives and smoothing underlays.
Acrylic primer designed to promote adhesion of STOPGAP levelling compounds to non-absorbent subfloors. STOPGAP P141 contains recycled uPVC pulver that dries to a hard, textured surface to enhance bond performance. STOPGAP P141 is recommended when applying STOPGAP 600 over non-absorbent surfaces at thicknesses over 20mm. It is suitable for use over normal underfloor heating and is pigmented yellow for visual control of coverage uniformity.
