STOPGAP P131 – General Purpose Primer (5 Litre)
STOPGAP P131 is a versatile general-purpose primer designed to promote adhesion of STOPGAP smoothing compounds to both absorbent and non-absorbent subfloors. Its formulation prevents the rapid drying of adhesives and levelling compounds, ensuring a stronger, longer-lasting bond.
Who it’s for:
Flooring contractors and installers preparing subfloors for gym flooring, resilient coverings, and commercial fit-outs.
✅ Multi-Purpose Use
Effective on concrete, sand/cement screeds, plywood, chipboard, asphalt, ceramic tiles, epoxy membranes, and more.
🎯 Coverage Control
Green pigment ensures visible application, reducing the risk of missed spots.
⚡ Fast Drying
Dries within 20–30 minutes on absorbent surfaces, ~60 minutes on non-absorbent.
🌱 Safe & Reliable
Water-based, non-toxic, and suitable for underfloor heating and marine applications.
Why it’s superior:
