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:
- Prevents pinholing and rapid drying in smoothing compounds.
- Flexible dilution options (neat or diluted up to 7:1) for different substrates.
- Compatible with STOPGAP adhesives and levelling compounds.
What it solves:
- Promotes adhesion on smooth, dense subfloors.
- Reduces installation failures from poor bonding.
- Speeds up project turnaround with fast drying times.
Application Method:
- Neat on non-absorbent surfaces (coverage ~50 m²/5L)
- Diluted 4:1 for absorbent surfaces (~100 m²/5L)
- Diluted 7:1 for damp/external (~175 m²/5L)
