What is it?
Stopgap P131 is a primer designed to promote the adhesion of Stopgap smoothing underlayments to smooth non-absorbent surfaces. It can also be used as a general purpose primer for absorbent surfaces to promote adhesion and to prevent unacceptably rapid drying of adhesives and smoothing underlayments.
Where is it used?
Stopgap P131 should be applied by roller over non-absorbent surfaces including Stopgap waterproof surface membranes, terrazzo, power floated concrete, quarry and ceramic tiles, sound asphalt, epoxy marine primers, well bonded epoxy and polyurethane coatings and minimal existing adhesive residue. It should also be used on absorbent surfaces such as concrete, sand/cement screeds, plywood, hardboard and chipboard.
Stopgap P131 is also suitable for use over normal underfloor heating installations.
What’s different about it?
Stopgap P131 is coloured green to provide the user with visual control of coverage uniformity.
