Stopgap P131

Neoprene emulsion primer designed to promote adhesion of smoothing underlayments to smooth, non-absorbent surfaces, such as steel, epoxy and polyester floors. Can be used as general purpose primer for absorbent surfaces to promote adhesion, and prevent unacceptably rapid drying of adhesives and underlayments. It is:

  • Non-flammable.
  • Suitable for use over normal underfloor heating installations.
  • Coloured green, offering visual control of coverage uniformity.

For use on absorbent surfaces, such as concrete, sand/cement screeds, plywood, hardboard and particleboard, and non-absorbent surfaces of terrazzo, power float concrete, quarry and ceramic tiles, asphalt, steel, galvanised steel, Stopgap F75 and Stopgap F76 waterproof surface membranes, and residues of epoxy, polyester, and existing adhesive.

General information
