STOPGAP FILL AND PRIME is a two-component, fast drying flexible cement based primer suitable for use over raised access panels and substrates with well- bonded, waterproof residues of adhesives prior to the direct application of STOPGAP 1200 PRO.

STOPGAP FILL AND PRIME has been designed to have a thixotropic consistency which enables joints up to 4mm wide to be filled in raised access panels. Applied up to a thickness of 1mm, STOPGAP FILL AND PRIME sets rapidly and is ready to receive foot traffic in as little as 60 minutes. Once cured, the flexible nature of the product will accommodate movement within the substrate.

STOPGAP FILL AND PRIME can be applied to flooring grade wooden substrates such as plywood, orientated strand board (OSB 3), particle board (chipboard) conforming to BSEN 312 Annex A P4-P7 and medium density fibreboard, prior to the application of STOPGAP 700 SUPERFLEX. STOPGAP FILL AND PRIME may also be used to smooth out uneven tongue and groove floorboards prior to over boarding with plywood.

STOPGAP FILL AND PRIME offers exceptional adhesion to a wide range of other subfloor types including STOPGAP waterproof surface membranes, sand/cement screed, concrete, sound asphalt, granolithic, terrazzo, epoxy and polyurethane resins, ceramic and quarry tiles.


A 4kg bag of STOPGAP FILL AND PRIME Powder mixed with 2.5 litres of STOPGAP FILL AND PRIME Liquid will cover approximately 8.5m2 at a thickness of 0.5mm.
