NEOPRENE PRIMER 940 is a spray grade contact cement/rust inhibiting primer with a flammable solvent vehicle designed as a tie coat for dusty or porous surfaces to improve adhesion to a variety of substrates. NEOPRENE PRIMER 940 penetrates into the surface to lock itself into place to provide excellent anchorage for topcoats and sprayed-in-place polyurethane insulation.
RECOMMENDED USES:
NEOPRENE PRIMER 940 may be used as a primer coat over a wide range of substrates which include, but are not limited to, BUR, asphalt, wood, metal, concrete, masonry, various single ply membranes, polyurethane foam and most conventional roof coatings. It is pigmented black to speed the curing process and increase roof surface temperature before application of sprayed-in-place polyurethane foam or roof coatings. NEOPRENE PRIMER 940 may also be used as a temporary protective coat over polyurethane foam when weather conditions prevent application of acrylic coatings.
APPLICATION INSTRUCTIONS:
NEOPRENE PRIMER 940 may be applied by medium nap rollers or conventional airless spray equipment. Apply NEOPRENE PRIMER 940 only to clean, dry, sound surfaces free of loose particles or other foreign matter. Apply NEOPRENE PRIMER 940 at the rate of 3/4 to 1 gallon per 100 sq. ft., according to substrate and condition. Normal drying time is 1-2 hours.
