ProVap S.A. VCL Spray Primer is a rapid-drying, non-flammable primer formulated with SBS resins to promote strong, long-lasting adhesion between ProVap VCL membranes and a wide range of porous substrates. The convenient spray application allows for fast, even coverage — ideal for large-scale or detailed flat roofing projects.
The ProVap S.A. VCL Spray Primer is a high-performance primer specifically designed for use with ProVap vapour control layers and modified bitumen roofing systems. Its SBS resin formulation delivers excellent adhesion while maintaining flexibility and durability under thermal movement.
Supplied in 750ml aerosol cans for small areas or detail work, and 22L canisters for large-scale application, this spray primer provides a fast, uniform finish with minimal overspray or waste. Its non-flammable solvent base ensures safer use on-site while maintaining compatibility with concrete, OSB, plywood, and other porous roofing substrates.
Ideal for use in both new build and refurbishment projects, ProVap Spray Primer performs exceptionally well in cooler conditions, ensuring consistent membrane bonding at temperatures as low as +5 °C.
