Sopraseal VP Primer is a solvent-based liquid primer formulated specifically to enhance the adhesion of Sopraseal Stick VP self-adhesive vapour-permeable air barrier membranes on challenging or porous substrates where jobsite conditions may otherwise compromise membrane performance.
Ideal For: Surface preparation prior to Sopraseal Stick VP installation on exterior gypsum boards, wood, OSB, concrete, and concrete block walls — particularly in cold-weather conditions, highly porous substrates, or other jobsite situations where direct membrane adhesion may be insufficient without pre-treatment.
