PrimeLock Acrylic Primer


PrimeLock Acrylic Primer is an excellent adhesion promoter for chalky prepainted metal roofs or as a bleed blocker for asphalt roofs.


Metal, asphalt, and spray foam roofs.


  • Reduces asphalt bleed through and improves adhesion of roof coatings to the substrate.
  • Excellent resistance to heat, cold, moisture and weathering.
  • Dark color absorbs the sun’s heat to accelerate the curing process or to increase roof temperature prior to the application of polyurethane foam.
  • Easy to use, non-toxic and VOC-compliant water based primer.


  • Ready to use. Thinning is not necessary. Mix well before using.
  • Roof must be clean, dry and free of any oil, grease, dirt or loosely adhered coating.
  • Bare surfaces must be prepared and checked for compatibility.
  • Follow our roof restoration procedures and always perform an adhesion test.
  • Equipment: brush, roller, spreader or 3000psi, 2gpm airless sprayer with a .017 tip.
  • Do not leave coating in spray guns, hoses and pumps for prolonged periods.
