Quick-drying, one-part, moisture-curing primer.
It is used as an adhesion promoter for Vulkem brand urethane sealants and coatings and TREMproof membranes on porous surfaces such as concrete and wood.
Apply generously with a clean brush or roller. Do not apply in excess where it will puddle or pond. At 70 °F (21˚C), allow 30 to 45 min for primer to become tacky before applying sealant, coating or membrane.
