Expert Verdict — Reviewed by the SuperArbor Pro Desk
Always prime before applying self-adhesive vapor barrier membranes; adhesion over unprimed concrete or gypsum decks is the most common failure point. Use this system-matched Duro-Last primer rather than a generic one to keep the assembly within the manufacturer's system requirements. Work in dry conditions and let the primer flash off before unrolling the DL VB.
Follow the primer's safety data sheet for ventilation, skin protection and flammability precautions during application on the roof.
