H&B Primer - SA Water-Based Primer for Self Adhering Flashing - 5 Gallon
H&B Primer - SA is a water-based, modified polymer primer specifically designed to promote superior adhesion of Hohmann & Barnard self-adhered flashing membranes. It can be applied to a wide range of substrates, including CMU, plywood, OSB, and glass-faced sheathing. Its milky white formula dries clear and remains permanently pressure-sensitive, strengthening over time for lasting performance. With fast drying times and VOC compliance, this primer supports quick, safe, and reliable installation in both new construction and retrofit applications.
