We get calls from homeowners and contractors asking how to properly treat galvanized vents and other flashings before applying our Roofmaster Flashing Paint. Manufacturers of these vents and flashings apply a slick priming oil which prevents the flashings from rusting. Flashing Paint won’t properly adhere to the flashing with the presence of this oil.
There are solvents available on the market for cutting this priming oil, but here’s a quick and cheap tip that most people will already have at home. Make a solution of about 10% vinegar and 90% water, and use this to clean and prep the surface. This cleans and etches the surface of the flashing, which allows for better paint adherence. For extra strong hold, prime the surface first.
