Wipe the galvanized surface down with white vinegar.


Safe way to cleanWhen coating new galvanized metal substrates make sure that the surface is properly prepped.  Here is one way: Go over the metal with a wire brush to remove any oxidation. Wipe the galvanized surface down with white vinegar. The vinegar is a mild acid which acts to etch the galvanized coating so the paint will stick. Prime the surface with a primer made for metal.  Do not use alkyd base primers or topcoats direct to a galvanized surface.  Prime with Forrest’s 95-J-100 water base primer and topcoat with Forrest’s 4300 or 3300 100% acrylic topcoat.
