I have a poor track record of success in painting galvanized substrates. What am I doing wrong?
Painting galvanized steel, like many other metal substrates, has its own set of “do’s and don’ts” for ensuring a long-lasting paint job. Galvanized metal comes from the factory with a thin layer of oil to prevent white rust. Painting over this oil usually results in paint failure. Alkyd paints applied to galvanized metal produce an acceptable paint film initially, but will quickly fail. And when galvanized metal is allowed to remain exposed to the atmosphere, it will oxidize, producing a poor surface for coating adhesion.
