What Are the Best Methods for Painting Galvanized Steel?
Galvanized steel is one of the most durable metals on the market and is used for everything from industrial structures to playground swing sets. One of its major drawbacks, however, is its susceptibility to corrosion. Luckily, properly cleaning and painting galvanized steel will keep the metal from wearing down. Professionals utilize three different methods when applying corrosion protection to steel: spray painting, hand painting and powder coating. Before a drop of paint is applied in any form, each steel surface must be properly cleaned. The first step, no matter if the metal is corroded or brand new, is to sand it with a thick-grit sandpaper. Apply pressure until any bumps or irregularities are removed. Next, clean the entire surface with soapy water and rinse, letting the metal completely dry. Finally, purchase a galvanized metal primer and apply it to the entire surface.
