Dutch Boy® Red Oxide Primer prevents rust formation when applied onto interior and exterior steel and iron surfaces. It is best suited for industries where there is an immediate need to prolong the life of metal products.
SURFACE PREPARATION: Metal Surfaces Wipe the surface with a rag soaked in paint thinner to remove grease, oil, wax and other foreign matter. For new, galvanized surfaces, etch the surface by applying a metal etching solution. Rinse with water and dry immediately.
Unpainted galvanized surfaces that have been exposed for 6 months or more need not be etched.
For recoating pre-painted galvanized surfaces in good condition, sand lightly wipe the surface with a clean rag before applying paint. Remove all loose paint film to sound surface. Spot prime bare substrate.
For corroded galvanized surfaces, remove rust by wire brushing and use a metal etching solution. Let it stay for 10-15 minutes. Be sure to wash surface thoroughly with water and solvent wipe to dry. Immediately prime after drying.
