Before applying Rust-Mort, which contains acid, review the material safety data sheet from the company for an overview of safe handling.
Things You Will Need
-
Rub the rusted area with a wire brush to remove loose rust. Do not try to remove all the rust; some rust is necessary for the product to work effectively.
-
Wear protective gloves and a face mask. This product contains phosphoric acid, which is caustic.
-
Dip a clean, wide paintbrush into the Rust-Mort and allow excess to drain back into the can.
-
Apply a thin coat of the product on rusted areas, distributing it evenly. Repeat the application to add three or four thin coats, rather than one thick coat.
-
Allow the surface to dry for at least 24 hours.
-
Dampen a cloth and wipe the surface to remove any residue. Allow the surface to completely dry before applying primer or paint.
