Sand the metal surface until all existing paint is gone. Clean the surface of dust and other particles with a cloth towel and water.
Buff the target surface for the primer with industrial cleaner and steel wool. Apply the primer to the target surface with either a spray can or a paintbrush. If using water-based paint because of the manufacturer's instruction, use clear sealer to seal the paint after application.
Apply metallic surfacer with a paintbrush evenly over the target surface after the primer has dried. Let the metallic surfacer dry and apply a second coat.
Apply the antiquing solution while the second coat of metallic surfacer is still wet. This allows the antiquing solution to have a chemical reaction with the metal flakes in the metallic surfacer, which creates the patina effect. This reaction will develop over a 10- to 15-minute time span; if the desired effect is reached before the reaction is complete, spray the clear sealer over it to stop the reaction and preserve the appearance.
Things You Will Need
- Cloth towels
- Steel wool
- Industrial strength cleaner
- Primer paint
- Metallic surfacer
- Antiquing solution
- Clear sealer
- Make sure you choose the proper primer paint for the surface you are painting. Read the manufacture's instructions on the label.
- If the antiquing solution turns black when reacting with the metal flakes, paint over it with primer and repeat the process in steps 3 and 4 using a diluted antiquing solution. Mix water with the antiquing solution to dilute it.
