Applying metallic paint to steel in the main requires the same preparation and application as painting any metal object, although as a general rule it is best to use oil-based paint on steel. One of the main advantages of using oil based paint is it keeps rust from forming.
Before selecting metal paint at your local paint shop there are several basic steps you will need to follow before applying it.
1. The first step is to thoroughly wipe down the metal with a wet clean cloth to remove any sign of dirt, grime, oil, cobwebs etc.
2. If the steel surface shows any sign of surface rust then either a stiff wire brush or steel wool needs to be used to sand the rusted area smooth.
3. Use a clean cloth or brush to take away any dust particles and grit from the sanded area.
4. Use an oil-based metal primer to seal the newly sanded area to prevent any rust from reforming and allow plenty of time for the primer to dry.
5. To ensure the metal paint you intend to use bonds properly to the steel surface it is advisable to use the metal primer to paint the entire steel surface of the object to be painted.
6. Use a good quality paint brush or if there is a big area or object to paint such as a steel shed use a roller to create a smooth finish.
7. An airless sprayer is another effective method that can be used to apply oil-based paint.
8. Using oil-based paints means any brush or other equipment that comes in contact with it will need to be cleaned with turpentine so ensure you have a supply handy.
9. An airless sprayer is ideal for large paint jobs and can in some cases be hired from a Hire Store on a daily or an hourly basis. However, you will need to ensure if a sprayer is hired it is returned in the condition you received it at the time of hiring.
10. Use a dry clean cloth to wipe off any over spray or paint drips.
