How to Remove Paint from Metal

Some painting projects require a little preparation. Refurbishing an old fence or outdoor metal furniture sometimes requires stripping old paint from metal.

If you have concerns about stripping metal, you’re not alone. Most people do not know how to strip paint from metal without scratching the underlying substrate.

Before you attempt to sand paint off metal, consider that different types of metal have different processes for safely removing paint. It’s also important to determine whether the coating needs to be partially removed or completely stripped away.


Ready to Learn How to Remove Paint from Metal?

The best way to remove paint from metal depends on the condition of the metal you’re working with and your project goals.

Your approach to stripping paint from metal depends on what you aim to accomplish:

  • Goal 1: You want to remove a little paint that got on the metal.
  • Goal 2: You want to repaint a previously painted metal piece that is in decent condition.
  • Goal 3: You want to strip all the paint from the metal.

If you want to remove a lot of paint completely, we recommend hiring a professional.

Read on to learn how to remove paint from metal to achieve each of these goals—and use our tips and tricks to help make your project a success.

Goal 1: Removing Paint from Metal

If a few specks of errant paint landed on a piece of ferrous or non-ferrous metal, don’t worry. You can remove that bit of paint from metal pretty easily.

Sanding paint off metal might strip away the coating, but doing so risks scratching the substrate, depending on the type of metal.

To remove an oil-based or alkyd paint, scrub it with a wire brush. If the paint is acrylic, use denatured alcohol and a wire brush. When using alcohol, be sure to follow all safety recommendations.

If you’re trying to remove paint from aluminum, brush gently with a stainless-steel wire brush, being very careful not to scratch the surface.

Rinse the metal with water, then seal the entire piece with a coat of the appropriate metal primer.

Goal 2: Getting Paint Off Metal That Is in Decent Condition

Good news: If the metal is not rusted, there is no need to strip off the paint. You can simply paint over the existing coating.

Make sure the surface is clean, dull, and dry before you start painting. You may want to sand the old paint down a bit for a smooth finish.

If sanding is necessary to smooth the painted metal surface, use 180- to 220-grit sandpaper and a sanding sponge for non-ferrous metal (like aluminum) or 80-grit sandpaper for ferrous metal (like steel or iron). Be sure to sand aluminum gently, as it’s easily scratched. When using sandpaper, be sure to exercise safety measures, including but not limited to protection for your eyes and respiratory system.

When the surface is clean, dull, and dry, it’s time to paint the metal. Apply an even coat of High Performance Acrylic D.T.M, which is easy to apply and can be tinted to any of Benjamin Moore’s 3,500+ colours. Allow the paint to dry completely.

Goal 3: Completely Stripping Paint from Metal

Removing a significant amount of paint from metal is a time-consuming and potentially dangerous job. We strongly recommend hiring a professional.

If you’re determined on stripping paint from metal yourself, consult your locally owned Benjamin Moore store for advice on the best chemical paint stripper and other tips for doing the job properly and safely.

Using a chemical paint stripper on your own may not achieve your desired result—and as mentioned, it takes a lot of time and can be hazardous. If you choose to do it yourself, be sure to read the label very carefully and follow all safety recommendations.
