The Best Way to Remove Paint From Metal

Metal is unsuitable for paint adhesion, easing the removal process.

Unlike wood, metal is a non-porous surface, making it unsuitable for paint adhesion. If you must remove paint from metal, this quality greatly enhances your odds of success. In addition, because metal is hard and durable, it allows for more aggressive removal techniques that might damage more sensitive surfaces. Still, before you start, know the appropriate materials to use and the proper ways to employ them, or you could accidentally damage the metal and surrounding surfaces.

Things You'll Need

• Plastic dropcloths
• Heavy-duty fabric dropcloths
• Paint stripper
• 3- to 4-inch oil-based paintbrush
• Plastic putty knife

Instructions

1. Cover the flooring below the metal with plastic dropcloths. Cover the plastic dropcloths with fabric dropcloths.

2. Brush on a thin coat of paint stripper, using a 3- to 4-inch oil-based paintbrush. Allow the paint stripper to sit on the metal for five minutes.

3. Scrape away the paint, using a plastic putty knife.

Tips & Warnings

• If you need to remove minor drips and splatters from metal, first apply lacquer thinner to the blemishes, and then scrape them free with a plastic putty knife.

• If you do not plan to repaint the metal and are worried about scratching the surface, use a rag as a buffer between the scraper and the paint.

• Paint thinner will cause the old paint to liquefy. Do not use a plastic dropcloth by itself as drips will pool up and lead to unforeseen messes. In addition, drips may bleed through fabric dropcloths. Use both types of coverings together, or you may stain underlying surfaces.
