Stripping Paint? Beware the Lead Hazard

Posted on July 23rd, 2024

The Silent Strip Paint Remover infrared heat gun in use at my place. It softens paint at low enough temperature that lead is not vapourized into a harmful gas.

Q: I’m stripping lead paint from a bunch of wood trim and doors, and I need some advice. I’ve tried different chemical strippers with no success, but have found that a heat gun works. It’s very slow, but most importantly I have concerns about my health. Is it okay to strip lead paint with a heat gun? What other options are practical?

A: I’m glad you wrote, because using a heat gun on lead paint is dangerous. The lead compound in the coating vapourizes at temperatures higher than 700F, entering your body through your lungs. Don’t ever strip lead paint with any kind of torch or high-temperature device.

A safer thermal option for softening paint is heat delivered by infrared radiation. An electric device I’ve used called Silent Paint Remover raises the surface temperature of painted wood to 300F to 400F, softening old coatings and window putty in the process, but leaving lead in solid form.

Have you tried either one of two chemical products called Citristrip or Organistrip? Both are safe and work very well in my experience, even on old, multi-layer paint.

You’ll find a set of curved cabinet scrapers a big help, especially for cleaning the concave areas of your trim regardless of how you soften the paint. The right kind of scrapers can reduce the time it takes to strip surfaces by at least 50%. You’ll find them at specialty woodworking supply outlets.
