How Do You Remove Paint From Fiberglass?

Paint stripper can be used on fiberglass, but it can't be allowed to sit too long or will start to eat through the fiberglass. It is best to look for a mild paint stripper and only leave it on the fiberglass for a few minutes at a time.

Be sure to have all tools and cleaning supplies handy before stripping the paint.

  1. Prepare the workspace
  2. Spread out a drop cloth outside or in a well-ventilated area. Paint stripper vapors can be quite toxic, so it is essential to have plenty of fresh air. Put on durable rubber gloves, goggles and a respirator mask.
  3. Apply the paint stripper
  4. Use a paintbrush to apply a thick coat of paint stripper over a small section of fiberglass. It is best to work in sections since the stripper should only be on the fiberglass for a short period of time before removal. Allow the paint stripper to sit for two to three minutes.
  5. Remove the paint
  6. Use a scraper to scrape up the softened paint from the fiberglass surface. Do this with rubber gloves and other safety gear still on. A small nylon brush or abrasive pad works well to remove paint from nooks and crannies.
  7. Neutralize remaining paint stripper
  8. Wipe the fiberglass surface with a cleaning pad dipped in denatured alcohol to neutralize the paint stripper. Take a clean rag and wipe the surface to remove paint and stripper until it no longer picks up color from the fiberglass surface. Use more denatured alcohol as needed.
