How to Repair Epoxy Paint


You can repair epoxy paint easily but it is hazardous working with epoxy paint. Whether you need to repair deep scratches or peels in the surface or just recoat an area that has worn thin, follow these steps to make sure that the repair is done correctly and safely.

Things You'll Need

  • Dawn dishwashing liquid
  • Ruler
  • Razor blade
  • Portable fan
  • Hair dryer
  • Respirator
  • Paint scraper
  • Epoxy paint
  • Paintbrush
  • Clean around the area of the repair with a mild soap and water mix. A dishwashing soap such as Dawn is best because it will clean and degrease the surface of the paint.

  • Using a ruler and a razor blade, score through the paint at least 2 inches beyond the damaged area to create a square around it. This will allow you to remove the scored area without peeling into the rest of the painted surface.

  • Open all windows or doors in the room to increase ventilation. Set up a portable fan so that it is blowing across (but not directly on) the area you are going to repair. You want to make sure that any fumes generated by the epoxy paint do not have a chance to build up in the room and poison you.

  • Heat the area with a hair dryer. Wear a respirator as you remove and apply epoxy. When the epoxy has softened, starting from the lines you scored and working in toward the center, scrape the paint off with a paint scraper. Make sure all of the epoxy paint is removed in the area you are going to repair.

  • Apply epoxy paint with a paintbrush, working from the center out to the edges. Make sure that you feather the paint over the edges that you scored with the razor blade to blend the old and new areas of epoxy.

Tips & Warnings

  • If the repair is to be made in a highly visible area (like the center of a floor), score and remove a large portion of the paint to avoid the appearance of a small "patch," because there is likely to be a slight difference in color between the old and new paint.
  • Epoxy paint is dangerous because the chemicals in the liquid form work to remove oxygen from the air. You must provide adequate ventilation. Use a respirator and take frequent breaks.
