How to Remove Two Part Epoxy

Two-part epoxy forms a strong bond that has low shrinkage and seals water out of surfaces and joints. Woodworkers use epoxy in joints to hold a project together permanently with great strength. Fiberglass boat repairs use layers of epoxy and fiberglass cloth to seal cracks and fill in holes that are water-tight. Permanent adhesives are easier to remove before they dry, but with the right tools you can remove cured two-part epoxy also.

Instructions

    • 1

      Put on gloves to protect your hands from the epoxy.

    • 2

      Place a paint scraper on the surface at a 45-degree angle. Push the scraper down the length of the wet epoxy to remove it.

    • 3

      Clean the paint scraper with lacquer thinner to remove it from the scraper before it dries. Pour lacquer thinner on a shop cloth and rub it on the surface to remove any small traces of the epoxy.

    Cured Epoxy

      Put on gloves to protect your hands.

      Squeeze the trigger on a heat gun and direct the tip on one edge of the epoxy. Heat the cured adhesive until a paint scraper will push through it. If there is fiberglass cloth on top of the epoxy, heat the area and then pull the cloth up with a pair of pliers. Work in one direction with the heat gun ahead of the pliers to soften the epoxy until the fiberglass cloth is removed.
