Two part epoxy resin is used when you want to permanently attach two objects. Unfortunately, occasional mistakes can make you wish that epoxy wasn’t quite so permanent. If you realize your mistake within 48 hours of applying the epoxy resin, you may be able to dissolve it. Of course, the sooner you attempt to correct your mistake and remove the epoxy, the greater the chance that you will be successful. Older epoxy may not dissolve at all, but you can definitely try this method and hope for the best.
Once you know how to remove two part epoxy resin, you may want to keep the materials needed to complete the job on hand. That way, when working with epoxy, you know you can conduct a fast clean up to repair any mistakes as necessary.
Step 1: Generously apply paint thinner to a clean rag and place it over the epoxy. Wait 5 minutes before proceeding.
Step 2: Touch the two part epoxy to see if it has softened. If it has, you can try removing the softened bits with a putty knife. Use a plastic putty knife if you are working with wood or plastics: stronger materials that are less likely to scratch may be able to withstand a metal putty knife. If the two part epoxy has not softened, apply the soaked rag for another 10 minutes, then try again.
TIP: If 20 minutes of soaking the area with paint thinner does not make the epoxy any softer, chances are the epoxy has already completely cured. You won’t be able to dissolve the resin away: you can try a dremel with a bit to cut away the bits of epoxy and separate the two objects that were glued together.
Step 3: Soak the rag again with paint thinner and place it over the epoxy once you hit hard epoxy. Allow it to sit on the epoxy until it softens, then remove what you can with your putty knife. Continue until you have removed as much of the resin as possible.
Step 4: Dry the area with a rag, removing any of the paint thinner residue. Clean the putty knife and carefully discard the rag saturated with paint thinner.
