There is a variety of methods for removing epoxy adhesives; we’ve collected a few methods we prefer here.
Removing uncured epoxy: Uncured epoxy is removed similarly as you would clean spilled resin.
Option 1:
- Follow all safety warnings on adhesives and solvents, and provide adequate ventilation.
- Scrape as much material as possible from the surface using a stiff metal or plastic scraper.
- Optional but helpful, warm the epoxy to lower its viscosity/making it thinner and more runny.
- Clean the residue with lacquer thinner, acetone, or alcohol.
- For Wood: After applying wood surfaces with epoxy, it's a good idea to brush the wet epoxy (in the direction of the grain) with a wire brush to improve adhesion. Allow solvents to dry before recoating

Option 2:
Isopropyl alcohol or acetone: You can use isopropyl alcohol (rubbing alcohol) or acetone to remove any uncured epoxy adhesive. "Uncured" refers to the stage wherein the adhesive is not yet fully set, and is either still in its liquid or gel state, or could also be hard to the touch, but not yet fully set (typically epoxy takes 24 to 48 hours to fully cure or set).
