  • PVA Glue (Polyvinyl Acetate): Commonly used for woodworking, easily cleaned with water when wet.
  • Polyurethane Glue: Strong and waterproof, requires solvents for removal.
  • Hide Glue: Made from animal collagen, can be softened with heat and moisture.
  • Epoxy: A two-part adhesive that is very durable, often requiring sanding or chemical removers.

Removing Wet Wood Glue

If the glue is still wet, it is significantly easier to remove. Follow these steps:

  1. Blot Excess Glue: Use a clean cloth or paper towel to gently blot up the excess glue.
  2. Use Water: For PVA glue, dampen a cloth with warm water and wipe the area.
  3. Scrape Gently: If necessary, use a plastic scraper or putty knife to remove any remaining glue without damaging the wood surface.

Removing Dried Wood Glue

Dried glue removal can be more challenging and may require specific techniques based on the glue type:

  • PVA Glue:
  • Soak a cloth in warm water and place it over the glue to soften it.
  • Once softened, scrape it away gently.
  • Polyurethane Glue:
  • Use a solvent like acetone or denatured alcohol.
  • Apply a small amount to a cloth, and dab on the glue until it begins to dissolve.
  • Scrape off the residue.
  • Hide Glue:
  • Apply heat using a heat gun or hairdryer to soften the glue.
  • Wipe away the softened glue with a damp cloth.
  • Epoxy:
  • Mechanical methods such as sanding may be necessary.
  • Alternatively, use a commercial epoxy remover following the manufacturer’s instructions.
