How to remove epoxy resin seams from granite

Countertop installers often use epoxy to join seams between two pieces of granite, to fill in small fissures in the stone or to form a tight seal between a granite countertop and a sink. Epoxy is a two-part adhesive that, when mixed, generally hardens in less than 10 minutes. Once the epoxy cures, it can be a challenge to remove without marring the granite's surface. Special care and a steady hand, however, can often get the job done.

Skill level:

Things you need

  • Single-edged razor blade
  • Protective gloves
  • Acetone
  • Several clean, dry cloths
  • Poultice (optional)

  1. 1

    Use a sharp razor blade to gently scrape away as much of the excess epoxy as possible. Work slowly and carefully.

  2. 2

    Put on gloves and pour a small amount of acetone on a soft, clean cloth. Most nail polish remover contains acetone, so there's no need to make a special trip to the hardware store.

  3. 3

    Rub the affected area until all traces of the epoxy are removed. If necessary, repeat this process, but use only small amounts of acetone each time. Avoid saturating the cloth.

  4. 4

    Use another clean, damp cloth to wipe away the acetone.

  5. 5

    Apply a poultice, if necessary, to remove any stain left behind by the epoxy. Epoxy does not usually stain, but it can darken light-coloured stone. Consult your retailer or stone professional about the appropriate type of poultice for your granite.

Tips and warnings

  • Work in a well-ventilated room.
  • Acetone is highly flammable. Discard the cloths appropriately when the project is done.
  • Avoid using harsh cleaners or steel wool on stone, as they can dull the surface.
