Polystone, a sculpting material made of epoxy, resin and stone dust, is often used to make collectable sculptural figures, such as comic book, anime or Renaissance sculptures. With proper care, polystone statues can last a lifetime, but the material is softer than solid stone and it breaks more easily than other resins and plastics. In many cases, a broken polystone statue can be repaired at home with materials from the hardware store or home and garden centre.

  1. 1

    Dust the broken pieces with a soft dusting pad. If the pieces are dirty, carefully wipe the broken surfaces with a damp cloth and allow them to dry.

  2. 2

    Apply a few drops of instant bond glue gel to one broken end of the polystone, if it's a clean break. Don't use too much -- use 2 to 3 drops for a 1/2-inch diameter area.

  3. 3

    Hold the two ends of the clean break together until the instant bond glue gel sets, about 30 seconds to 1 minute. When you let it go, it should hold together. Wipe away any excess glue immediately.

  4. 4

    Use two-part epoxy to repair a break that is large or not perfectly clean. Mix the epoxy according to the manufacturer's instructions in a small paper cup. Apply the epoxy with a toothpick and hold the parts together for several minutes until they hold. Smooth the epoxy with a toothpick. Dry overnight before doing any paint touch-ups.

Tips and warnings

  • If necessary, repaint the repaired area with acrylic paints.
  • Use a pair of tweezers to hold very small broken pieces in place.
  • Avoid getting instant bond glue on your skin. If you accidentally bond your fingers, carefully remove the glue with nail polish remover.
