Instructions
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.
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.
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.
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.
