Gorilla Glue is the strongest and most versatile glue on the market today. We do everything technically possible to make our glue the finest, strongest and most pure adhesive in the world. It takes just an ounce of Gorilla Glue to cover one square foot. That's 3 to 4 times the coverage of other glue. In addition to being 100% Waterproof, incredibly strong Gorilla Glue bonds wood, stone, metal, ceramics, Corian®, styrofoam and more. Remember that this glue will foam 3 to 4 times its applied size, so a little goes a long way.
