BONDS DISSIMILAR MATERIALS: Gorilla Glue is the incredibly strong all-purpose adhesive that expands into all kinds of materials to create a strong, durable bond. It bonds stone, metal, glass, ceramic wood & more. EXPANDING FORMULA: Gorilla Glue expands 3 x into the materials to form an incredibly strong bond. It also is 100% waterproof and can withstand extreme temperatures (-40°C to 100°C), making it suitable for indoor and outdoor applications. DAMP IT: Gorilla Glue is activated by moisture. Lightly dampen one surface with water. Do not add water to bottle. For dense hardwoods – dampen both surfaces GLUE IT: Spread a thin layer of Gorilla Glue on the other surface. Best results achieved when applied at room temperature. Note: Do not over apply glue as it will expand 3-4 times whilst curing. Be careful of squeeze-out. GRIP IT: Grip objects together for a minimum of 1-2 hours. You can use clamps, heavy objects, or Gorilla Tape to achieve gripping pressure. Bond line improves with better gripping. Full cure achieved in 24 hours.
