Gorilla Glue is a water-activated polyurethane formula which expands to materials to form an incredibly strong bond to virtually anything. It easily bonds wood, stone, metal, ceramic, foam, glass, concrete and much more.

Preparation: All surfaces must be clean. Wear gloves to avoid contact with skin. Gorilla Glue will stain skin and ruin clothes.

Damp It: Gorilla glue is activated by moisture. Lightly dampen either surface with water. Do not saturate the surface. Do not add water to bottle.

Glue It: Spread a thin layer of Gorilla glue on either surface. Do not over-apply glue. While curing, glue will expand 3-4 times in size, so be careful of squeeze out.

Clamp It: Grip objects together for 1-2 hours. Use a heavy weight or Gorilla tape to achieve gripping pressure. The bond line improves with better gripping. After each use, wipe nozzle clean with a dry cloth. Squeeze all air from bottle. While still squeezing, tightly replace lid.
