The product that started it all. Original Gorilla Glue built a name for itself with its incredible, industrial holding power and versatility. The water activated polyurethane formula expands into materials to form an incredibly strong bond to virtually anything. Gorilla Glue is a 100% waterproof glue, safe for indoor and outdoor use and strong enough to stand up to the elements. Gorilla Glue’s your solution for almost any project or repair. Sand it, paint it, stain it. Simply stated, it’s the Toughest Glue on Planet Earth. Directions: 1. Prepare and Dampen the Surfaces: All surfaces must be clean, dust free and tight fitting. For shiny surfaces, such as metals, glass and some plastics, roughen up the material to give the glue something to bite into. Lightly dampen one surface with water. We recommend using a damp cloth or spraying with water. Do not saturate the surface. For dense hardwoods, lightly dampen both surfaces prior to gluing. 2. Evenly Apply Gorilla Glue Onto the Dry Surface. Carefully apply onto the dry surface. Do not over apply. We recommend wearing gloves or spreading the glue with a disposable brush. 3. Clamp the Two Surfaces Together Tightly. Make sure the clamping pressure is distributed evenly across the surface. Or, if you don’t have a clamp, use heavy objects or Gorilla Tape to achieve the appropriate clamping pressure. Clamp objects for 1–2 hours. For best results, allow 24 hours to cure. 4. Clean up: If you need to remove any uncured “squeeze out” or wet glue, we recommend wiping with a dry cloth or using a standard paint thinner. Once the glue is dry, it is best removed mechanically: Try sanding, chiseling, scraping or picking. 5. Storage Tips: After each use, wipe the bottle’s lid and nozzle clean with a dry cloth. While still squeezing, tightly replace the cap and then store in a cool, dry place. You should expect a year shelf life.
