Prepare and Dampen the Surfaces
If you’re using Original Gorilla Glue for the first time, or bonding a new type of material, we always recommend trying a test piece first.
Prepare your 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.
Damp It: 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.
Evenly Apply Gorilla Glue Onto the Dry Surface
Glue It: Carefully apply onto the dry surface. Do not over apply. We recommend wearing gloves or spreading the glue with a disposable brush. In some instances, Gorilla Glue can be a skin sensitizer. If you are predisposed to skin reactions, please take the extra precaution.
If you do get the glue on your skin, try removing it with a dry cloth or paper towel first (particularly if the glue is still tacky). If that doesn’t work, try washing with soap and cold water, or using an exfoliator with a gritty texture. Dry your skin and apply lotion. We do not recommend using any kind of alcohol or acetone. This actually strips the skin of its natural oils, which means the glue is more likely to stick.
Clamp the Two Surfaces Together Tightly
Clamp It: 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. For lighter objects, try using rubber bands to hold the pieces together tightly. Clamp objects for 1–2 hours. For best results, allow 24 hours to cure.
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. Make sure to read and follow directions if using a paint thinner. Always wear gloves. Once the glue is dry, it is best removed mechanically: Try sanding, chiseling, scraping or picking. The dried glue will not damage tools.
After each use, wipe the bottle’s lid and nozzle clean with a dry cloth. For 2 oz. bottles, tightly replace the lid after wiping clean and store in a cool, dry place. For bottle sizes 4 oz. and larger, we suggest squeezing excess air out of the bottle. While still squeezing, tightly replace the cap and then store in a cool, dry place. This helps eliminate moisture in the bottle. You should expect a year shelf life.
Original Gorilla Glue should be clamped for 1–2 hours. During this time, it reaches 80% cure. Allow 24 hours for 100% cure. Note that cure time can vary depending on temperature, humidity and the porosity of the bonding materials.
