The product that started it all. Original Gorilla Glue built a name for itself with its incredible, industrial holding power and versatility. Water activated, it expands into materials to form an incredibly strong bond to virtually anything. Gorilla Glue is your solution for almost any project or repair. It’s 100% waterproof, safe for indoor and outdoor use and strong enough to stand up to the elements. Plus, its expansion allows it to penetrate the glued surface for a superior bond. Sand it, paint it, stain it. Simply stated, it’s the Toughest Glue on Planet Earth.

Directions
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.

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. 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.

Storage Tips
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.

What is the temperature range for applying the glue?
For best results, apply the glue at room temperature.

Original Gorilla Glue should be left out of reach of children and animals.

Can you speed up the curing process?
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.

Is Gorilla Glue truly 100% waterproof?
Yes. Gorilla Glue is 100% waterproof. It passes ANSI/HPVA Types I and II.

How do I extend the shelf life of Gorilla Glue?
Gorilla Glue is moisture activated. Once the adhesive comes in contact with moisture, it can start to harden. To extend the shelf life, always wipe lid and nozzle clean with a dry cloth and tightly replace the lid.

My bottle of glue has formed a dry layer on top; can I still use it?
Any glue that is still in liquid form is perfectly usable and reliable. If the dry layer is very thin, use a pointed tool to poke through it and carefully pull the dry layer through the cap.
Do not microwave or heat your bottle of Gorilla Glue to soften the top layer.

How do I clean up Gorilla Glue?
Wipe off excess glue immediately with a dry cloth or standard paint thinner. Do not drag glue over material; instead, make small swipes to remove wet adhesive. Make sure you avoid skin contact. Cured glue can be removed with a chisel, scraper or sandpaper

What is the proper clamp time?
When using Original Gorilla Glue, clamp objects for 1–2 hours. For best results, leave overnight.

What if I don’t have clamps?
Gorilla Glue expands as it cures. To ensure the strongest bond, clamping pressure is needed. There are many different ways to clamp the surfaces, but keep in mind the stronger the pressure, the better the bond will be. Professional clamps are ideal, but if those aren’t handy, you can use heavy weight from bricks, books or even Gorilla Tape. The key is to ensure a tight-fitting glue line by applying even distribution of pressure.

How much Gorilla Glue should I apply?
Apply a thin layer of glue. A little bit goes a long way. As a general guide, use a ½ ounce per square foot. Be careful of uncured “squeeze-out” or wet glue, particularly on finished furniture. If you need to remove any squeeze-out, we recommend wiping with a dry cloth or using a standard paint thinner. Make sure you use the solvent with care in a well-ventilated area. 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.

Why do I need to add moisture before gluing with Gorilla Glue?
Gorilla Glue is moisture activated—this is what causes the chemical reaction in polyurethane adhesives. Therefore, you need to apply a small amount of moisture to one surface. Then apply glue to the dry surface and clamp. For dense hardwoods, lightly dampen both surfaces prior to gluing.

Do I need to prepare the surface first?
Make sure surfaces are clean and tight fitting. For smooth, shiny surfaces, such as metal and plastic, adhesion can be increased by sanding or abrading the surface. This gives Gorilla Glue more surface area to grip.

Is Gorilla Glue really for the Toughest Jobs on Planet Earth?
Gorilla Glue is an all-purpose adhesive. If used correctly, it will bond just about anything and for just about forever. It is free of solvents and fillers, which makes it strong and versatile. There are some surfaces and materials that are difficult to glue, such as certain plastics. Aside from a few of these materials, we are certain Gorilla Glue offers an extraordinary, waterproof bond on just about anything.
