Gorilla Original Waterproof Polyurethane Glue, 36 oz. Bottle

The Original Gorilla Glue has built a reputation for its incredible, industrial-strength holding power and versatility. Crafted with a water-activated polyurethane formula, this product expands into materials to form an incredibly strong bond to virtually anything, making it the solution for almost any project or repair.

To ensure optimal results, the surfaces must be clean and tight-fitting. Wear gloves to avoid skin contact, as Gorilla Glue can stain skin and ruin clothes.

Directions: 1. Damp It: Gorilla Glue is cured with moisture, so lightly dampen one surface with water. For non-porous surfaces (glass and metal) and dense hardwoods, scratch up the surfaces first and lightly dampen both surfaces prior to gluing. Do not add water to the bottle. 2. Glue It: Spread a thin layer of glue on the other surface. Do not over-apply, as Gorilla Glue will foam 3 to 4 times in volume. 3. Clamp It: Clamp the objects together for 1-2 hours. You can use heavy objects to achieve clamping pressure. The strength of the bond line improves with better clamping, and the full cure takes 24 hours.

Storage: After each use, wipe the nozzle clean with a dry cloth and tightly replace the lid. For bottle sizes 4 oz. and larger, we suggest squeezing out the excess air from the bottle. While still squeezing, tightly replace the cap and then store in a cool, dry place. This helps eliminate moisture in the bottle. Store away from children and animals.

Gorilla Glue will work well on many types of plastic; however, it is not recommended for use on polypropylene (PP) or polyethylene (PE) plastics, or any type of rubber with high oil or plasticizer content.

Visit the Gorilla Store at the top of this page to find more Gorilla Tough products, including a 100% waterproof, solvent-free, one-on-one structural adhesive. This adhesive cures with exposure to moisture in the wood and atmosphere, is stainable and self-spreading, and bonds exotic and common woods, as well as ceramics, plastic, metals, and stone to wood.

Gorilla Glue is unaffected by extreme heat, cold, or water, making it great for indoor and outdoor repairs. It is 100% waterproof and creates an incredibly strong bond to most surfaces, including wood, stone, metal, ceramics, foam, glass, brick, and concrete. The glue expands 3-4 times while penetrating the surfaces for additional strength, and the dried glue is paintable, stainable, and sandable.
