Product Information

Full details

This guide is for anyone tackling demanding repairs or projects, from DIY enthusiasts to professionals, who need an incredibly strong and durable adhesive. Gorilla Glue stands out for its 100% waterproof and temperature-resistant bond, achieved by its unique water-activated polyurethane formula that expands into materials. A key consideration for optimal strength is the requirement to grip bonded objects together for 1-2 hours during the initial curing phase.

FAQs

Is Gorilla Glue truly 100% waterproof?

Yes, once fully cured (after 24 hours), Gorilla Glue forms a 100% waterproof bond, making it suitable for both indoor and outdoor applications.

Why does Gorilla Glue expand when it cures?

Gorilla Glue is a polyurethane formula activated by moisture. This reaction causes it to expand, allowing it to penetrate and fill voids within materials for a stronger mechanical bond.

How long do I need to clamp or grip materials?

For an incredibly strong bond, objects should be gripped together for 1-2 hours. This sustained pressure is crucial during the initial curing phase.

How long does it take for Gorilla Glue to fully cure?

While an initial bond is formed within 1-2 hours with gripping, Gorilla Glue achieves its full strength and maximum cure in 24 hours.

Can I use Gorilla Glue on plastics?

Gorilla Glue bonds to many plastics. However, due to the wide variety of plastic types, it's always recommended to test it on a small, inconspicuous area first.

What if I get Gorilla Glue on my clothes or skin?

On skin, wash immediately with soap and water. For cured glue, try warm water and abrasive soap. For clothes, it is very difficult to remove once cured; try scraping or using mineral spirits before it fully cures.

Do I need to add water for it to work?

Gorilla Glue is water-activated. For best results on dry materials, lightly dampen one surface to provide the necessary moisture. On naturally moist materials, no additional water is needed. Do not over-wet.

Troubleshooting

Glue doesn't seem to be curing or bonding strongly.

Ensure surfaces were clean and dry. Lightly dampen one surface to activate the water-activated formula. Most importantly, ensure consistent gripping pressure was applied for the full 1-2 hours.

Gorilla Glue got on my skin.

Immediately wash with soap and water. If cured, try scrubbing gently with an abrasive soap and warm water, or use a petroleum-based product like mineral spirits. Do not use acetone, which can cause further bonding to skin.

Too much glue foamed out of the joint.

This is common due to its expansive nature. Wipe away excess foam with a dry cloth while wet. Once cured, carefully trim or sand the excess with a razor or sandpaper.

Bond fails under temperature extremes or water exposure.

Ensure the glue had a full 24 hours to cure before exposure to extreme conditions. Also, confirm surfaces were prepared correctly and proper gripping pressure was applied during the initial cure.

Pros and Cons

Pros

  • Exceptional bond strength on diverse materials.
  • Completely waterproof, suitable for outdoor and marine applications.
  • Resistant to extreme temperature fluctuations.
  • Expansive action fills voids and creates a deeper mechanical lock.
  • Reliable for challenging and heavy-duty repairs.

Cons

  • Requires 1-2 hours of sustained gripping or clamping pressure.
  • Full cure takes 24 hours, meaning immediate use is not possible.
  • Expands during curing, potentially creating foam that may need trimming if too much glue is used.
  • Requires gloves during application to avoid contact with skin, as it is difficult to remove once cured.
  • Requires clean surfaces for optimal adhesion, adding a preparation step.

Setup, Compatibility & Care

Preparation:

  1. Clean Surfaces: Ensure all surfaces to be bonded are thoroughly clean, free from dirt, dust, grease, and loose particles. A clean surface is essential for optimal adhesion.
  2. Moisten (Optional but Recommended): Gorilla Glue is water-activated. For best results on dry materials, lightly dampen *one* of the surfaces with a small amount of water. Do not over-wet. This helps initiate the expansion and curing process.
  3. Wear Gloves: Always wear gloves to protect your skin. Gorilla Glue is very difficult to remove once it dries on skin.

Application:

  1. Apply Glue: Apply a thin, even layer of Gorilla Glue to one of the surfaces. A little goes a long way, as the glue expands.
  2. Join Surfaces: Press the two surfaces together firmly.
  3. Grip/Clamp: Crucially, grip the bonded objects together for 1-2 hours. Use clamps, heavy objects, or strong adhesive tape (like Gorilla Tape®) to maintain constant pressure. This ensures the expanding glue forms the strongest possible bond by maximizing surface contact.

Curing & Full Strength:

  • Initial Bond: Achieved after 1-2 hours of gripping.
  • Full Cure: The adhesive reaches its maximum strength and water resistance after 24 hours. Avoid subjecting the bond to stress or moisture until fully cured.

Compatibility:

Gorilla Glue is highly versatile and bonds to a wide array of materials, including:

  • Wood
  • Stone
  • Metal
  • Ceramics
  • Foam
  • Glass
  • Some plastics (test a small, inconspicuous area first, as not all plastics are compatible)

Care & Storage:

  • Clean Up: While wet, remove excess glue with a dry cloth or paint thinner. Once cured, it can be carefully scraped or sanded.
  • Storage: Store the bottle in a cool, dry place with the lid tightly sealed to prevent the glue from curing in the bottle. Avoid exposure to moisture or high humidity.
