As you may already know, Original Gorilla Glue is a popular adhesive known for its strength and versatility. With its ability to bond various materials such as wood, stone, metal, ceramic, foam, glass, and concrete, it’s no surprise that Gorilla Glue has become a go-to product for many DIY enthusiasts and professionals alike.
One of the more interesting aspects of the Original Gorilla Glue product is that they recommend you use a little water to activate the glue, allow it to expand, and ensure the best results.
But will Original Gorilla Glue work without water?
Gorilla Glue works best when a small amount of moisture is present on the surfaces to be bonded, but interestingly, there is usually sufficient moisture in the air for Gorilla Glue to cure without needing to dampen the materials. In fact, using less water can result in less foaming, which some users find beneficial. For best results overall, lightly dampen the surface you are gluing.
Let’s dive a little deeper into why Original Glue needs water and uncover some helpful tips for getting the best results with it along the way!
Why does Original Gorilla Glue need water to work?
Original Gorilla Glue is a moisture-activated polyurethane adhesive – that is a fancy way of saying that it needs a little water to work properly.
This type of adhesive is known for its versatility, strength, and waterproof properties along with the ability to bond various materials together, such as wood, stone, metal, ceramic, foam, glass, and concrete. One of the key features of Gorilla Glue is that it is 100% waterproof, meaning it can withstand exposure to outdoor elements without breaking down.
The strength of Gorilla Glue comes from its expanding nature. When applied to a surface with moisture present, it activates and expands three times into the materials, creating an incredibly strong bond between them.
Additionally, it is both cold and heat resistant, allowing the bond to hold even through hot and cold temperatures.
The role of water with Original Gorilla Glue
Moisture-activated polyurethane adhesives, often simply referred to as polyurethane adhesives or PURs, require the presence of moisture to initiate and complete their curing process.
Water plays a significant role in the mechanism and properties of these adhesives like Original Gorilla Glue:
- Curing Mechanism: The isocyanate groups present in polyurethane prepolymers react with water to produce a chemical crosslinking reaction. This reaction generates carbon dioxide and leads to the formation of urea linkages, which help in solidifying the adhesive and forming a bond.
- Adhesive Performance: The presence of moisture not only activates the curing process but also helps in achieving the desired properties of the adhesive. When moisture is adequately absorbed, the adhesive can achieve its optimal strength and flexibility.
- Tackiness: Moisture can influence the tack or stickiness of the adhesive. In some formulations, the presence of moisture can increase the tackiness, allowing for better initial bonding.
- Application: When applying moisture-activated polyurethane adhesives, it’s sometimes necessary to introduce a slight amount of moisture (for instance, by lightly misting one of the bonding surfaces) if the environment is too dry. This ensures the adhesive cures properly.
- Environment Sensitivity: The requirement for moisture means that the performance of these adhesives can be affected by environmental conditions. In extremely dry conditions, the adhesive might not cure properly, while in overly humid conditions, too rapid a reaction might occur, leading to bubbles or blisters due to the rapid evolution of carbon dioxide.
- Flexibility: The reaction with moisture often imparts flexibility to the cured adhesive, making it suitable for bonding materials that experience movement or stress.
How to apply Original Gorilla Glue for best results (with water)
When working on a DIY project or repair, it’s important to know how to apply Original Gorilla Glue correctly.
Follow these steps for the best results:
- Prepare the surfaces: Ensure the surfaces you are bonding together are clean, dry, and free of dirt or debris.
- Moisten one surface: Original Gorilla Glue requires moisture to activate curing. While ambient humidity may be sufficient in some cases, it is recommended to dampen one surface lightly with water before applying the glue.
- Apply the glue: Spread a thin layer of Gorilla Glue on the dry surface. Keep in mind, the glue expands 3 times as it cures, so don’t over-apply.
- Press together and clamp: Carefully align the two surfaces and press them together. Use clamps to hold the pieces securely in place during the curing process. The glue sets in about 1-2 hours and fully cures in 24 hours.
- Clean up: To avoid skin irritation, wear gloves during the application. In case of skin contact, wipe off excess glue with a dry cloth and wash the area with soap and cold water.
Applying Gorilla Glue at the proper temperature is essential for the best bond. The ideal application temperature is between 40°F and 100°F (5°C and 38°C) but works best at room temperature.
Note that extreme temperatures can affect the bonding and curing process. With the right application techniques and conditions, Original Gorilla Glue can form a strong bond even without manually adding water.
It can securely bond a variety of materials, making it a versatile choice for various projects.
What if you forgot to dampen before using Gorilla Glue?
If you forgot to dampen the surfaces before using Gorilla Glue (or other similar moisture-activated polyurethane adhesives), you might encounter some issues:
- Slower Curing Time: One of the primary effects of not dampening the surfaces is that the glue may take longer to cure. The moisture in the air can still activate the adhesive, but it’s typically less efficient than directly dampening the surfaces.
- Weaker Bond: The bond strength might be compromised. Moisture activates polyurethane adhesives and helps them expand and penetrate the bonding surfaces. Without sufficient moisture, the adhesive might not penetrate as deeply or expand as much, leading to a potentially weaker bond.
- Incomplete Curing: In very dry conditions, there’s a possibility that the glue might not cure properly or might remain tacky for an extended period.
If you’ve already applied the glue and cannot separate the items without causing damage, you might have to wait and see if the bond is strong enough for your needs. If you can separate the items safely, you can clean off the uncured adhesive, dampen the surfaces, and reapply the glue for optimal bonding.
Does Original Gorilla Glue work on plastic materials?
When it comes to using Original Gorilla Glue on plastic materials, it’s essential to know that it works well on most types, but not all. Specifically, it doesn’t work well on plastics containing polyethylene or polypropylene. These plastics are difficult to bond due to their low surface energy and high resistance to adhesion.
Before applying Gorilla Glue to plastic, ensure the surface is clean, dry, and dust-free. This will help promote a strong bond between the glue and the plastic material. The presence of any plasticizer content could also weaken the bond, as these additives can interfere with adhesion.
Do you really have to wait 24 hours for Original Gorilla Glue to dry?
Setting and curing times are essential when using Gorilla Glue. In about 1-2 hours, the glue will begin to set, allowing you to reposition and adjust the bonded materials as needed. However, achieving full strength and maximum bond requires waiting up to 24 hours.
It is worth noting that Gorilla Glue is 100% waterproof and can handle exposure to moisture without having the adhesive bond fall apart. But remember, this is only applicable after the glue has fully dried and cured.
How Original Gorilla Glue bonds on different surfaces
Gorilla Glue is a versatile adhesive designed to work on various surfaces, making it ideal for numerous projects. Before you start, make sure the surfaces are clean and free of dust, grease, or oil to ensure better adhesion.
Gorilla Glue works well with porous surfaces like wood, providing strong bonds between dense hardwoods as well as softer woods. Remember to dampen the wood slightly with a cloth before applying the glue.
Metal and Ceramic
These non-porous surfaces require a small amount of moisture to ensure the glue cures correctly. Lightly mist the metal or ceramic surface, apply the glue, and hold the pieces together until the bond is secure.
