How To Apply Gorilla Glue On Metal

You can combine metal with the same material or distinct objects such as velcro, glass, or wood, to name a few. But, regardless of which pair, follow this easy-to-follow procedure.

1. Spray Water On The Surface

Clean the objects you will bond together with Gorilla Glue. Then roughen the surfaces of both objects using sandpaper.

Finally, you should dampen the surface with water because the glue has a water-activated formula. But make sure it isn't too watery. This part prepares the exterior for the next steps, allowing the glue to stick well.

2. Squeeze Out A Layer Of Glue

As a rule of thumb, cover one square foot with 1/2 ounce. Spread it evenly into the metal using a disposable stick or brush.

3. Clamp The Two Surfaces Together

Use a metal clamp or heavy objects to put pressure. For lighter items, rubber bands are enough to hold the metal and the other object jointly. Secure them for one to two hours.

What Is Gorilla Glue?

This product is a polyurethane adhesive that was first introduced in the early 1990s. Whether for repair or DIY home projects, it is not only widely used in the U.S. but also around the globe. Like other products, it comes with advantages and disadvantages.

Advantages

Below is a list of benefits you can get when you use Gorilla Glue.

  • Waterproof
  • Durable
  • Suitable for indoor and outdoor surfaces
  • Resists extreme temperatures
  • Practical for bonding to different materials
  • Offers grip time within an hour after application

Disadvantages

While Gorilla Glue is suitable for all materials, it's not ideal for some plastics such as polyethylene (packaging films and bottles), polypropylene (bins and crates), and high-oil rubbers. They do not attach well because they do not create a bond between adhesive and water ions.  

Moreover, Gorilla Glue contains toxic elements, making it a health hazard.

Is Gorilla Glue Toxic To Humans?

Gorilla Glue is harmful and deadly when ingested, inhaled, or touched to a certain degree. If your eyes or skin are contaminated, rinse them with running water for several minutes and contact a medical professional. 

It also triggers difficulty breathing and respiratory problems if you inhale the glue for an extended period. Similarly, regular use of this product can induce organ damage in its frequent users.

Here are a few safety measures you must follow while using Gorilla Glue:

  • Wear rubber gloves and goggles.
  • Avoid contact with your skin and eyes.
  • Work in a well-ventilated area.
  • Clean the work area immediately, especially any excess glue.
  • Sanitize your hands and exposed skin after application.
  • Store it away from sunlight and prevent it from freezing.

What Are The Types of Gorilla Glue?

Several varieties of Gorilla Glue have been developed and are now available, from the original to the white version.

Original 

This tan glue is compatible with wood, glass, foam, and metal. Aside from the mentioned advantages, it allows surface sanding, staining, and oil-based painting after drying. 

Because people use it for various purposes, you can select from a wide range of bottle sizes. These include 2 to 36 ounces and 3 grams.

White

This expandable glue dries white, giving a more subtle residue. It is almost identical to the original one, except for the drying time. The manufacturer shortens it roughly by half

For this formula, you can opt for a precision pen or a 2-ounce bottle.

Clear

Unlike the original, this clear variant is a non-foaming hybrid. Given its crystal clear appearance, the bonded metal will sustain its surface without visible marks.

The improved formula works for minimal gap filling. However, it remains incompatible with certain plastics similar to previous types. It cannot also withstand prolonged moisture exposure.

Moreover, a prestigious museum discovered that it tarnishes metal coupons based on an executed test. The available sizes range from 1.75 ounces to 3 grams. For easy and accurate dispensing, consider the Micro Precise.

How Long Does Gorilla Glue Take To Dry On Metal?

The original Gorilla Glue application takes around 20 minutes, whereas the glue sets after one to four hours. Meanwhile, curing requires a longer duration. For full strength, wait for one day to cure.

Temperature and humidity affect the drying phase. Thus, the ideal curing temperature is between 40 and 200 degrees Fahrenheit. It will fluctuate depending on the variant used.

Note that the Gorilla products have varying drying times. Others need less time to set on metal, such as the Gorilla Epoxy, Gorillaweld, and Gorilla Super Glue.
