Best Metal Adhesive Buying Guide
How to Choose the Best Glue for Metal
Choosing the best adhesive for metal among thousands of choices is not an easy task, especially when you don’t know what to expect from the products. To give you an understanding of this, we are sharing with you the exact method by which we have picked the top 10 metal adhesives.
1. Bond Time
The amount of time needed for the glue to attach two metal surfaces firmly is the first thing you need to consider when buying glues for metal. For precise crafting works or repair, you must get a glue that can give you a permanent adhesion within minutes. Otherwise, it will be difficult to leave the materials attached for a long time without moving them. That’s why the more time it requires to bind two surfaces, the more is the risk of having a weak bond.
If you have plain surfaces to fix with the glue, you can skip the bonding time over the other features. But we recommend fast-setting glues for the best result.
2. Challenge to Come
Metal products are meant to be durable and strong. They absorb a lot of pressure than the other weak adhesives. When setting metal pieces with glue, you need to check how much pressure the cured glue can take before giving up. So, get a product that can withstand a good amount of vibrational and tensional force.
3. Chemical Resistance
Different chemicals interact differently with other chemicals. When it comes to glues, there are a lot of chemicals that eliminate adhesion. For choosing glue for metal, it is a must to check which chemical can cause a problem and which not. Knowing this will help you get a product for your specific problem.
4. Amount Needed
This is another factor to consider when purchasing metal glues. You can’t use a lot of glue for crafting or precise repair works. So, the less amount needed, the better. You will see a lot of cheap metal glues in the market that requires you to put a lot of amounts to get good adhesion. Eventually, you end up spending more than the high-end glues that can fix metal surfaces with a few drops.
5. Ease of Use
An easy to use product is always preferable over hard to use products. In metal glues, it is a great concern. If you mess up with the glue when application, it can ruin your cloth and materials you were repairing. Some adhesives are made with harsh chemicals that can cause harm to human skin. For example, spitting epoxy glues in soft plastic or fabric will damage the material almost instantly.
So, go for a product that can be applied easily without any complication. Different brands nowadays use newer technologies to give the user a smooth glue applying experience. So, check what you are getting.
6. Surface Type
Some adhesives are great for using on the smooth surface where some are great in the porous surface. When purchasing a metal adhesive, it is mandatory to check on what surfaces it works best. You’ll find some high-quality adhesives that can be applied on any type of surface. If you have a good budget, go for those options. It pays off.
7. Temperature Tolerance
Resilience to temperature fluctuations is mandatory for strong bonding. The world constantly moving and the temperature fluctuates so often here. If your product can’t hold a strong bond in a particular season, it will eventually weaken. See whether the product can withstand heat and cold temperatures as well as resistant to moisture.
8. Final Color
When you are repairing your favorite toy or a showpiece, it is necessary to get an invisible metal glue so that the repair goes unnoticed to the visitors. We have reviewed some transparent adhesives that can do this best.
If you pick a glue that cures in a different color, make sure it is sandable and paintable. So that you can give the surface the exact color you want.
9. Safety Issue
As you already know that glues are made with chemicals and some of them can be toxic. To ensure a safe working environment, you need to check the material by which the glue has been made. Some highly adhesive glues require you to wear safety goggles and respiratory masks for safety. If you want welding like adhesion, go for those products with proper safety precautions. If you are worried, simply go with a product that is not toxic or harmful to the human body when inhaled.
Durability is another key thing to consider when purchasing metal adhesives. No one likes to see a repaired crack being opened after a few months, if not days. Generally, you get highly durable bonding after properly applying the authentic metal glues. You need to ensure not to compromise the quality of the glue for saving a few bucks.
Benefits of Having the Best Metal Glue
There are countless benefits of using glues for metal. Here are some of them to give you an idea-
1. Highly Adhesive
Glues that are made for metal are highly adhesive and ensures durable bonding. For their high adhesion, you can use metal adhesives for small cracks or breaks in the metals. These ensure almost the same durability as welding.
2. Easy to Use
Metal glues are not much different than other typical glues. So, these are also easy to use for the application. Although some great metal adhesives require you to take precautionary measures to protect yourself from harmful chemical fumes, still it is easy to use compared to other metal repair works.
3. Extends Metal Products Lifespan
Whether you are repairing a tiny crack or attaching two chunks of metal pieces into one, metal glues work great. Apart from repairing, these extend metal product lifespan by quite a decent time. You’ll get an extended working period with your metal tools after repairing with authentic metal glue.
4. Can be used for other tools also
Since metal glues are highly adhesive, you can easily use them for repairing other tools as well. The most popular usage of metal glues includes plastic, wood, glass, jewelry, and ceramic repair.
5. Great for outdoor application
Metal adhesives are waterproof, heat resistant and can withstand significantly low temperatures. So, these are great for applying outdoor where other cheap glues are not great for applying on moisture or heated surfaces.

How to Apply the Best Metal Glue?
Applying the glue to get metal to metal adhesion is a bit different than other gluing techniques. You need proper preparation to get a well-glued surface that does not break. Let’s find out how to do that-
1. Clean both surfaces
The first thing to do is cleaning. You need to remove everything out of the surface, no matter what it is. Generally, you’ll see grease, oil, wax, and dust on the surfaces. Use a brush for the small surface. If you have a big chunk of metal to be glued, use a high-pressure washer for removing any unwanted material from the surface.
2. Ventilate The Work Area
Most of the high bonding metal adhesives work by a chemical reaction that creates harmful fume or irritation to the eyes. So, it is recommended to properly ventilate the room or working outdoors. This will remove the harmful fumes from your surroundings fast.
3. Apply the glue
The third step is the application. When applying metal glue on the surface, make sure to align both the metal pieces for a perfect finish. Since metal glues are highly adhesive and cure almost instantly, you will get a lot less time to adjust than other gluing works, if anything goes wrong. If working on a toy or showpiece that has bends and curves in it, get the help of a person for perfect work.
4. Leave for cure
After the application is done, you now need to leave the metal for curing. Different products have different curing period, so don’t forget to check the product label before application. Some require clamping for a long time and some do not. Follow the exact process that is instructed by the glue manufacturer.
Different Types of Metal Adhesive
There are mainly three types of metal glues you will find in the market. Here are a brief discussion on that-
1. Epoxy Metal Glue
Epoxy is the most popular and one of the best metal adhesives for metal-to-metal bonding. It is a combination of two materials – resin and the hardener. When these two come in contact with each other, they make a strong bonding to the surface. For getting the perfect result, you need to use the perfect ratio of the resin and hardener. After mixing these materials, you’ll get little time to apply on the surface.
This type of glue does not cure clear but ensures waterproof and heat resistant bonding. And a great positive is that epoxy glue is paintable and with a little sanding, you can make things smooth.
2. Polyurethane Metal Glue
Polyurethane is another highly adhesive glue that can efficiently bind metals. This type requires minimum heat to create adhesion, so it can’t be applied in cold temperatures. But comfortable room temperature is good enough to create perfect adhesion.
This type of glue is easy to use and does not require any mixing in the user’s end. You’ll get a pack and only need to apply it. It is flexible and water-resistant allowing you to apply in most of the surfaces. A good advantage of this glue is it is not harmful to the human body and thus good for using in kitchen tools. When it comes to comparison between epoxy and polyurethane, epoxy undoubtedly comes at the top of the table in the high-adhesion category.
Super glues are great for use on any type of surfaces that needs instant binding. For their high-quality adhesion and instant cure, they have been popular with the name ‘Super Glue’ other than the original one “ethyl cyanoacrylate”. These can be applied precisely on any surfaces but you can’t preserve any leftover for future usage in most of the cases. Once they come in contact with air, they start curing.
Does Super Glue Work on Metal?
A lot of people have the wrong perception that super glue does not work well on metal. But it is not the case. Super glues are great for getting strong bonding in metal to metal or metal to glass surfaces. But we do not always recommend superglues for their expensiveness, lack of versatility, and storability.
What is the Strongest Glue for Metal?
As we have already discussed different metal glue types, you should have already guessed it. Epoxy is the strongest glue for metal. This type is the best metal adhesive for metal to glass, metal to wood, metal to plastic, and metal to metal surfaces.
What is the Best Glue to Stick Metal to Metal?
Epoxy glue is the most effective glue to stick metal to metal. You can use these to stick metal to glass, wood, ceramic, and other surfaces as well.
Is Gorilla Glue Good For Metal?
It depends on the model you are talking about. Gorilla Glue is a prominent brand and they offer different types of glue to stick surfaces together. We have reviewed a Gorilla glue model too in this guide. Check that for a detailed answer.
How Do You Fill Holes in Metal?
You can fill tiny metal holes using epoxy filler. As epoxy is the strongest metal adhesive you can find right now, these fill metal holes perfectly. Use a putty knife to get a bit of epoxy glue and apply it on the hole for filling it.
Epoxy Glue vs Super Glue
Epoxy and super glue, both are great adhesives for using on metal surfaces. Epoxy is a combination of two materials – resin and hardener, and super glue is one material that is ethyl cyanoacrylate.
Epoxy glues are great for filling voids, attaching big metal surfaces, and can be easily sanded and painted. On the other hand, super glue is great for smaller surfaces and precise application. Most of the super glues cure transparent where epoxy glues look messy.
When it comes to pressure absorbance, epoxy can take more force than the super glues. Overall, these two materials are great metal glues and have different pros and cons. One should consider his problems and decide the type he needs.
Metal Glue vs Welding
Welding and gluing serve almost the same purpose, attaching two metal surfaces. Where welding needs a lot of tools for binding two surfaces, metal glues can effectively bind surfaces without much ado.
Glue and welding both make the bonding waterproof, heat and weather resistant. Because metal glues are flexible and welding is not, metal glues come on top of the welding.
But for large metal surface binding, welding creates smooth and durable binding with a perfect finish where glues lag.
To sum up, glues are great for using on small repair works whereas welding is mandatory for big metal adhesion works.
Wrapping it Up
Now that you know almost all important things related to metal glues, their benefits, and how to pick one for you, it is advised to apply metal glues in ventilated areas for better safety.
Always go through the product label for manufacturer instructions relating to the application and curing time. You should wait a few more moments than it is advised by the companies for better results.
The best metal epoxy glue should be safe and easy to use, versatile, and strong enough to hold the surface for years.
