People have used different kinds of adhesives to join materials for a long time. Different glues have different adhesion qualities to join materials. You can use some glues to join different materials to wood, but it is challenging to stick wood to metal. This article will cover everything you need to know about how to glue metal to wood and create a solid permanent bond. If you want to learn the best glue for metal-to-wood application, read this article thoroughly.
Importance of Using the Right Glue for Joining Wood to Metal
Whatever project you are working on, you must choose the right type of glue for your materials. Many types of glue are explicitly used for wood and other light and porous materials. These glues are unsuitable for hard materials because they have less durability, strength, and resistance to the weather while applied on hard surfaces. Wood is more porous than metal, so it has easier gluing adjustability.
On the other hand, metal is a rigid material for which you have to be very careful about the application process, the size of the material it has to be joined, and the clamping time after applying the glue. Choosing suitable glue will help you to get a long-lasting bond with the materials. It would help if you used glue with a polyurethane base. The glue that contains polyurethane is more likely to be strong and flexible enough to keep the materials joined for a long time.

How to Use Different Glues for Joining Metal to Wood
You can use different glues to join metal to wood, but the glue’s effectiveness may vary in density and porosity. You have to choose the best glue for your project and the proper ways to apply the glue. Wood is more porous but less dense than metal. Penetrating the wood surface is not a preferable way for some people. In that case, they can use glue to attach wood to metal. Let’s introduce some of the best adhesives you can use for bonding.
How to Prepare the Surface
Whatever glue you are going to use on your wood surface to join with metal, you must prepare the surface very well. Preparing the surface before applying glue is a simple process. Here are the methods.
- Clean the service so well and make it free of dust and particles.
- Clean the wooden surface of paint, dust, oil, and grease. Let it completely dry after cleaning. Tape off the areas you are going to work on.
- Sand the metal surface with 120-grit sandpaper if it is tarnished or rusted. Sanding ensures the glue sets onto the surface well.
- Clean thoroughly after sanding.
Two-part epoxy glue is a popular adhesive that you can use to join metal to wood. This glue contains resin and hardener that help to make a strong bond. It comes in different colors. So it is easy to match the glue with the workpiece. Squeeze out equal parts from both the tubes of the two-part epoxy onto a disposable material like a plastic or cardboard piece. You have to mix the glue well and apply it to the surface carefully.
Make sure the mixture is so even that the surfaces are perfectly joined. It usually takes 5 to 10 minutes to sit on the surface. Before the glue is completely set, you can adjust the metal or wood for the correct position. You have to wait about 24 hours for the glue to cure completely.
After curing, removing the glue without causing damage to the surfaces may seem difficult. The lack of flexibility is a significant problem when using two-part epoxy or acrylate glue. It expands after absorbing moisture. Therefore, you have to consider the expansion of the wood and metal surfaces while using this glue.
You have to apply a different technique while using gorilla glue. Try to focus on the manufacturer’s instructions to know the application process. Wood is more porous than metal surfaces. You may need to apply gorilla glue to the wood surface before applying it to the metal surface. However, you may need to reconsider the process depending on the size and condition of the materials.
How is the size of the material an essential factor in determining which material should be glued on first? To clear it out, we can give you a simple example. Suppose you have a smaller metal object to join with a larger wooden surface. In that case, you can get a better result if you apply the gorilla glue to the metal and adjust on wood later on.
On the contrary, you will need to apply the glue to the smaller wooden structure if it has to be joined to a larger metal. You must press and hold the materials together for a particular time in both situations. Pressing or clamping the materials for a pre-set amount of time helps the adhesive to dry and cure very well. It also helps to strengthen the bond.
Superglue is one of the most common and inexpensive adhesives used on multiple projects. This glue offers a high bonding strength and works differently from other glue types. People mostly use this adhesive due to its high resistance to weather, water, and other impacts. Clamping is not mandatory while using this glue. If your wood and metal surfaces are large, superglue might not work well to keep the bond for a long time. However, you can press the materials or hold them together for the recommended time to join them quickly.
Another popular glue to create a strong bond between metal and wood surfaces is E6000 glue. You can use this glue on materials like fiberglass, concrete, ceramics, glass, etc. It becomes waterproof once it gets dried. You can also paint on the glue after drying.
Many of you are probably unaware that liquid nails work well to stick wood and metal materials together. This adhesive is suitable for little repairs on different projects. Liquid nails work pretty well to stick aluminum and wood, but you can also use them on other metal or concrete surfaces.
How can I remove excess glue from a surface?
You can use an acetone nail polish remover to remove the excess glue from the surface. Make sure you do the removal task before the adhesive becomes hard. If the bond is fully cured, you must get it off by scraping, sanding, or cutting it away.
Can I use superglue on all materials?
Superglue is a famous and inexpensive adhesive option for different projects, but it doesn’t work on polyethylene, plastic, or polypropylene. Applying super glue to these materials will dissolve the material with the chemicals in it.
When does superglue bond to a surface?
If your service is not completely dry and clean, you can use a small amount of acetone to remove oil, grease, paint, or dirt. Some wood contains tannic acid that doesn’t let the curing process complete. So it is good to remove. The oily substance is from the surface with some activator.
Which glue should I use to join metal to wood?
You can use different types of adhesives to join metal and wood, but superglue is the best option if you are a DIY or craft enthusiast. If you work professionally and want a perfect adhesive for larger projects, you should choose epoxy.
Many of you are confused about whether it is possible to join metal to wood because they have different densities and porosity. Depending on the project you are working on, the size, and the condition of your project materials, you must first determine whether you should apply glue on the wooden surface or the metal.
You should also be aware of the specific instructions and application procedures for the glue type you want to use. Hopefully, this article has fulfilled your requirements on how to glue metal to wood using the most effective and potent adhesives.
