There are many types of glue to choose from, but not all of them provide a permanent bond when sticking metal and wood together. This is because some adhesives only stick well on one material or the other – so you’re left with no reasonable option if your project involves both.
In this article, we will discuss the best ways to select glue for metalworking projects and how it can provide you with an incredible bond between different materials while also being user-friendly.

Things to Consider When Buying Glue for Metal to Wood
The best glue for sticking metal and wood together is not a straightforward answer. There are some factors to consider to ensure that you get the correct adhesive for the job.
Here are some of the things to consider when choosing glue for projects involving metal surfaces:
1. Type of Glue
There are different types of glues that can be used to bond metal to wood, each with its strengths and weaknesses. These include epoxies, cyanoacrylate-based adhesives, and polyurethane-based glues.
Epoxy is arguably the best type of glue for metal to wood, but you should use a two-part solvent-free epoxy for projects involving bonding metal to wood. Two-part epoxy is strong, waterproof, and resistant to heat, chemicals, humidity, and other elements.
The downside of epoxies is that they cure very slowly and can take more than one day to dry fully, which can be inconvenient when working on large projects.
Polyurethane-based glues are another remarkable option when sticking metal to wood. They are moisture-resistant and cure quickly while providing high adhesion. However, because they are highly flammable, you need to be cautious when working near open fires.
Commonly known as superglues, cyanoacrylate-based adhesives are another great option. They are helpful in gluing just about anything, but some options are designed to deliver excellent results for metal-to-wood bonding.
The best thing about cyanoacrylate-based adhesives is that they are easy to use and deliver instant results. As for weaknesses, superglues create somewhat weaker bonds and may have an unpleasant smell for some people.
The best type for you will depend on the project you have in hand. Generally, epoxies deliver remarkable results and are ideal for large projects because they have low open time.
2. Materials You are Bonding
When buying glue for bonding metal to wood, you also want to make sure it is suited for the metals you want to stick to wood. Typically, manufacturers indicate what kinds of metals the glue works for.
Even so, it is safe to say that epoxy and polyurethane-based glues work best for most projects. They will deliver excellent results when bonding aluminum, metal sheeting, and metal sheeting to wood.
Of significance, using polyurethane-based adhesives is discouraged when working with copper as the fumes from the adhesive can result in reaction and corrosion.
Cyanoacrylate-based glues deliver immediate results but create a weak bond.
3. Application Type
Most glues are designed with dispensers, allowing for easy application and minimizing the chances of making a mess. All in all, you should not assume the type of application because not all glues come with dispensers.
There is spray glue which poses a higher risk of making a mess. For this reason, spray glue for metal to wood is recommended for professionals. Some two-part epoxy options need to be mixed manually before application and may not be ideal for DIYers with little experience.
When it comes to making a decision, choose a glue that you can apply without hassles. It is common knowledge that glues with dispensers are easier to use.
4. Resistance to Elements
Before making any purchase, you definitely want to check if the glue in question is resistant to elements. Of course, the level of resistance you need will depend on the project at hand.
The best glue for metal to wood should be waterproof and resistant to heat and other chemicals. In some cases, you may need glue that can withstand high pressure.
5. Bond Strength
Measured in pounds of force per square inch (PSI), the strength that a particular type of glue can create is a crucial factor to consider before making a purchase. This is extremely important when bonding large and heavy products.
To ensure you are buying the suitable glue for your project, it is always a good idea to check out the PSI the glue can handle when it cures.
Generally, the heavier and larger the metal and wood to be glued, the higher the tensile strength needs to be. An ideal option should seal and fill all gaps very well to minimize lines of weakness as well as dry relatively flexible to withstand cracking and potential damage that can occur due to movement.
6. Clamping, Setting, and Curing
Most glues require clamping to create a reliable bond. Other options, especially thick adhesives, do not necessarily require clamping. For this reason, if you are buying glue that requires you to use clamps, make sure you have or can access them.
Also, pick a glue metal to wood glue with a reasonable setting and curing time. The glue that dries faster will allow you to get to work within a short while. However, this doesn’t mean you should use glue that delivers inferior results because you want to get to work as soon as possible.
