Can you mix epoxy and wood glue? It’s one of those questions that actually makes a lot of sense. After all, many people like the idea of combining the best features of both products.
But it’s also a question that can be very confusing if you don’t really know what you are looking for. In this article, we want to help you understand the differences between wood glue and epoxy so that you can make smart decisions about which ones to use in certain situations.
Does epoxy interact with wood glue?
Some people think that epoxy and wood glue is the same thing, but they’re actually very different. Both are polymer-based adhesives, but most epoxies are thermosets and wood glue is a thermoplastic.
Thermoplastics can be reheated and remolded, while thermosets cannot, which means their chemical compositions differ as well.
Things like the hardness of the final product, how long it takes to cure, what temperature(s) it can withstand upon cure, and whether or not it’s waterproof/water resistant—all these can vary drastically between wood glue and epoxy.

Can you mix glue and epoxy?
Take a moment to read the labels on the glue and epoxy you’re using. If you don’t know: The glue won’t tell you what epoxy to use, but it may instruct you on how to prepare your surfaces before applying the product.
The instructions for your specific brand of epoxy should also be included in the box or at least available for download directly from the manufacturer’s website. Those instructions will most likely include information about which glues are safe to use with their product. Use that information!
In general, there are two types of reactions between wood glues and epoxies: Some will cause wood glue to break down over time, while others will remain inert when they come into contact with each other.
Which is stronger epoxy or wood glue?
Epoxy is stronger than wood glue, generally. This fact is based on the industry standard of shear strength, which measures how well materials can withstand forces that push them to slide past one another.
Once epoxy has cured and hardened, it is incredibly strong and resistant to most chemicals that would cause it to break down or separate.
While epoxy adhesive will indeed bond a variety of substrates (the surfaces being bonded) together in a strong way, there are some factors that must be considered.
What happens if you mix super glue and epoxy?
When it comes to gluing things together, there are a few options. Some of the most popular are super glue, epoxy, and wood glue. You’re likely familiar with all three. But have you ever wondered if you could just combine them? Well, we have some bad news for you: this is a terrible idea.
If you try to mix epoxy and super glue (or any other kind of chemical adhesive), they will react negatively—and bond to each other! Ugh! Terrible! The end result is that nothing gets glued together because your adhesives are now stuck to each other. And on top of it all, this reaction will create new toxic fumes! Run from the room immediately!
Will epoxy resin hold wood together?
Epoxy resin is not a type of wood glue, but it can sometimes be used to bond wood. Epoxy resin cures to a solid plastic material which will provide a strong adhesive bond similar to superglue in strength.
How well does epoxy bond to wood?
Epoxy has several advantages over wood glue when it comes to bonding. The main difference is that epoxy creates a stronger, more permanent bond with the wood because of how it polymerizes and hardens.
Also, epoxy is more waterproof than wood glue, meaning it won’t wash out in water as wood glue will. However, epoxy is also pricier and harder to sand and paint over than wood glue.
Will epoxy bond to epoxy?
If you try to combine epoxy with another type of glue, like wood glue or super glue, it won’t work. Glue is made up of ingredients called polymers. These are long molecular chains that can make a sturdy net when they are mixed together. Epoxy and polyethylene both have these polymer chains, but they have very different chemical structures.
Epoxy is a thermosetting polymer, while polyethylene is thermoplastic. Epoxy cures (hardens) by reacting with other chemicals in the air or in another liquid. Once this process is complete, it will stay solid even if it’s heated up again or gets wet; that’s why it’s often used for coatings on metals like car parts and aircraft wings!
On the other hand, polyethylene melts when heated and then hardens again once cooled down. That’s why water bottles made from this material can be recycled into other things such as plastic bags without losing their strength.
Because epoxies don’t melt easily (like most plastics do), they are great materials to use as adhesives for items that need to stand up against water exposure or high temperatures—including those made from plastic! If you ever want more information about how these types of glues work together so well together then contact an expert at the local hardware store.”
Does Gorilla glue epoxy work on wood?
Because of its strength, Gorilla Epoxy is great for outdoor applications where it will be exposed to the elements. It takes 24 hours to cure and holds strong with a tensile strength of 4,200 PSI. Once cured, this glue is resistant to water, most chemicals, and freezing temperatures.
It has a long shelf life (2 years in its unopened tube), but after opening it should be used within 30 minutes.
If you want to make sure the epoxy doesn’t discolor your project—perhaps you’re using light-colored wood—you can use another product in the Gorilla Glue family: Wood Glue Max. Wood Glue Max is waterproof and also bonds well on acrylics, PVC, plastic, and glass.
Conclusion
So, can you mix epoxy and wood glue? The answer is yes! However, epoxy is better for wood to metal bonding and wood glue is better for wood to wood bonding.
