Wood Glue
Wood glue is a powerful adhesive specifically tailored to fuse wood together. By penetrating the fibers of the wood, it produces a robust, permanent bond capable of withstanding intense force. This indispensable tool can be used for an array of carpentry projects; from revitalizing furniture to crafting new pieces from scratch.
Different Types of Wood Glues
Today, woodworkers enjoy a broad selection of wood glues, ranging from polyvinyl acetate (PVA) to polyurethane-based adhesives.
PVA wood glue is water-based and dries clear, making it ideal for projects where appearance is important. It is effortless to remove with water prior to it drying.
In contrast, Polyurethane glue forges an immensely durable connection between pieces of wood, yet it can be intricate to work with as it swells upon drying and demands special care during application.
There is also hide glue. This is a type of adhesive that is made by boiling the connective tissues and bones of animals, such as cows or horses. The resulting liquid is then processed to create a strong, durable adhesive that has been used for centuries in woodworking, musical instrument making, and bookbinding.
However, hide glue does have some drawbacks. It can be difficult to work with, as it requires careful temperature control and preparation. It also has a relatively short shelf life once it has been mixed, and can spoil if not stored properly. Due to these causes, modern woodworking typically disregards this choice.
Advantages and Disadvantages
The cost-effectiveness of wood glue makes it an attractive option compared to other adhesive alternatives. It’s also easy to find at any hardware or home improvement store.
Additionally, wood glue creates a bond that can last for decades if applied correctly. Also, It will dry faster than Epoxy resin. For more information on wood glue drying time, go to my article How Long Does Wood Glue Take to Dry? 5 Tips You Should Know!
Despite the benefits, there are some hindrances associated with using wood glue. For instance, it takes longer to set than other bonding agents such as cyanoacrylate (i.e., “super glue”).
Additionally, certain types like PVA may not hold up as well in high-stress situations compared to polyurethane versions. When considering using wood glue for your project think about the type you need based on its properties: strength required and visual appearance after drying (transparency or color).
You can dive deeper into the knowledge of wood glue in my article Understanding wood glue + 8 awesome tricks you should know.
Epoxy Glue
Epoxy, like wood glue, is an adhesive used in woodworking. Nevertheless, epoxy is comprised of two components: a resin and a hardener. When blended, their chemical reaction creates a strong connection able to endure high levels of pressure and strain.
The bond created by epoxy glue for wood is often stronger than the wood itself, making it a popular choice for high-stress applications such as boat building and aircraft construction. Epoxy permeates and bonds with the wood’s fibers, forming a strong chemical connection between it and the wood.
This creates a bond that can be difficult to break, even under high stress. Additionally, epoxy has excellent gap-filling properties, meaning it can fill in small gaps or cracks in the wood to create an even stronger bond.
Two-Part vs One-Part Epoxy
Two kinds of epoxy exist: two-part and one-part. To utilize two-part epoxy, the resin and hardener must be mixed together just before application.
It then typically has a limited working time before it starts to harden. After curing fully (which can take up to 24 hours), two-part epoxy creates an extremely strong bond.
One-part epoxy is pre-mixed and ready to use out of the container. Boasting a simplified application process, one-part epoxy is generally more effortless to use in comparison to two-part epoxy which necessitates mixing and measuring.
Advantages and Disadvantages of Using Epoxy Glue
Epoxy is renowned for its superior strength; forming powerful connections that are difficult to fracture, even under extreme strain. Additionally, due to its remarkable gap-filling properties, it is an ideal choice for sealing small cracks in wood and strengthening the bond.
However, epoxy also comes with some downsides. For example, it can be more difficult to work with than wood glue because of its limited working time and the need for specific ratios when mixing two-part epoxy.
Next to that, Epoxy wood glue has a longer curing time. You can read all about that in my article How Long Does Epoxy Glue Need to Dry: a Comprehensive Guide.
Additionally, two-part epoxy requires special handling and disposal procedures to ensure that it’s used safely and responsibly. Epoxy tends to be more expensive than wood glue, though the increased strength and durability may make it worth the added expense for certain projects.
Comparing Wood Glue vs Epoxy
Are you seeking a dependable adhesive for your carpentry works? You may have encountered both wood glue and epoxy but are unaware which one is the most suitable for your endeavour. To help you make an informed decision, let us assess how they contrast in terms of strength, flexibility, and other key factors.
Epoxy vs Wood glue Strength
Epoxy is often regarded to be more robust than wood glue when it comes to strength. This is because epoxy forms a chemical bond with the materials it is adhering together, whereas wood glue relies on physical adhesion.
Epoxy can also fill gaps and cracks better than most types of wood glue, making it an ideal choice for projects where maximum strength is required. Nevertheless, wood glue is powerful enough for the majority of carpentry undertakings.
In fact, many types of wood glue have impressive tensile and shear strengths that make them perfectly suitable for most joints. When choosing between the two adhesives based on strength alone, consider the specific requirements of your project and choose accordingly.
Wood glue vs Epoxy: Flexibility
Flexibility is another factor to consider when deciding between wood glue and epoxy. Wood glue tends to be more flexible than epoxy once cured, making it a good choice for joints that need to withstand some movement or vibration without breaking apart.
For example, if you’re building a chair with legs that will experience some flexing as people sit down and stand up from it repeatedly over time.
Epoxy tends to be more rigid once cured than most types of wood glue. This makes it a better choice for joints that need to stay stiff and rigid over time without any movement or shifting whatsoever.
Shelf life
When considering long-term reliability and permanence, there are some essential differences between wood glue and epoxy wood glue that warrant attention.
Wood adhesive, otherwise referred to as PVA glue, typically has a shelf-life of one to two years; nevertheless, this could differ based on the exact brand and kind of wood glue. For optimal longevity, it is essential to keep wood glue in a cool, dry environment, clear of direct sunlight and heat sources. Learn how to store in my article How to Store Wood Glue for Optimal Performance? 3 Quick Tips
Epoxy glue can outlast wood glue with a shelf life of up to two to three years, so long as it is stowed appropriately. One must be mindful of heat and exposure to sunlight when storing epoxy glue, so it is advisable to maintain cool, dry conditions. My article, “How to Store Epoxy Glue: Best Practices to Ensure Longevity” outlines all the tips you need for preserving epoxy wood glue in optimal circumstances.
Sure, here is an updated comparison table that includes advantages of each adhesive:

When to use wood glue vs epoxy glue
Which adhesive should you select for your carpentry project? Is wood glue stronger than epoxy? This inquiry is contingent upon various aspects, including the kind of joints you are bonding, the variety of wood in use, and how the final product will endure over extended periods.
If you need maximum strength when bonding different types of material and can tolerate some rigidity in your joints, epoxy is a good choice. It’s also ideal for projects where filling gaps or cracks is necessary.
On the other hand, if flexibility is more important than sheer strength and rigidity, and for gluing wood to wood, then wood glue may be a better choice. Wood glue is also easier to clean up than epoxy and can be sanded/cut easily once dry.
Ultimately, choosing between wood glue and epoxy will depend on your specific project requirements. For example, epoxy glue is not that food safe as you might think, go to this article to see more. Ensure that each factor is taken into account before you make your choice, so that the outcome is stunning and lasts for a lifetime!
Tips for Using Wood Glue and Epoxy
Preparing Surfaces Before Applying Adhesive: A Crucial Step
Before applying any adhesive, it’s important to properly prepare the surfaces that will be bonded. For wood glue, this means making sure the surfaces are clean and free from dust or debris. It’s also a good idea to lightly sand the surfaces to ensure a tight bond.
For epoxy to adhere properly, degrease the surface with acetone or another cleaning agent and gently sand them to provide a stable foundation. Doing so maximizes adherence, ensuring that the epoxy won’t loosen over time.
Applying Wood Glue: Get Clamping Right
For a successful result when using wood glue, sufficient force must be applied during clamping. You want to ensure that there is enough glue applied between the two surfaces so that they adhere tightly together when pressed firmly under clamps.
However, you don’t want too much glue as this can cause excess squeeze-out which can be difficult to clean up after curing. Also make sure that you use enough clamps – one clamp every six inches is usually sufficient. Learn how to use wood glue in my article How to Use Wood Glue? a Clear Step-By-Step Guide
Curing Epoxy: Know The Timing
When working with epoxy, it’s important to keep in mind its cure time and temperature range for best results. Curing time of an epoxy joint is dependent on temperature and humidity conditions of your workspace; higher temperatures lead faster cure times while cooler temperatures lead longer cure times.
Once you apply the epoxy onto both surfaces applying pressure via clamping ensures maximum adhesion and prevents air pockets from forming between parts being joined after mixing two components together.
Overall both wood glue and epoxy are effective adhesives when used properly, but it all comes down how well they are applied and prepared for optimal results – so make sure you take your time and follow these tips for the best outcomes.

Wood glue vs Epoxy – Conclusion
To summarize, the decision between wood glue and epoxy glue relies on the project at hand. Acknowledge their individual assets and shortcomings when considering their relative capabilities. If a wood-to-wood joint is what you are working on, then wood glue is your top choice; epoxy wood glue would be better for connections involving metal or glass parts.
In cases where strength, durability, and water resistance are needed, epoxy glue should be your go-to. However, if intricate details and extended working time are the priority, then wood glue fits the bill.

How do you make wood glue last longer? ›To preserve their workability and strength, store your glues in a tightly sealed container, out of direct sunlight, and at room temperature. For example, if allowed to freeze and thaw repeatedly, yellow and white PVA glues thicken to a pudding-like consistency and become difficult, if not impossible, to spread.
Can you use too much wood glue? ›Use the Right Amount of Glue
Too much glue makes a mess and wastes glue. With practice, you'll know just how much to apply. You should see a continuous line of small glue beads. When this perfect glue joint sets a little, you'll find it easy to scrape off the jelled excess, and you'll have very little cleanup to do.
Also, wood glues tend to be around 50% solids and therefore shrink when they dry. If the rough surface is too “gappy,” as the adhesive dries and shrinks, it will pull away from one surface or the other leaving gaps in the glue line, which again will concentrate force when the joint is stressed.
Is epoxy stronger than wood glue on wood? ›Well, epoxies are generally stronger than wood glues, and therefore more durable and longer lasting. But wood glues are more affordable, they're easy to apply, and there are different kinds for different purposes. In the end, you can't go wrong with either wood glue or epoxy when working on your woodworking project.
Do I need to seal wood before epoxy? ›
