Epoxy has the advantage of being water resistant and does a good job of filling gaps in wood. Most other wood glues will not hold well if there is a gap between the pieces of wood being glued together. Epoxy resin is actually the worst choice for gluing most wood projects, although it is the strongest glue. Two-part epoxy glue is known for its high performance, strength and durability.
When applied to wood, it acts as a sealant or filler that hardens to create a durable bond. Its waterproof seal makes it easy to clean and ideal for wooden tables or furniture. After full cure time, it can be sanded or drilled. No other glue is as suitable for wood, making it the perfect adhesive for woodworking projects.
My favorite way to use epoxy glue is to use fast-curing epoxy glue to fill in cracks in projects where the surface is not smooth for some reason. Epoxy glue or wood glue? How to decide? As you can see, it all comes down to the project you're working on. Epoxy is the perfect choice if you have time to cure and are looking to create a strong bond in a weaker wood, but it may be cheaper or easier to use a different glue in other use cases.

If you're talking about gluing wood, it's pretty much a fact that epoxy and PVA glue (such as Titebond) are stronger than wood itself. Epoxy glue is strong enough to hold many types of natural and artificial woods together, even at high temperatures, making it a reliable solution for many home repairs. However, you do have to use water-resistant wood (such as cedar) and be careful that no epoxy gets on your hands or clothes, as it is difficult or impossible to remove without chemicals. Whenever possible, you'll want to hold the wood after you've applied the epoxy so you can achieve the strongest bond.
You can apply epoxy to the wood as long as both sides are clean and dry (don't clean them with water; this just makes it easier for the epoxy to stick). Wood epoxy glues are by their very nature enormously strong, but any bond will be as strong as its weakest link. Wood Epoxy World is dedicated to providing you with the best and most up-to-date information possible on epoxy resin and woodworking. For best results, any liquid epoxy adhesive should be applied to both surfaces to bond them together and allowed to sit long enough for the wood to absorb as much as it wants, so that when the parts are assembled the wood will not absorb the glue that would otherwise fill the space between the parts.
Epoxy works well as a gap filler and as an adhesive when two types of material are joined together (wood is an example). Resin and epoxy share many of the same properties, both harden quickly and are quite strong once cured, but there are some key differences between the two types of glue. There are many different types of glues you can use to glue wood, but the three most commonly used types are PVA glue, polyurethane, and two-part epoxy. That means you're not going to choose epoxy for every joinery project that requires glue, but there is one area where epoxy far outperforms its counterparts.
Epoxy resin has a tensile strength of 7,000 pounds per square inch (psi), while wood glue is generally less than 3,000 psi and screws are between 1,200 and 2,400 psi.
