Epoxy is a resin that can be used to glue, seal, or coat objects. It’s a popular choice for woodworking projects because it’s durable and waterproof.
However, many people wonder if epoxy can be applied directly to wooden surfaces. In this article, we’ll explain how to use epoxy on wood and answer questions such as: Can you put epoxy on wood? What kind of epoxy should I use? Will the wood absorb the epoxy? Is there an advantage in using marine-grade resin over regular resin?

Can you apply epoxy directly to wood?
You can apply epoxy directly to wood. Epoxy does not absorb into wood and it’s a great choice for finishing and repairing wood surfaces, as well as protecting them from moisture.
What kind of epoxy should I use on wood?
Epoxy resin is a two-part resin, meaning it’s made of two different parts that must be mixed together before you can use it.
Epoxy resin is a hard, clear plastic that can be used to repair wood or metal surfaces. Epoxy will adhere well to both wood and metal but may not work well on plastics.
If the area you’re trying to repair is in direct contact with water (like a boat hull), then epoxy might not be the best choice for you because it will eventually begin absorbing water from its surroundings over time.
How do you stick epoxy to wood?
When it comes to sticking epoxy to wood, there are a few options.
- If you have time and money to burn, you can try using a primer and bonding agent. The primer will help prepare the surface of your wood for adhesion and the bonding agent will make sure that everything stays put.
- Use solvent alone if you’re feeling bold or have lots of time to waste; this method works well on any type of porous material (including metal) but requires more effort than other solutions because when mixed with epoxy gels they tend not get as hard as some other sealants would when curing–so be careful!
Should you epoxy wood?
Epoxy is a two-part resin that is used to coat and protect various materials. It can be used to coat wood, metal, concrete, fiberglass, and more.
Epoxy is also waterproof and heat resistant up to 350 degrees F (176 Celsius).
Do you need to sand wood before epoxy?
We’re all for saving time, but not if it means sacrificing quality. Sanding is optional when applying epoxy to wood because many people like to do it and most people don’t even realize it can be skipped.
You can apply epoxy right over raw wood without sanding first. However, there are two things to consider before skipping this step:
- If you don’t sand first and then apply the epoxy, what will happen? The surface of your project will be bumpy due to uneven layers of stain (and some may get worse depending on how thick or old your existing finish is). This isn’t necessarily bad; however, if you want an extra smooth finish top coat over top of this rough texture after curing your epoxy then we would recommend sanding prior to applying any topcoat products such as a glossy sealer or varnish
What is the strongest epoxy for wood?
There are several different types of epoxy available for wood. Epoxy resin, polyurethane, polyester, polyamide, and polyvinyl ester are all strong adhesives that can be used on wood.
Epoxy resin is the strongest adhesive but it is also the most expensive and requires heat to cure properly. Polyurethane adhesives are less expensive than epoxy resins but they do not have as long shelf life or as high ultimate bond strength when compared with epoxies.
The other three types of adhesives are lower-cost alternatives to epoxies with similar performance characteristics except for their ability to withstand moisture exposure over time (polyester is somewhat resistant).
Polyurethane bonds well in both wet and dry conditions; however it does not adhere well when exposed to water before curing (ease of immersion).
Epoxies cure quickly at room temperature but require heating before application in order for them to attain full strength after curing (i.e., “bake” them).
How long does it take epoxy to dry on wood?
Epoxy resin is a two-part system, meaning it comes in two separate bottles. When you mix the resin and hardeners together, they form a chemical bond that hardens into a solid substance.
How long epoxy takes to set depends on how much water was used when mixing it. The more water added to your mixture, the longer it will take for your epoxy to set (because there is more moisture).
In general, if you use equal amounts of resin and hardener with no extra water added then your project should be dry within 24 hours. If you add too much water or if it’s warm outside then this drying time can increase significantly.
Does epoxy resin soak into wood?
Epoxy resin does not soak into wood, but it bonds to the wood. Epoxy is a chemical that reacts with both the wood and the other ingredients in the epoxy resin.
The result of this reaction is a strong bond between those two materials and therefore makes them resistant to water damage, which can break down some other types of furniture finishes.
The answer to this question is yes. Epoxy can be applied to wood and it will bond with the wood fibers. The most common epoxies used in construction are two-part systems that require mixing before application.
These epoxies cure under heat and pressure so they must be applied thick enough to ensure adhesion at all locations where there is contact between the two surfaces being bonded together (no gaps).
Another type of epoxy that can be used for bonding wood is one-part, but these products do not provide adequate strength for structural applications as they tend to shrink away from gaps after curing (due to lack of crosslinker)
