can epoxy coating be used on wood?

Epoxy is a great coating for many things, but one question we often get from our customers is: Can epoxy be used to coat wood?

The answer, as you’ll soon discover in this article, is yes! But there are some important considerations that go along with using epoxy on your wooden surfaces.

We’ll cover the basics here so that you can decide for yourself if it’s right for your project.

Can you epoxy coat wood?

It’s possible to use epoxy to coat wood, but you may want to consider some alternatives first.

Epoxy is a two-part liquid that hardens into a solid plastic when mixed together and left to cure for about 24 hours. It is often used as an industrial coating because it is waterproof, durable, and resistant to oil, water, and chemicals.

But epoxy isn’t the best choice if you have lots of time on your hands or if you need something that can be painted over easily in the future (see below).

The chemistry of this substance makes it difficult to work with once applied because it sets quickly and adheres tightly around edges and corners.

How do you epoxy a wooden surface?

  • Sand the surface with fine-grit sandpaper, then clean it with a damp cloth.
  • Apply the epoxy in thin coats and let them dry before applying another layer until you have reached the desired thickness of coating on top of your wood surface.
  • Once you have finished applying all layers of epoxy to your wooden surface, let it cure overnight (24 hours) at room temperature or warmer so that it can harden completely before sanding down any bumps or ridges left from any air bubbles caused by using too much mixture in one area that was not evened out by wiping away excess epoxy before application or during curing after an application has been completed

Should you epoxy wood?

Epoxy is a great choice for wood. It’s a durable coating that can be used to seal or waterproof wood surfaces and make them more resistant to moisture, stains, and damage.

Epoxy also provides excellent protection from UV rays, which makes it ideal for outdoor use.

Because epoxy is so water-resistant, it’s also extremely easy to clean off if you get any on your hands during application (or if you spill some on the floor).

Unlike oil-based finishes or paint, you won’t have to worry about running into those sticky spots when trying to clean up after yourself; just wipe them away with soap and water!

Epoxy is also very easy to repair if anything happens while using your project–you don’t even need any special tools; just a few drops of resin or hardener should do the trick!

What kind of epoxy should I use on wood?

You can use epoxy on wood, and it’s a great choice for a variety of reasons. Epoxy is actually a two-part resin system that you mix together to create an extremely strong coating.

It’s especially good at resisting harsh weather and extreme temperatures, making it a great choice for outdoor projects like decks or patios where you want to avoid chipping or cracking.

Because epoxy dries clear, this is also an excellent finish choice if you want to add some color without having to paint the entire surface first (and then sanding down all those rough edges).

Do you need to sand wood before epoxy?

When you are ready to apply epoxy, you should first clean the wood with a damp cloth and a tack cloth. If the wood has become dusty or dirty from other work, it is important to get rid of that dust before applying epoxy.

You can use a clean cloth to wipe off any remaining dust from your project.

Use fine-grit sandpaper to smooth out any imperfections on your piece of wood before applying epoxy. Sanding blocks are also useful for getting into corners where you need more control over how much pressure is applied to each section of the piece of furniture or another surface you’re working with.

Does clear epoxy darken wood?

You are right, the epoxy is clear.

However, this does not mean that all epoxies will not darken the wood. Some epoxies contain pigment and will naturally darken your surface when applied.

If this is of concern to you, look for an epoxy that does not contain any pigment, or just use a light-colored color of epoxy so that it doesn’t make your wood darker than what you want.

In general, though, most woods used in furniture are stained before applying an epoxy coating on top of them so this shouldn’t be a problem for most people looking to do a project like this at home.

Can you stain wood after epoxy?

No, it’s not recommended to apply any type of stain over a cured epoxy coating. The reason for this is that many stains can bleed into the coating, causing discoloration and damage.

The same would be true if you were staining an old surface that had been previously coated with polyurethane or varnish as well as shellac, lacquer, and other similar coatings.

However, it’s important to note that there are some stains that are formulated specifically for use on cured epoxy surfaces.

These types of stains usually have little to no solvent content and dry very quickly after application so they won’t affect your existing finish in any way whatsoever!

Should I use epoxy or polyurethane?

There are a few factors to consider when deciding between epoxy and polyurethane. First, if you’re looking for the most durable finish, epoxy is the way to go.

Epoxies are more flexible than polyurethanes but not as easy to apply. Polyurethanes are easier to use because they’re less viscous and easier to spread around (they also dry faster).

Polyurethane is also more resistant to UV light than epoxy—a benefit if you live in an area with lots of sunlight or have your boat outside a lot of time.

And while both coatings can be applied with brushes or rollers, it’s generally easier to get good results with a roller when using polyurethane because it’s so easy to apply.


In conclusion, it’s safe to say that epoxy coating can be used on wood. It offers a durable finish that will protect your piece for years to come.

If you’re looking for a way to seal your wooden surface, we recommend using epoxy paint or varnish.
