How do you seal wood before epoxy?

You may know nothing about epoxy and its use on wood, but you probably know that wood is a porous material. It absorbs moisture from the air as well as certain other liquids. When it comes to using epoxy with wood projects, you don’t want the wood to absorb your resin.

Why? Because it can make for a very ugly final product! Your project will look warped, bubbled, and uneven. Plus, if your resin is absorbed into the wood, then you’re basically wasting epoxy. You could have used less resin!

The answer is simple: seal your wood before using epoxy on it. This step is both simple and budget-friendly (you can find some sealants at the dollar store!), so there isn’t any excuse to skip out on such an important step in the process!

Should you seal wood before epoxy?

You can use epoxy resin with any type of wood, but you need to seal it properly beforehand.

Sealing the wood before applying the epoxy will prevent warping and give your piece a smooth, glossy finish.

The most important thing when sealing the wood is to ensure that no air bubbles are trapped in the surface. If there are air bubbles trapped in the sealant, they will also be trapped inside your resin once you pour it over.

This is why many people opt for sanding their wood before sealing it — sanding helps to remove any raised grain that could trap air underneath your sealant.

However, if you prefer to keep your table as natural as possible, or you don’t want to change its color by staining it first, then sanding isn’t necessary.

How do you seal wood before epoxy resin?

You’re going to need to clean the wood you’re working with first. You can do this with a damp rag and then let it dry completely.

Next, use sandpaper to sand the surface, making it nice and smooth so you don’t have any rough spots. If there are any holes in the wood that you want to be filled, fill those using epoxy.

Then apply 2 coats of epoxy – one thin coat and another a bit thicker – to seal the wood before applying your final layer of resin. Remember that each coat will take 4-6 hours to cure before you can apply another one or move on with your project.

How do you prepare wood for epoxy?

To prepare wood for epoxy, you have to remove old finishes from the wood, sand it down, and clean it to get rid of any dust or dirt.

Prepare your epoxy by mixing it together with a ratio of 1:1 for best results. Apply the epoxy in thin layers over the entire surface of the wood, scraping off any excess as you go. After about 10 minutes, wipe away any drips that have formed on the edges of your work area.

How do you seal the live edge before epoxy?

Sealing the live edge for epoxy requires only a few items and takes very little time.

The best way to go about sealing your live edge is to use this method:

  • Apply one coat of sealer with a brush
  • Use either a plastic lid or a piece of cardboard as your mixing surface
  • Take your cheap 2-inch brush and put some wood sealer on it
  • Apply the wood sealer in long, even strokes while making sure not to miss any areas
  • If you’re working on vertical surfaces, work from top to bottom

Do you stain wood before epoxy?

Yes. Stain is a great way to bring out the depth and grain of your wood, and it can create some really cool

effects—however, if you’re using a clear epoxy or just want a natural look, you may not need to stain.

In terms of colorants, there are two common options: wood dye or wood stain. Wood dye is purely for color and won’t affect the consistency of the surface.

You can generally get pure white but most other colors will come out transparent or translucent (unless you use a heavy concentration).

Wood stains work like paint, with pigment that sits on top of the surface to give it an opaque finish (use this if you want solid colors).

How do you keep epoxy from bleeding on wood?

Laying epoxy on wood is no easy task, particularly if the wood you’re using is porous or has a lot of grain. Before applying resin to the wood, it’s also important to thoroughly sand off any dust or debris on the surface.

(More than likely this will be done by your handy DIYer-type friend… and I mean that in a good way! When he/she’s not helping out at family gatherings.) Next step? Apply resin. This will help seal the wood in place and make your finished project look nicer and more professional.

When you’ve got the resin applied, it’s time to apply epoxy. The key here is that you don’t want to get any epoxy on your skin—it’ll sting! If this happens accidentally, pat yourself down as soon as possible with paper towels until no red spots can be seen.

Once your piece of furniture is covered in epoxy resin and has been left for 24 hours (if it was wet when you applied it), sand off all the excess—this will give a nice even finish when you apply a second coat of epoxy. It’s imperative that you allow this second application of epoxy to cure before sanding again!

How do you seal wood resin?

You can use a spray sealer, with an aerosol can or spray bottle. You want to make sure the sealer you are using is water based, because other sealers will not work when you apply the epoxy over top.

The most important thing to remember when dealing with porous wood and epoxy resin is that you need to ensure the wood is dry before applying the epoxy.

Once the wood has dried completely, then you can apply a coat of your sealer product on top of it. Allow this coat of sealant to dry as well, before applying your epoxy resin mixture.

If you do not wish to apply an additional layer of product on top of your wood prior to sealing it with epoxy resin, there are several products available that will provide excellent adhesion between your wood and resin.

If your project involves multiple layers and compartments for different types of items (such as jewelry), I always recommend that you use these types of products between each layer.

They allow for better adhesion between compartments as well as allowing for an easier cleanup once your project has cured.”

What do you use to seal epoxy resin?

When you’re sealing your wood projects, you have several different choices of what to use. You can go the varnish route, which usually requires the use of a brush or sprayer. This method uses lots of elbow grease and some fine-tuning to get a nice finish on your work.

Another common choice is polyurethane varnish. It’s often more affordable than lacquer (which is more expensive than shellac), but it still offers the same level of protection on wood surfaces as the other two options—and it also gives off a nice finish that goes well with epoxy resin.

The only downside? Polyurethane varnish dries slowly, so you have to wait for it to dry before moving on to another project.


Now that you know how to seal your project before using epoxy resin, you can start experimenting with your resin. If you are hoping to make your project look more beautiful, the sealer is a great way to do it. You can also use sandpaper in order to make the project look more beautiful.

The sandpaper will help smooth out any bumps on the surface and it will also help seal the wood before the epoxy resin is added. The sandpaper and the sealer are very important parts of an epoxy resin project.
