How to Seal Wood With Epoxy Resin

Epoxy can give wood a waterproof, resilient finish. In most cases, it is an ideal coating for wood projects that will be exposed to moisture or wear. However, there are some cases where it is not advisable to use epoxy as a finish, but you can still get the benefits of epoxy by using it as a sealer before applying your finish coat. While sealing with epoxy will add a bit more time to this stage of your project, the extra effort will pay for itself with greatly increased longevity and lower maintenance costs.

Step 1

Sand the project. The surface should be smooth and free of rough spots, gouges or voids.

Step 2

Remove all dust from the project with tack cloth. Any debris left on the surface of the project at this point will become permanently bonded to the surface when the epoxy is applied.

Step 3

Place newspapers or a drop cloth underneath the project. Epoxy is very difficult to remove from almost any surface.

Step 4

Pour epoxy resin and hardener into a clean coffee can. Stir slowly and thoroughly with a paint stick.

Step 5

Apply epoxy using a bristle brush. Work from the middle of the working surface toward the edges. Always work from wet to dry areas.

Step 6

Check for runs or dry spots as you paint. Porous woods may soak up a considerable amount of epoxy as you work. Aim for a consistent coating.

Step 7

Allow project to cure for 24 hours in a dust-free room.
