How to Apply Epoxy Resin to Seal Wood

Quck answer

Epoxy resin is a popular choice for sealing wood due to its durability and protective properties. To seal wood with epoxy resin, follow these steps:

1. Prepare the wood surface by sanding it smooth and removing any dust or debris.

2. Mix the epoxy resin according to the manufacturer’s instructions. Be sure to wear gloves and work in a well-ventilated area.

3. Apply a thin coat of epoxy resin to the wood using a brush or roller. Make sure to cover the entire surface evenly.

4. Allow the resin to cure according to the manufacturer’s recommended curing time. This usually takes 24-48 hours.

5. Sand the cured resin lightly to remove any imperfections or rough spots.

6. Apply a second coat of epoxy resin if desired for added protection and a glossy finish.

7. Allow the resin to cure completely before using or applying any additional finishes.

By following these steps, you can effectively seal wood with epoxy resin, providing long-lasting protection and enhancing its natural beauty.


Epoxy resin can provide wood with a durable and waterproof finish. It is particularly useful for wood projects that will be exposed to moisture or wear. However, there are instances where using epoxy as a final coat is not recommended. In these cases, you can still enjoy the benefits of epoxy by using it as a sealer before applying the final coat. Although sealing with epoxy may require additional time and effort, it is worth it as it significantly increases the lifespan of the wood and reduces maintenance costs.

Step 1

Begin by sanding the wood project to ensure a smooth and even surface, free from any rough spots, gouges, or voids.

Step 2

Thoroughly remove any dust from the wood surface using a tack cloth. Any debris left on the surface will become permanently bonded once the epoxy is applied.

Step 3

Place newspapers or a drop cloth beneath the project to protect the surrounding area. Epoxy is extremely difficult to remove from most surfaces.

Step 4

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

Step 5

Apply the epoxy to the wood using a bristle brush. Start from the center of the surface and work your way towards the edges, ensuring even coverage. Always apply the epoxy from wet areas to dry areas.

Step 6

While painting, check for any runs or dry spots. Porous woods may absorb a significant amount of epoxy, so aim for a consistent coating.

Step 7

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