How to Protect Particle Board

Quck answer

Particle board is a commonly used material in furniture and construction. It is made from wood particles bonded together with a resin adhesive. However, particle board is susceptible to moisture damage, which can cause it to swell and deteriorate. To protect particle board from moisture, it is important to seal it properly. Here are the steps to seal particle board:

1. Clean the surface: Remove any dirt, dust, or debris from the particle board surface using a soft cloth or brush.

2. Sand the surface: Lightly sand the particle board surface with fine-grit sandpaper. This will create a smooth and even surface for sealing.

3. Apply primer: Use a paintbrush or roller to apply a coat of primer to the particle board. The primer will help the sealant adhere to the surface.

4. Seal the edges: Pay special attention to the edges of the particle board, as they are more susceptible to moisture damage. Apply an extra layer of primer and sealant to the edges.

5. Apply sealant: Use a paintbrush or roller to apply a coat of sealant to the entire particle board surface. Make sure to cover the surface evenly and allow the sealant to dry completely.

6. Sand and repeat: After the sealant has dried, lightly sand the surface again with fine-grit sandpaper. Apply another coat of sealant and repeat this process for added protection.

By following these steps, you can effectively seal particle board and protect it from moisture damage. Remember to always read and follow the instructions provided by the sealant manufacturer for best results.


Particle board is a manufactured wood product that is commonly used in construction projects. It is important to prevent moisture from reaching the particle board in order to maintain its strength and integrity. In addition to proper storage, applying a waterproof sealant before installation will ensure long-lasting results.

Step 1

Measure and cut the particle board pieces needed for your project using a circular saw. It is important to wear safety glasses to protect your eyes from potential splinters.

Step 2

Apply a coat of clear acrylic sealant to all edges of the boards, as well as any areas that may be exposed to moisture. Shake the sealant can, open the lid with a screwdriver, and use a paintbrush to apply the sealant. Paint rollers are not as effective in penetrating the wood.

Step 3

Allow the sealant to dry completely for several hours before installing the particle board.
