Step 1 of 4: Safety Precautions 

The first step is to ensure your safety. Particleboard is manufactured from particles of wood glued together. When you cut the board it will shoot flakes, wafers, and strands. Wear safety goggles and a face mask to protect yourself from these splinters. 

Taking these precautions will save you from any occurrence. After you’re done wearing safety goggles, masks, and hand gloves only then proceed to the next step. 

Step 2 of 4: Measuring and Cutting

Take the measuring tape and measure out the necessary pieces of the particle. Use the marker to mark where to use the saw. You can also use masking tape on the board to have the perfect cut. Make sure to remove the masking tape after taking measurements. 

Wear your goggles to protect yourself from sawdust. Now, take the saw and start cutting the wood. You need to cut through the wood gradually. 

You can use a circular saw or a jigsaw to cut the board. Be careful to not hurt yourself during this step.

Step 3 of 4: Applying the Sealant 

You need clear acrylic sealant for this step. You will notice some open edges on the board. Take a coat of sealant. Now, start applying the coat of clear acrylic sealant.

You can start with the thinner parts and then go to the larger ones. You can choose to apply it with a paintbrush or your fingertips. 

Try not to use any kind of glue on the particleboard. Use glue if you want to attach plastic to wood

Do not keep any part of the edges dry.

Step 4 of 4: Drying the Sealant 

Now take the knife and scratch off the extra sealant. We need an ample amount of air to make the sealant dry quickly. If you maintain a normal room temperature and ventilation system it will be enough for drying.

Don’t try to rush this part. Just take time and ensure the sealant is dry before moving on. If you see any bubbling after the sealant dries it means you haven’t put the sealant properly. Dry the particleboard just like you dry a wet wood floor
