Step 1: Safety Precautions

Woodchips, sawdust, and glue are used to make particleboards. When cutting or trimming the boards, it’s common for these chips to fly into the air.

First, use a marker to mark the areas where the particleboard will be put. Then, using a measuring tape, measure the size of the area. Take width and height measurements and write them down in a notepad.

Mark the same measurements on the particleboards. Make sure you’re using the correct measurements for each area. Don’t confuse the board’s width with its height.

If one measurement of the board is wrong, the whole structure would be ruined. Just like one bad outlet can cause all others to stop working.

Step 3: Cut the Board

Now that the boards are properly measured, time to cut them. Put on your safety goggles and cut the board using a jigsaw or a circular saw.

Don’t try to go too fast while cutting the board. Take your time and cut along the line you have just drawn. This will ensure a safe and proper cutting of the boards.

Before applying the sealant, give it a good shake to thoroughly mix the ingredients. Apply an even layer of sealant around the boards with a small amount of sealant. You can do this with a small painting brush.

Apply an additional coat of sealant to areas that are more likely to be exposed to moisture. Make sure the sealant is evenly applied on both sides of the board. Use the large painting brush while applying the sealant on the surface of the board.

Step 5: Let it Dry

After putting a generous amount of sealant on the board, allow it to dry completely. When the boards are dry enough, inspect them closely. Look closely to see if there are any spots that are left to be sealed. 

Apply a second coat of sealant to those spots and let them dry. You can also dry the sealant with a hairdryer, but not on high heat.

And that’s it! Sealing the boards is done. After the boards have dried completely, you can use them wherever you want without fear of being damaged.

But while installing them, make sure to put them evenly on the ground. Because it can be quite hard to put tile on uneven floors in the future.

Can You Repair A Damaged Board?

Yes, you can fix a broken board. It is dependent on the extent of the damage to the board. To repair them, first carefully inspect the areas that have been damaged. If the board is damp, you must first dry it.

Let it dry naturally or use a hairdryer to speed up the process. After that, sand the affected area with sandpaper. Clean up the area and seal it with a coat of sealant. Wait for a couple of hours for the sealant to dry. You can reinstall it after it has thoroughly dried.
