Things You'll Need
Wooden match sticks
Particle board is manufactured board made from wood scraps, saw dust and glue. It's pressed and heat-treated to create a product used in home construction and furniture production. Knowing how to repair particle board will save you the cost of replacement, as well as the time and frustration involved. Regardless of what purpose the particle board is intended for, knowing what tools to use and how to use them keeps you on schedule.
Stripped Screw Holes
Remove the existing screws.
Use a blow dryer to blow debris out of the screw holes.
Fill the hole with wood glue.
Snap the burn edges off of wooden match sticks off and push the wooden sticks into the glue.
Screw the screws back into the glue. The screws push the wooden sticks into the gaps, filling the stripped screw hole and allowing the screw to hold the particle board in place.
Squirt wood glue into the cracks.
Push the glue fully into the cracks and crevices with a piece of stiff paper like card stock.
Cover the the edge with plastic wrap. Place a scrap piece of wood on either side of the particle board and clamp together. The wood prevents the clamps from damaging the particle board. Let it dry overnight before removing the clamps. If the glue is still damp, replace the clamps and wait another night.
Use wooden match sticks rather than toothpicks. The wooden match sticks are softer and will be pushed into gaps better than toothpicks.
Always wear protective eye wear when working with particle board.
