Two-part epoxy repair putty
Epoxy bonding agent
Manufacturers make particle board by combining sawdust, wood chips and small wood scraps with adhesives and then press the mixture into a flat sheet. Particleboard is an inexpensive alternative to real wood. It is available in a variety of densities, which refers to its strength and durability. Regardless of the density, particleboard is not impervious to holes and damage. Generally, a hole in particleboard will continue to chip until you repair it.

Remove loose bits and pieces of particleboard with your fingers. Sand the perimeter of the hole with a rasp to refine jagged edges. Brush away sanding dust.
Mix two-part epoxy repair putty. Work the putty with your hands until it is pliable.
Apply an epoxy-bonding agent to the inner edges of the hole. The bonding agent acts as a bridge between the particle board and the epoxy-putty ensuring adhesion.
Fill the hole in with the epoxy putty. Press the putty into the rim of the hole tightly and firmly, sitting slightly higher than the surface. Fill the hole with one large piece of putty rather than adding small pieces or layering the putty into the hole.
Allow the putty to dry completely, generally one to two hours. The putty will dry to a hard and fixed state.
Sand the epoxy putty smooth and flush with medium-grit sandpaper. Follow by sanding with fine-grit sandpaper to achieve a smoother look and feel.
A rasp is a long, rough metal file, used to shape wood and wood products. Wear disposable gloves when working with epoxy repair putty.
