Particle Board Under Countertop

The wood particles can be made from practically any part or kind of wood such as trimmings shavings and sawdust from manufacturing of plywood or other wood products.
Particle board under countertop. Particle board is made from dry wood particles that are sprayed or dusted with a binder resin then bonded together with heat and pressure. The screws can t grab hold and i could see bigger chunks of particleboard coming loose as the dishwasher door is opened and closed. It is easier to work with and cheaper.
I have a typical laminate kitchen counter top which is built of particle board under the laminate. The edges are square and consistent. Apply a coating of carpenter s glue on one of the particle boards with the use of a trowel and set the other piece of particle board on top of it.
The particle board used as a substrate in most countertops is notoriously susceptible to moisture damage. The bottom edge at the front where it hangs over the cabinets is bare particle board. Step 1 cutting the particle board cut a couple of pieces of particle boards that are 2 inches wider that the countertop you are intending to cover.
The section over the dishwasher is crumbling and releasing wood particles all the time due to the steam from the dishwasher. Once exposed it absorbs moisture quickly and loses its ability to hold a laminate bond.
