Can You Install Hardwood Flooring Over OSB Board?

OSB is strong and durable, but it is not as smooth as plywood. Therefore, it is not recommended to install hardwood flooring directly over OSB. However, you can still install hardwood flooring over OSB by following these steps:

Install a layer of plywood over the OSB.
Sand the plywood smooth.

Follow these steps to install the plywood:

Apply a thin layer of construction adhesive to the OSB.
Place the plywood over the OSB and nail it down.
Be sure to space the nails evenly and countersink them slightly below the surface of the plywood.
Repeat this process until the entire floor is covered with plywood.

How to Sand the Plywood Smooth

Sander
