In this short video, you will see how we removed some old OSB subfloors, installed new subfloors and 5” wide hardwood, and also refinished them.

First, we removed the old OSB subfloor. Installed new 23/32” thick plywood subfloor.

Primed the newly installed subfloor with BONA-R540 so that because this will help mitigate potential moisture issues, like cupping originating from below the membrane.

Installed 5” wide 3/4” thick solid unfinished red oak hardwood (select grade) with gluing and nailing method.

Sanded, stained, and refinish the newly installed hardwood floor.

Applied 3 coats of water-based Bona Mega polyurethane with a Satin finish.

The stain color was Dark Walnut. We used DuraSeal stain.
