Sanding clears chunks of the damaged wood and the faded polyurethane. It removes the layer of the wood floor that absorbs the stain. After sanding, we re-stain the wood and seal with an additional layer of polyurethane. Sanding addresses noticeable defects in the wood floor. It also allows you to change the colour of your wood floor.
Buffing addresses the polyurethane and does not the wood. The condition of your wood floor will determine the wood restoration method to be used.
