Unfinished flooring refers to flooring that requires sanding and finishing on site after installation is complete.
This type of solid hardwood flooring is typically 3/4" in thickness, tongue and grooved with end-matching, and available widths range from 2-1/4" to 5" wide. Plank flooring wider than 5" is available, but ordinarily on a special order basis.
Unfinished flooring is usually a square-edged product with some exceptions. Board lengths on manufactured flooring will range from 12" up to 78" on a random length basis.
Unfinished flooring comes as a raw piece of wood (having a few profiles on edges) after a number of processing phases it passes at the flooring factory. No lacquer is applied on it. It will be finished (sanded and lacquered) in the room after installation. Finishing requires specialized craftsmen using specific tools.
It can be laid in a wide range of patterns and finished in a large number of colors and sheens. The job-site sanding allows a smooth surface to be obtained.
