What's the difference between prefinished and unfinished flooring?
Prefinished: advantages are faster and easier installation, minimal disruption to your home, fast cleanup time and usually less expensive labor costs because sanding, staining, and coating are performed in the factory. Also, you usually get an extended warranty with prefinished flooring and finish that is very scratch resistant.
Unfinished: Advantages are the availability of more wood species, widths, and cuts that can be matched to existing wood floors. Also, unfinished flooring allows for custom onsite sanding, staining, and coating with a protective sealant after installation to achieve a beautiful unique floor.
