In a perfect world...  your Waterlox floor would look beautiful  forever... however in the real world we have traffic patterns and children and shoes, and dogs and furniture and all floor finish will scratch and wear over time. Unlike other wood floor  finishes, Waterlox offers a handmade blend of tung oil and resin that penetrates the wood, yielding a rich, hand-rubbed look that is easy to maintain.   When you floors need to be recoated, simply clean and apply a fresh coat of Waterlox.  No sanding is necessary.
