NWFA Maintenance and Recoating
Unlike most floor coverings, wood floors are a long-term investment that, correctly maintained, will last the lifetime of the home. Fortunately for consumers, today’s wood floors offer a wide spectrum of product options that are easy to maintain. Unlike times past, when people had to get down on their knees to buff their wax floors, taking care of wood floors today requires little effort. The routine maintenance involves protecting the finish from scratches and moisture. If consumers avoid both of those things, they’ve got a handle on most of their wood floor care.
