The longevity of hardwood refinishing is determined by the quality of the polyurethane or oil-based finish, the expertise of the sanding process, and the subsequent care of the floor. Regular light maintenance, such as sweeping with soft-bristled brooms and utilizing entrance mats to trap abrasive particles, preserves the finish. Factors like pet activity and foot traffic accelerate wear. When the surface finish shows signs of significant dulling or scratching, professional intervention is required to restore the floor.
