Buff and coat, recoat, and screen and coat are all terms used to describe a light sanding and new finish coat(s) for your wood, bamboo, or cork floors. A buff and coat is a highly recommended maintenance procedure that should be done every 3-5 years, or when the flooring starts to show signs of wear. A buff and coat basically cleans and “roughs-up” the top-layer of finish, removes surface scratches from the old finish, and adds durability and consistency in sheen to the floor. Oregon Select Wood Floors uses a dust-containment system and most projects take less than a day.
