Recoating is a more intensive maintenance process than polishing because it uses a buffer to lightly scuff the existing finish to remove ground-in debris that polishing can’t reach. After buffing, the existing finish is recoated with another layer of finish. This is sometimes called a screen and recoating, referring specifically to the process of recoating the wood with a new coat of polyurethane, which helps protect the wood beneath. Depending on the type, style, and brand of hardwood floor, the manufacturers of your hardwood floor can recommend the type of polyurethane, the suggested amount to use in the recoat, and the proper care and cleaning after the recoating process is completed. This process is not quite as invasive and expensive as refinishing your hardwood floors, presenting an attractive middle-of-the-road option for many homeowners and businesses.
