Refinishing is the process of restoring the surface of furniture, floors, or other wooden items to improve their appearance and extend their lifespan. This typically involves sanding down the existing finish, repairing any damage, and applying a new coat of stain or sealant. The goal is to enhance the natural beauty of the wood while providing protection against wear and tear. Common items that undergo refinishing include hardwood floors, tables, and cabinets. This technique can also be applied to metal and plastic surfaces, though the methods and materials may differ. Refinishing is a cost-effective way to revitalize old items instead of replacing them.
