Wood finish refers to a protective coating applied to wooden surfaces to enhance their appearance and durability. It can come in various forms, including stains, varnishes, and lacquers, each offering different levels of sheen and color. The primary purpose of wood finish is to safeguard the wood from moisture, dirt, and wear while highlighting its natural grain. Applying a wood finish involves preparation, such as sanding the surface to ensure smoothness. Once prepared, the finish can be applied using brushes, cloths, or spray methods. Proper application not only improves the wood's aesthetic appeal but also extends its lifespan, making it a crucial step in woodworking and furniture making.
