A wood finish is a protective coating applied to wooden surfaces to enhance their appearance and durability. It can come in various forms, such as stains, varnishes, oils, and lacquers. Each type of finish serves different purposes, like adding color, highlighting the wood grain, or providing a waterproof barrier. Applying a wood finish not only improves the aesthetic appeal of furniture and flooring but also helps prevent damage from moisture, UV light, and wear. Properly finished wood can last longer and maintain its beauty, making it an essential step in woodworking and furniture care.
