Wood finishes are protective coatings applied to wooden surfaces to enhance their appearance and durability. They come in various types, including varnish, stain, lacquer, and oil. Each type serves a different purpose, such as adding color, providing a glossy finish, or protecting against moisture and wear. Applying a wood finish involves preparing the surface, choosing the right product, and using appropriate techniques for application. Proper finishing can highlight the natural beauty of the wood grain while safeguarding it from damage caused by sunlight, water, and scratches.
