Wood stain is a type of finish used to enhance the appearance of wood surfaces. It penetrates the wood fibers, adding color and depth while allowing the natural grain to show through. Stains come in various shades and can be oil-based or water-based, each offering different benefits in terms of drying time and ease of application. Applying wood stain is a straightforward process that typically involves cleaning the wood, applying the stain with a brush or cloth, and allowing it to dry. After staining, a protective topcoat, such as polyurethane, is often added to safeguard the wood from damage and wear.
