Wood stains are liquid products used to enhance the color and appearance of wood surfaces. They penetrate the wood fibers, allowing the natural grain to show through while adding a desired hue. Stains come in various types, including oil-based, water-based, and gel stains, each offering different application methods and drying times. Applying wood stains can protect the wood from damage and wear, making it suitable for furniture, flooring, and outdoor structures. Proper preparation, such as sanding and cleaning the surface, is essential for achieving an even finish. After staining, a protective topcoat may be applied for added durability.
