Wood stain
Wood stain is used in woodworking, construction, and architectural finishing to modify the color and appearance of wood while allowing the grain pattern to remain visible. Unlike paint, which forms an opaque surface coating, stains are typically formulated to penetrate wood fibers or lightly coat the surface, enhancing natural texture rather than concealing it.
Wood stains are used for both decorative and protective purposes in interior furniture, flooring, cabinetry, and exterior structures such as siding, decks, and fences. Modern formulations may incorporate water repellents, ultraviolet stabilizers, and preservatives intended to slow weathering caused by moisture and sunlight exposure.
Stains are commonly categorized by carrier type, including oil-based, water-based, alcohol-based, and gel stains, each offering different drying characteristics, penetration behavior, and maintenance requirements.
