Watco Teak Oil Spray Finish is specially formulated for dense wood surfaces including teak, mahogany and rosewood. This oil-based formula enhances the natural look and feel of wood, penetrating deep into wood pores to create the rich, warm glow of a hand-rubbed finish. Ideal for outdoor or indoor furniture and marine surfaces (above the water line) such as wood boat decks, cabinets, and rails. Not recommended for use on patio decks, interior floors or marine use below the waterline.
