what is tung oil

Tung oil is a drying oil extracted from the seeds of the tung tree, which is native to China and some other Asian countries. It has been used for centuries as a wood finish due to its flexible, durable, food-safe, and protective waterproof properties. Tung oil dries faster than other oils, making it easier and less time-consuming to apply. It cures to a beautiful matte finish, enhancing the wood grain and producing an antique-style finish on any surface. Tung oil is popular for finishing wood floors, cabinetry, decks, siding, furniture, guitars, and other musical instruments, as well as handmade toys. It is non-toxic, environmentally friendly, and food safe, making it ideal for kitchenware and cutting boards. Tung oil hardens upon exposure to air and is known for its hardness, durability, water resistance, and color stability. It is considered a natural and renewable product, and it does not darken with age. Tung oil is also used for waterproofing and protecting wooden ships, and it has been used as motor fuel during World War II. The oil is available in different forms, including pure tung oil, oil/varnish blends, and wiping varnish, each with its own application and drying characteristics.
