As one of the most impervious, durable oil finishes, Tung Oil is the choice for many woodworkers. This Tung Oil, also known as China Wood Oil or Nut Oil, from Behlen is pure unmodified Tung Oil with no adulterating agents such as varnishes, soy oils for urethane additives. The advantage is a consistent quality finish that will build up to be extremely hard and durable. That means resistance to water, caustic acids, heat and mildew. What else could you ask for in a finish? How about ease of application? Well, simply apply with a rag and rub thoroughly. Wait as least 24 hours and apply a second coat if desired. Since Tung Oil is so durable, it is used to manufacture many types of varnish and can be used to make your own finishes. Because this Tung Oil is so concentrated, it may be thinned with up to four parts Mineral Spirits to one part Tung Oil before application. Behlen's Tung Oil should be your choice for a long-lasting tough oil finish.
