Sutherland Welles Ltd.
Pure High Lustre Polymerized Tung Oil

The perfect choice when creating the finest hand-rubbed finish.

Polymerized Tung Oil finishes are hard yet flexible, waterproof and impervious to alcohol and many food acids. As a penetrating oil, it allows wood to continue its aging process and to develop its patina. The wood's rich natural color is enhanced while the wood is nurtured with Polymerized Tung oil.

Sutherland Wells has developed a unique process of polymerization involving "cooking" a natural vegetable oil, called tung oil, to its maximum thermal threshold. This sophisticated polymerization process develops both the ultimate hand-rubbed sheen and improves the curing. The result is that their High Lustre Polymerized Tung Oil produces a quality finish without adding varnishes or urethanes.

Polymerization, when done right, is an expensive process. When done properly it produces tung oil that has long-lasting durability and a gorgeous sheen. But, if the process isn’t well controlled the oil solidifies and the entire batch is lost.

The difficulty and expense of a proper tung oil polymerization process leads most companies to formulate their tung oil with modifiers. This simplifies polymerization, but it adds to the toxicity of the finish and inhibits the penetration of the oil into the wood. It also results in a finish that takes a long time to dry and cure. As far as long-term durability -- with the cheaper process over time the varnishes and urethanes discolor and deteriorate, degrading the finish.

The Sutherland Wells' polymerization process does not add toxic materials to the tung oil finish and it reduces the curing time. The driers used in their High Lustre Polymerized Tung Oil have been researched and found to be of the lowest toxicity available.

Polymerized Tung Oil must also be formulated with solvents to thin the oil to maximize its workability and penetration. Sutherland Wells High Lustre Polymerized Tung Oil uses the purest solvents available, reducing the environmental impact and minimizing a finisher’s exposure to toxic fumes and chemicals. When the formulation is complete, the result is a Polymerized Tung Oil finish that is both finisher-friendly and environmentally responsible.

Surface Preparation & Application

The wood should be sanded to 320 grit and be free of dust and foreign matter. Application should be done between 55 degrees F and 75 degrees F with the humidity below 65%. Mix only enough High Lustre Polymerized Tung Oil with turpentine (1 to 1 ratio) to yield enough liquid for your first coat. Apply liberally with a natural bristle brush and let stand for 15 minutes. Wipe with a clean cloth and let cure for 8 hours. Buff with a fine woven pad and wipe with a clean cloth. Then apply undiluted High Lustre Polymerized Tung Oil thinly with a natural bristle brush.

Allow 10-15 minutes for the Polymerized Tung Oil to penetrate, and then use a clean rag or cheesecloth to wipe the remaining Polymerized Tung Oil off using a circular motion. Keep changing the area of the rag to a dry spot to pick up all traces of the Polymerized Tung Oil. Your final wipe should be in the direction of the grain of the wood. Allow 12-24 hours for the coat to both dry and cure. Successive coats are applied using the technique described above.

If the surface should tack-up before you wipe it off, simply apply more Polymerized Tung Oil and wipe off immediately and thoroughly.

Cure Test: To avoid STREAKING AND FLASHING in the finish perform the cure test prior to applying a coat of finish. Streaking and flashing are the appearance of dull spots in the finish. This occurs when moisture is trapped in the layers of finish due to insufficient curing time. Push your finger tips against the grain of the wood over various parts of the surface to be re-coated. If they glide easily over the surface – you are ready to apply your next coat. If there is any "grab"or friction felt, you will need to wait longer for this coat to cure. Repeat the cure test every two-four hours until your fingers slip easily across the surface.
