How To Use
Preparation Ensure the wood surface is bare: remove any wax finishes with Liberon Wax and Polish Remover and any varnish finishes with Paint Stripper. Clean, dry and ensure the surface is dust free.
Application Apply Liberon Pure Tung Oil using a brush or lint-free cotton cloth. For ease of application dilute the first one or two coats with up to 50% white spirit. Allow the oil to penetrate for 20 to 30 minutes then wipe off the excess oil using a clean lint-free cloth. Allow to dry for 24 hours between coats.
Apply further coats of Liberon Tung Oil as above, reducing the amount of white spirit used with subsequent coats. Again allow 24 hours to dry.
Apply the last one or two coats of Liberon Tung Oil undiluted, as in previous applications. After the final coat has been applied and excess removed leave for 24 hours and wipe over again to aid drying and remove any oil that may have surfaced. We recommend a minimum of 4 coats; more coats will be required for porous or external surfaces. For best results, gently rub with Liberon Ultra Fine Steel Wool (0000) between coats.
Leave for a few days before use to allow the Liberon Pure Tung Oil to dry fully. Furniture items may be finished with Liberon Black Bison Wax for an improved lustre. Maintainance
Pure Tung Oil must be maintained on a regular basis. Apply at least once or twice a year or more if required, depending upon exposure to weather and usage. On exposed timber it is important to apply sufficient coats of oil to give the initial protection. Important Oil finishes bring out the natural colours of timber. A wet surface will be an indication of the final colour. Always test product on a spare surface or inconspicuous area for colour, compatibility and end result.
Precautions · Tung Oil is extracted from nuts and may cause an allergic reaction.
· Oily cloths can self combust. Do not leave impregnated cloths in bundles. Before discarding lay them flat outside to dry to avoid a fire hazard.
· If the excess is not removed and the surface becomes sticky, wipe with white spirit to remove the sticky film and allow to dry before continuing.

WHAT IS TUNG OIL AND WHERE ON EARTH DOES IT COME FROM?
Tung oil is made from pressed seeds from the nut of the tung tree. The tung tree, native to China, is named for its heart-shaped leaves because “tung” is Chinese for “heart.” In the 14th century, Chinese merchants were noted for using tung oil to waterproof and protect wooden ships from the eroding powers of the sea. There are even mentions of tung oil appearing in the writings of Confucius in around 400 B.C. For these reasons, it is also sometimes referred to as “China wood oil.”
Pure tung oil is considered a drying oil much like linseed, safflower, poppy and soybean oil and is known to have a slightly golden tint. Tung oil, which is actually a vegetable oil, is considered the best penetrating drying oil available due to its unique ability to wet the surface, allowing it to penetrate even the densest woods. Unlike linseed oil, it will not darken with age.
INTERESTING THINGS TO KNOW ABOUT TUNG OIL:

• Completely natural and renewable, pure tung oil has gained recent popularity
among the environmentally conscious.
• Inherently resistant to disease and insects, tung trees require no fungicides

WHAT DOES A TUNG TREE LOOK LIKE?
It is a small deciduous tree that grows up to 40 feet tall with smooth bark and a branchy head. Its leaves are dark green and glossy with blades 3-13 inches wide. The tung tree has flowers that range in size from 1-3 inches in diameter with petals that are white tinged with red and yellow. Each nut or fruit contains 3-7 large seeds.
HOW DOES A TUNG TREE GROW?
The tung tree’s official botanical name is Aleurites fordii. It thrives in moist, well-drained, slightly acidic soil. These hearty, fast growing trees mature to bear fruit in their third year and yield commercial quantities at four to five years of age. Maximum production occurs in the tenth to twelfth years of growth, with trees expected to be commercially productive for at least 20 years after optimum production has occurred.
In the Northern Hemisphere, tung tree nuts grow in clusters and fall to the ground from late September through November. The fruits are left for a few weeks to dry and cure. Tung oil is produced by harvesting these nuts and separating the nuts from their hard outer shells. Then the transparent oil is squeezed from the seeds inside.
Dried and pressed nuts yield about twenty percent oil. Under favorable conditions an acre of tung trees will produce about two tons of tung nuts and yield about 100 gallons of raw tung oil annually.
