Tung Oil, or Chinese Wood Oil as it’s sometimes called, is a natural oil derived from the seed of the nut of the tung tree. The jury is out as to whether it can spark a nut allergy.
Tung Oil air dries to form a tough, hard film that has a fairly strong amber tint. Because it doesn’t have any solvent or driers in it it can take a while to dry, and dependant on conditions this can be up to a week although 48 hours is more common. As with most finishes a thinner coat will dry quicker.
Normally applied with a brush or cloth.
