How to Apply Tung Oil. Tung oil is a type of natural drying oil commonly used as a finish in woodworking projects. When applied to a raw surface, the oil hardens to protect and add luster to the wood. After sanding and cleaning the wood...
To get the maximum protection, apply 3 coats of full-strength tung oil but you can always apply more. I applied more coats until the oil was not penetrating into the wood after letting it sit. As an optional step, you can thin the first coat of tung oil by 50% oil to 50% mineral spirits. This will greatly increase its penetration into the wood.
Pure Tung oil is a drying oil that’s extracted from the seed of the tung tree, which is native to China and a few other Asian countries. The oil has been used for centuries as a water-resistant finish for boats and other wooden objects, as well as to finish stone.
Use any clean, lint-free rag to apply tung oil. If you use a rag that has rough-cut edges, be sure to fold the rag so the rough edges are held in your hand and are not on the wood surface, since any loose wood fibres may catch the edge of your cloth and leave troublesome lint behind.
Applying tung oil to wood countertops, cutting boards or wood bowls is very easy. First only use 100% pure tung oil without thinning. Apply liberally with a brush or rag. Using circular rubbing motions will help the oil penetrate. Finish by using a rag to remove any excess by lightly rubbing in the direction of the wood grain.
A tung oil or Chinawood oil finish is usually applied to unfinished wood, but works just as well over a wood stain. Tung oil has a warm, amber color that gives wood a classic hand-finished look.

Tung oil or China wood oil is a drying oil obtained by pressing the seed from the nut of the tung tree (Vernicia fordii).Tung oil hardens upon exposure to air, and the resulting coating is transparent and has a deep, almost wet look. Used mostly for finishing / protecting wood, after numerous coats the finish can even look plastic-like.
Do not apply or leave fresh tung oil on the surface in direct sunlight. This will flash cure it on the surface and turn it white and hazy. Do not sand between coats of tung oil. This is an application technique for tung oil varnishes, not pure tung oil. Do not use Pure Tung Oil over oil-based sealers, stains, and finishes.
