Some interesting facts about the ingredients:

Tung Oil: 

  • Oil is derived from Tung nuts that are grown from small scale producers in China and South America.

  • Oil is extracted via cold pressing and no toxic solvents are consumed or required for extraction.

  • Typically, Tung trees are grown together with other crops and this adds diversity to the land, conserves soil and water resources. 

Pine Tar:

  • Was used extensively by Naval fleets for preserving wood and rope on ships.

  • This tradition continues from the Vikings in Scandinavia, where it has also been employed as an effective additive for paints and oils for preserving wood on building structures.

  • Other products include Pine Tar as a wide spectrum anti-fungicide, as used in veterinary medicine and in hair and skin care products.


Answers to some common questions:


Is a Tung oil finish difficult to apply?
  • There is a tradition of using Tung oil finishes that are very diluted typically at 1:4 ratio with solvents, when used on finely sanded furniture this can require seven or more coatings with the addition of repeated sanding, hand-rubbing, buffing etc. 

  • Allwoods Tung oil can be applied in the traditional manner but without dilution and as few as one coating.

  • We offer several products for simple applications that typically require one coating by simply brushing on.



What is the shelf life in the can?


  • When stored in its original container and kept away from exessive heat, freezing or moisture there is no known limitation except we recommend that the product be used within five years.

  • If there is a large air space in the can the oil may form a crust from oxidation.  If this happens the crust can be removed and the remaining product should be stired and used completely.

  • If the finish has been stored improperly the oil may be strained to remove oil crystals, the oil should be tested on a test sample in case the performance of the product was affected.

How long does a Tung oil finish last on a deck?


  • A slight darkening may develop after several years otherwise the finish does not diminish except from heavy wear.

  • Our products do not peel when used as directed. Most other products begin to peel and fail between 1 and 3 years.  


Can I use Tung oil under a paint or varnish?
  • Yes, there are great advantages from using our Tung oils under other coatings. However, the adhesion of the particular paint or varnish will have to be verified with other manufacturers. 

  • The advantages of using Tung oil as a primer is that it penetrates well, prevents water damage, adds structure and integrity to the wood. 



Can I use Tung oil over pressure treated lumber?
  • Allwood's Tung oil-Pine Tar Outdoor finish works very well on dry pressure treated lumber. 

  • Our tinted formulas work well to hide the dark and uneven tones.

  • A U.S. E.P.A 2006 study recommends using a penetrating oil finish as a barrier to prevent the leaching of harmful chemical compounds in pressure treated lumber.


Are Allwood's oils UV protected? 

  • By many means, yes. 

  • And as far as we know, our products are unique to include Zinc Oxide - a common safe ingredient in baby lotions and suncreens.


Directions for using Allwood's Tung oil finishes:


  • Allwood's Tung oil produces finishes that are durable, easily maintained and highly resistant to staining. It should not be used over surfaces already coated with a protective finish as this prevents adequate penetration into the wood.

  • Allwood's oils are recommended to be used on dry lumber.

  • Softwoods such as Spruce, may need to be naturally weathered or sanded to remove mill glaze to allow for better penetration.


Directions for finely sanded wood, furniture, hardwood floors etc: 

  1. Stir well. With a brush; apply generously spreading evenly with the grain, brushing over several times until the wood is fully saturated. Apply in shade or away from excessive heat.

  2. Buff clean with a lint free cloth before oil forms a gel ( before 30 to 50 minutes ). 

  3. Depending on the wood and desired surface gloss several more coatings may be applied. If more coatings are desired, allow at least 12 hours dry time between applications.

  4. Sand smooth between applications using 220 or finer grit sandpaper.

  5. After applying wipe off excess oil as directed, a final step of hand rubbing may be done in conjunction with step 2.  


Directions for applying on decks and outdoors, primarily on rough surfaces and porous soft woods: 

  1. Clean surfaces well removing loose debris and mold. If a pressure washer is used, the wood must be then dried before applying oil.

  2. Stir well. With a brush; apply generously spreading evenly with the grain, brushing over several times until the wood is fully saturated. Apply in shade or away from excessive heat, a single application is most often sufficient. Wipe off excess oil before gelling if this occurs.

  3. Allow several hours before walking on the surface.
