Pure tung oil is a type of drying oil derived directly from the seeds of the tung tree without any additives or distillation processes. It is important in woodworking due to its durability, versatility, and eco-friendliness.
It forms a tough, flexible layer that protects the wood from scratches, spills, and the damaging effects of UV rays. It is also incredibly versatile, as it can be used on a cutting board, a piece of furniture, or a wooden boat.
Lastly, pure tung oil is non-toxic, biodegradable, and safe for food contact surfaces, making it a favorite among woodworkers who care about the environment and their health.
The Difference Between Tung Oil and Pure Tung Oil
Let’s clarify a common misconception: tung and pure tung oils are different. Yes, they both originate from the seeds of the tung tree, but the similarities pretty much end there.
Tung oil, often found in hardware stores, is usually a blend of raw tung oil, mineral spirits, and other additives. This concoction is designed to make the oil easier to apply and speed up drying.
However, this convenience comes at a cost. The additives dilute the oil, reducing its protective qualities and potentially introducing harmful chemicals.
On the other hand, pure tung oil is just that – pure. It’s the raw, uncut version, free from additives or distillates. It’s a bit more labor-intensive to apply and takes longer to dry, but the result is well worth the effort.
The Journey from Seed to Bottle: Processing Methods and Their Impact
The difference between tung and pure tung oil largely depends on their processing methods.
Tung oil undergoes “polymerization,” which involves heating the oil to high temperatures. This process thickens the oil and makes it dry faster when applied to wood. However, it also strips away some of the oil’s natural properties.
Pure tung oil, in contrast, is cold-pressed from the seeds of the tung tree. This method retains all of the oil’s natural characteristics, including its deep-penetrating, water-resistant, and protective qualities.
A Test of Time: Quality and Durability of Both Oils
Pure tung oil takes the cake when it comes to quality and durability. Its ability to penetrate deep into the wood provides long-lasting protection from the inside out. It’s resistant to water, alcohol, and food stains, making it an excellent choice for kitchenware and outdoor furniture.
While still offering a decent level of protection, Tung oil falls short in comparison. The additives and distillates reduce its durability, making it less resistant to scratches and stains. Over time, the finish may also become brittle and start to crack.
The Benefits of Pure Tung Oil
Pure tung oil offers many benefits, making it a standout choice for wood finishing.
Firstly, it’s incredibly durable. It forms a tough, elastic finish that protects the wood from the wear and tear of daily life. It’s like a shield, guarding your wooden pieces against everything from water spills to UV rays.
Secondly, pure tung oil is safe and eco-friendly. It’s non-toxic, biodegradable, and safe for food contact surfaces. This makes it an excellent choice for kitchen utensils, cutting boards, and children’s toys.
Lastly, pure tung oil enhances the natural beauty of the wood. It penetrates deep into the wood fibers, highlighting the grain and giving the wood a rich, warm glow. It’s like a beauty treatment for your wood, bringing out its best features.
The Guardian of Wood: Protective Properties of Pure Tung Oil
One of the standout qualities of pure tung oil is its protective properties. When applied to wood, it forms a hard, water-resistant layer that safeguards it from moisture, mildew, and UV damage. It’s like a raincoat, a sun hat, and a suit of armor all rolled into one.
The Beauty Enhancer: How Pure Tung Oil Brings Out the Best in Wood
Pure tung oil doesn’t just protect your wood; it beautifies it. It seeps into the wood fibers, enhancing the grain and imparting a warm, lustrous glow. It’s like a spotlight, illuminating the wood’s natural beauty for all to see.

The Flip Side: Potential Downsides of Using Tung Oil
As with everything in life, tung oil isn’t without its drawbacks. While its benefits are numerous, it’s only fair that we shed light on the potential downsides.
Firstly, tung oil can be a bit of a diva regarding drying time. Unlike its synthetic counterparts, tung oil takes its sweet time to dry. This means you must be patient and allow ample time between coats.
Secondly, tung oil requires a bit more elbow grease to apply. It’s not as simple as slapping on a coat of paint. You must apply it in thin layers, buffing each until fully absorbed.
Lastly, pure tung oil has a distinct smell. While not unpleasant, it can be quite strong during application and drying.
Turning Lemons into Lemonade: Mitigating the Disadvantages
Before you get discouraged, let me assure you that these disadvantages are not deal-breakers. In fact, they can be easily mitigated with a little bit of knowledge and the right approach.
To speed up the drying process, ensure your workspace is well-ventilated and the temperature above 50 degrees Fahrenheit. You can also consider adding a drying agent, like cobalt siccative, to your tung oil.
As for the application process, consider it a labor of love. Yes, it requires more effort, but the result is well worth it. Plus, applying and buffing the oil can be quite therapeutic!
If the smell of tung oil is a concern, rest assured that it dissipates once fully dried. You can also use a respirator during application if you find the smell too strong.
How to Apply Pure Tung Oil
Applying pure tung oil is more of an art than a science. It requires patience, precision, and a bit of elbow grease. But don’t worry, I’ve got you covered. Here’s a step-by-step guide to help you achieve the best results.
- Preparation is key: Start by sanding your wood piece until it’s smooth. This will allow the oil to penetrate more deeply.
- Less is more: Apply a thin layer of tung oil using a clean, lint-free cloth. Remember, applying several thin coats rather than one thick one is better.
- Buff, buff, buff: After applying the oil, wait 15-30 minutes, then buff the surface with a clean cloth. This will help the oil penetrate the wood and remove any excess.
- Patience is a virtue: Allow the oil to dry for at least 24 hours before applying the next coat.
- Repeat for best results: Repeat the process until you’ve achieved the desired finish. Typically, 3-5 coats should do the trick.
The Waiting Game: Drying Time and Factors Affecting It
One of the most common questions about tung oil is, “How long does it take to dry?” The answer, my friend, depends on a few factors.
Firstly, the temperature and humidity of your workspace can significantly affect the drying time. As a rule of thumb, the warmer and less humid the environment, the faster the oil will dry.
Secondly, the thickness of your application will also play a role. Thinner coats dry faster than thicker ones.
Lastly, the type of wood you’re working with can also influence the drying time. Some woods absorb oil faster than others.
So, while it’s hard to give a definitive answer, you can expect pure tung oil to dry within 24-48 hours under optimal conditions.
Pure Tung Oil vs. Other Oils
