Understanding Tung Oil
As a woodworker, I have come across many types of finishes. One of the finishes that I have found to be very useful is tung oil. Tung oil is a natural drying oil that is extracted from the seeds of the tung tree. It is a popular choice for finishing wood because it is easy to apply and provides a beautiful, natural-looking finish.
Pure tung oil is the most natural form of tung oil. It is a distillate that is made by pressing the seeds of the tung tree. Pure tung oil is non-toxic and is safe to use on food-contact surfaces. It is also resistant to water and can help to protect wood from moisture damage.
Tung oil is a drying oil, which means that it dries by reacting with oxygen in the air. This process can take several days to several weeks, depending on the temperature and humidity. Once the tung oil has dried, it forms a hard, protective layer on the surface of the wood.
One of the benefits of tung oil is that it is easy to apply. It can be applied with a brush, a cloth, or a sprayer. When applying tung oil, it is important to apply thin coats and to allow each coat to dry completely before applying the next coat. This will help to ensure that the tung oil dries evenly and forms a smooth finish.
Overall, tung oil is a great choice for finishing wood. It is natural, easy to apply, and provides a beautiful, natural-looking finish. If you are looking for a natural and durable finish for your woodworking projects, I highly recommend giving tung oil a try.
Tung Oil Vs Other Finishes
When it comes to finishing wood projects, there are many options available, including linseed oil, varnish, shellac, and tung oil finishes. Each of these finishes has its own unique characteristics, advantages, and disadvantages. In this section, I will compare tung oil finishes to other popular finishes.
One of the most significant advantages of tung oil finishes is their durability. Tung oil is a natural oil that penetrates deeply into the wood, which makes it waterproof and resistant to wear and tear. In comparison, linseed oil and shellac are less durable and require frequent reapplication.
Varnish is also a durable finish, but it can be challenging to apply evenly, and it tends to yellow over time. Tung oil finishes, on the other hand, do not yellow and maintain their natural color for a long time.
Tung oil finishes are known for their waterproofing properties. They create a protective layer on the surface of the wood that repels water and prevents it from penetrating the wood. This makes tung oil finishes ideal for outdoor projects and items that will be exposed to moisture.
Linseed oil and shellac are not as waterproof as tung oil finishes, and varnish can be waterproof, but it requires multiple coats to achieve the same level of protection.
Ease of Application
Tung oil finishes are relatively easy to apply, and they dry quickly. They can be applied using a brush, cloth, or spray gun. In comparison, linseed oil and shellac can be challenging to apply evenly, and varnish requires careful preparation and multiple coats.
Overall, tung oil finishes are an excellent choice for those looking for a durable, waterproof finish that is easy to apply. While other finishes such as linseed oil, varnish, and shellac have their own unique advantages, tung oil finishes offer a combination of durability, waterproofing, and ease of application that is hard to beat.
Application of Tung Oil Over Paint
If you’re looking to apply tung oil over paint, there are a few things you should keep in mind. First, it’s important to note that tung oil is typically used on bare wood surfaces. However, it is possible to apply tung oil over a coat of acrylic paint.
Before applying tung oil over paint, it’s important to make sure the painted surface is clean and free of any debris. This can be achieved by sanding the surface with a fine-grit sandpaper, such as 150-grit. Once the surface is sanded, it should be wiped down with a lint-free rag to remove any dust or debris.
When applying tung oil over paint, it’s important to use a bristle brush. This will help to ensure that the oil is evenly distributed and will help to avoid any streaks or uneven spots. It’s also important to use a lint-free rag to wipe away any excess oil after application.
If you need to reapply tung oil over paint, it’s important to first sand the surface with steel wool to remove any existing finish. Once the surface is sanded, it can be wiped down with a lint-free rag to remove any dust or debris before applying a new coat of tung oil.
Overall, applying tung oil over paint can be an easy process if you follow the proper steps and use the right tools. Just be sure to take your time and follow the instructions carefully to ensure the best results.

Another great thing about tung oil is its versatility. It can be used to create a variety of finishes, from a clear, matte finish to a lustrous, satin finish. It can also be used to create a transparent, wet finish that really brings out the grain of the wood.
But perhaps the best thing about tung oil is its durability. It creates a hard, protective layer on the surface of the wood that is resistant to water, stains, and scratches. And, unlike other finishes that can peel or crack over time, tung oil actually becomes more beautiful with age.
Overall, I think tung oil is a great choice for anyone looking to bring out the natural beauty of wood. It is versatile, durable, and creates a finish that is hard to beat.
Maintenance and Care of Tung Oil Finish
As someone who has used tung oil over paint, I can attest to its durability and longevity. However, like any finish, it requires proper maintenance and care to keep it looking its best. Here are some tips to help you maintain your tung oil finish:
Moisture and Water Resistance
Tung oil is naturally water-resistant, making it an excellent choice for surfaces that are exposed to moisture. However, it’s important to note that tung oil does not make a surface waterproof. If your surface is exposed to standing water or prolonged exposure to moisture, it’s important to wipe it dry as soon as possible to prevent damage to the finish.
While tung oil is resistant to water, it can be affected by extreme weather conditions such as high humidity, extreme heat, and freezing temperatures. If your surface is exposed to these conditions, it’s important to take measures to protect it, such as using a soapstone sealer or traditional brown wax.
To maintain your tung oil finish, it’s important to periodically reapply a coat of oil. The frequency of application depends on the level of use and exposure to the elements. I recommend using walnut oil or boiled linseed oil, as they both work well with tung oil and provide excellent protection.
To clean your tung oil finish, use a mild soap and water solution. Avoid using harsh chemicals or abrasive cleaners, as they can damage the finish. If your surface becomes scratched or scuffed, you can use fine grit sandpaper to smooth out the surface, followed by a coat of tung oil to restore the finish.
If you want to add an extra layer of protection to your tung oil finish, you can apply a coat of wax. I recommend using shellac wax, wax flakes, or Myland’s wax. Apply the wax with a soft cloth, let it dry, and then buff it with a clean cloth to achieve a smooth, glossy finish.
By following these tips, you can keep your tung oil finish looking beautiful for years to come.
