The choice, application and features of tung oil applying

For centuries, tung oil—which is made from the seeds of the tung tree—has been a reliable wood finish. Because of its special qualities, woodworkers and furniture makers love it. When properly applied, tung oil seeps deeply into the wood to create a finish that is both water- and stain-resistant while highlighting the grain’s inherent beauty.

It’s important to select the appropriate tung oil for your project. The best protection and finish can be obtained with pure tung oil, but it can take longer to dry than modified versions. These modified tung oils can expedite the process, which makes them more suitable for short projects. They are frequently combined with other drying agents. You can choose the best solution for your needs by being aware of the differences.

Tung oil application is simple, but it does take time and careful attention to detail. Make sure the wood surface is smooth and clean before beginning. Using a clean cloth, apply the oil in small sections so that it can fully penetrate. For even coverage and a smoother finish, several thin coats are better than one thick coat. Before applying the next coat, let the previous one completely dry.

Tung oil has useful advantages in addition to aesthetic ones. Because of its water-resistant qualities, it is perfect for surfaces that are exposed to moisture, like outdoor furniture and kitchen countertops. Tung oil is a long-lasting finish that can tolerate regular wear and tear since it is flexible and doesn’t break easily. Frequent upkeep, like applying a new coat when the surface becomes dull, can prolong the vibrant and protective appearance of your wood for many years.

Tung oil – what is it

A wood coating tool called tung oil is made from tung wood nuts. This plant produces a large amount of finished product from raw materials because its seeds contain 70% oil. The most popular tung trees in Asia are grown in Canada, Australia, Georgia, and Italy. They are primarily found in China and Japan. It is estimated that over 90,000 tons of oil are produced worldwide.

Tung trees are members of the daily family, can reach a height of 20 to 40 meters, and produce fragrant, white flowers. The fruits are about 6-7 cm in size and have large seeds inside with a thin shell, similar to figs. The juice of tung wood nuts has the potential to be toxic. Plant oil was previously employed for:

• creating coating on red wood furniture;
• protection of wood products from decay, mold;
• fabric impregnation;
• shoes sewing;
• impregnation of boards for ships;
• vomiting in patients;
• manufacturing ointments from burns and abscesses;
• lamp gaskets;
• Soap cooking.

There are no synthetic substitutes for oil, and other oil hoods lack the characteristics that make them ideal for processing wood. Cake that has been squeezed is frequently used to make natural soil fertilizers.

Characterization and composition of the product

The final oil is a viscous yellow liquid with a distinct smell—some find it disagreeable. The following are the material’s primary characteristics:

• good solubility in organic substances-decreasing substances;
• iodine number-154-176;
• washing – 188–198;
• Density – up to 0.945 g/cm. cube;
• hardening temperature – 0 degrees.

Polyunsaturated fatty acids such as linolevo, stearin, palmitin, and eleoStearin make up the majority of the product’s composition. A trace amount of unheated compounds is also present. Tung oil is only used in industry and daily life; it is not a food product, even though it contains components that are beneficial to humans.

Even with a thick layer applied, the tung can dry faster when compared to oil derived from flaxseed seeds. Since the waterproof film is more resilient than linseed oil, the product is frequently referred to as natural varnish.

Properties and use of oil

This technical oil is widely used in paint, varnish, and coating production for wooden surfaces. It is greatly valued for its ability to dry quickly, strengthen wood’s protective qualities, increase wear resistance, and prevent damage from alcohol and moisture. Additionally, experts adore the product for providing a lovely coating that is thin, even, deep, and not brilliant. The process of impregnation becomes so "ingrained" in a tree that it almost becomes a part of it.

The product’s primary areas of application are as follows:

• impregnation of wooden dishes, boards for cutting food, rocks;
• the manufacture of expensive wooden furniture to protect and strengthen beautiful wood pattern;
• protection of houses, baths, arbors, other wooden buildings from fungus, rot, mold, changes in heat and cold;
• processing of antiques and art items for their long preservation;
• restoration of paintings and other products;
• impregnation of high -quality coverage for the floor – boards, parquet;
• processing of equipment, including electrical devices (transformers, generators, wires), automobile parts, spare parts for aircraft;
• impregnation of products in contact with fresh or salty water;
• Making musical instruments.

For wood finishing, tung oil, a natural drying oil made from tung tree seeds, is a flexible and environmentally responsible choice. Understanding the differences between pure, polymerized, and mixed forms of tung oil—each offering distinct drying times and finishes—is important when selecting one. Application is simple: sand in between layers for a smooth, long-lasting finish, apply thin coats, and allow appropriate drying time. Tung oil is an excellent option for both indoor and outdoor projects because of its water resistance and ability to bring out the natural beauty of wood. This makes it a favorite among DIY enthusiasts and woodworkers alike.

Tung oil brands

The most widely used is Italian-produced Borma Tung Oil oil, which comes in 150 ml, 0.5, 1, and 5 liter packages. It costs between 1500 and 1700 rubles per liter. When combined with linen, tens, alkalis, and paints, the product’s cost is significantly reduced. One can process seven square meters of wooden coating with half of the product.

How can I buy a high-quality product? The following are the suggestions:

1. Choose oil, on the package of which is indicated 100% or pure, if you need to perform a thin, natural type of coating.
2. Buy Polymerized Tung Oil oil if you need to make a thick coating with glossy.
3. If the green shade of the product is noted, its quality is reduced, and the most high -quality oil has honey color.

It is preferable for the goods’ raw materials to be grown in the manufacturer’s environmentally friendly area so that complaints about the impregnation’s quality won’t arise.

Ways to use the product

Although the material is not difficult to use, the process of preparing a wooden product requires sufficient time. After being finely ground, it is dried in the air without being exposed to the sun in order to ensure that it is completely dry. It’s likely that the wood is damp with a fungus, and not even a tung hood will shield it.

Prior to submitting the application, the following steps need to be completed:

1. Remove all the villi, particles and pollution, clean from wax if it is available.
2. Check the shade of oil on a small, inconspicuous area of ​​wood (if necessary, you can add tinting to the tool).
3. Large pores on the product should be filled with a special tool if it is advisable.

Using an appropriate brush, apply a thin layer of lubricant to the product. A gentle cloth is used to remove streams and drops, taking care not to damage the tree. Usually applied very thinly, the first layer can be followed by the second layer after it has dried (usually in 8–10 hours) at a temperature as high as 25 degrees.

Skilled professionals recommend lubricating the material with a second layer of tung oil only after letting it sit for a day. You can dilute the product on the first layer of white spirit for even faster drying; subsequent layers function without breeding. Typically, three layers of impregnation are required for fresh wood.

Furniture should have its coating updated once a year to ensure that it lasts for many years. Wax can be applied on top of the coating to give it a shine. As a result, red furniture is frequently used, and tung hoods go well with any arrangement.

When it comes to wood projects, tung oil is a particularly useful and environmentally responsible choice for those looking for a natural finish. Deep protection is provided by its rich, penetrating qualities, which also enhance the wood’s natural grain and create a long-lasting, water-resistant surface. This ensures the longevity and beauty of your wooden items, making it a great option for both indoor and outdoor applications.

It’s important to prepare before applying tung oil. For the oil to penetrate deeply and evenly, the wood must be cleaned thoroughly and sanded to a smooth finish. A smoother, more resilient finish can be achieved by applying the oil in thin, even coats and letting them dry completely between layers. During this process, patience pays off with a superior finish that brings out the wood’s inherent beauty.

Tung oil is a preferred option for woodworkers and enthusiasts due to its distinct qualities, which include its non-toxic nature and ability to withstand moisture. In addition to offering protection, it gives the wood a rich, organic sheen. For anyone wishing to improve and preserve their wood projects in an environmentally friendly manner, this makes tung oil a compelling choice.

In conclusion, tung oil is an amazing product for woodworkers who appreciate both durability and beauty. Although applying it may take some time and attention, the outcome is a stunning, durable finish that highlights the wood’s inherent qualities. Tung oil provides a dependable and appealing answer for your finishing needs, regardless of your level of experience or preference for do-it-yourself projects.
