Is Tung Oil food safe. Pure Tung oil is food safe once it has been cured. It is the go to finish for wooden countertops, wooden toys, table tops etc. It enhances the color of wood, offers superb protection, and is friendly to the environment.

Natural tung oil comes from tung tree nuts and is a perfect food-safe wood finish. However, some Tung oil products contain heavy metals unfit for human consumption.

It would help if you were cautious when buying a tung oil finish. Unless a product contains such terms as “100% Pure Tung oil,” that wood finish may be anything else but a food safe finish.

Read on to know everything you need to know about Tung oil finishes.

What is Tung Oil?

Tung oil is derived from Tung-tree nuts that originated in China and South America. It is a natural drying oil that people have used for centuries to finish wood, such as butcher blocks and cutting boards, if not used as chopping.

It improves the color of wood, provides excellent protection, and is environmentally friendly.

How many coats of tung oil do you need to apply for a professional finish?

The majority of projects will need four to six coats. The more coats you apply, the darker and more glossy the finish will become, and the more protected the surfaces will be.

Treating your wood with Tung oil is a continuous process because it takes days or weeks to cure, depending on the humidity levels. The more coats you apply, the longer it will take to dry and cure.

Types of Tung Oil – How to Pick the Correct Type of Tung Oil Finish

Three types of tung oil finishes are penetrating pure tung oil, varnish blends, and wiping varnish. They are both durable, water resistant, and offer a gorgeous color.

Pure Tung Oil

Tung oil, or Chinese wood oil, is one of the world’s most widely used and well-known wood finishes. It is completely food safe.

Its use dates back thousands of years in Asia, and it’s been used as both a sealant and an adhesive as well as an ingredient in paints and finishes. It’s also one of the most sought-after antique furniture finishes due to its durability and beautiful lustre.

It creates a beautiful, natural lustre that enhances the wood grain. Tung Oil is an entirely natural product, making it one of the best food-safe finishes when cured for thirty days. It’s durable and hardwearing, making it ideal for floors and furniture.

It is easy to apply and requires no special equipment or skills. The only few downsides of PureTung Oil are that it is a drying oil, meaning that it will harden, and cracks might form if it’s not applied correctly.

It also takes a long time to cure, so you need to have the patience of a saint when using it. Pure Tung oil can also be quite expensive, depending on where you purchase it.

Varnish/ Oil Blends And Wiping Varnishes

varnish blends were developed to hasten the pure tung oil’s drying times and make application easier. It achieves this by incorporating artificial resins and solvents to keep the resins in solution.

If the label says “contains petroleum distillates,” know it is one of these wood finishes.

The differences between them are subtle. Blends are made up of oil (or oils) blended with a varnish. Wiping varnishes are ordinary varnishes that have been significantly thinned to be applied with a dry cloth. The resin binds all of the oils in a varnish.

Sadly, manufacturers rarely use the terms “oil/varnish blends” and “wiping varnishes” to classify their tung oil products. Please read the application instructions carefully to tell them apart.

It’s a blend varnish if the instructions advise you to wait specific minutes after applying the finish before wiping up or buffing off the excess material. If you don’t wipe up the excess oil, it will wrinkle and require sanding. 

If the instructions do not specify a second wipe, it is a wiping varnish, which will dry smooth and hard. You won’t need to sand.

Which Tung Oil Finish Should You Use to avoid Cross-contamination?

Pure Tung Oil is the go-to finish to use on surfaces where food safety is a big concern. Here’s why

It’s a natural product– It is entirely additive-free, making it non-toxic and safe to use on different items. It prevents the wood from drying and helps it repel water, protecting it from rotting. It is suitable for sealing bare and unfinished wood, preventing marking and discoloration.

It is ideally food safe– Pure Tung Oil is a natural product, therefore a fantastic choice for food prep surfaces, such as kitchen surfaces, children’s furniture, and toys, and exterior wood surfaces such as decking.

Water-resistant – Finishing kitchen surfaces and cutting boards with Pure Tung oil will give them water resistance. It is helpful for cutting boards because they are continuously exposed to water.

It is scratch-resistant – Tung oil creates a protective coating on your cutting board that protects it from scuffs, dents, and cracks, letting you use them for many years.

It gives the surfaces a beautiful finish – Although Pure Tung oil is clear and does not yellow with time like other finishes, it also has a glossy finish that makes your wooden countertops stunning.

It’s effortless to Apply – Tung oil is simple to apply and reapply, which adds an excellent level of ease to your projects.

Although Pure Tung Oil is simple to apply with a foam brush, your hand takes longer to dry and is pricey.

Factors to Consider Before Buying Tung Oil as a Food-safe Finish

Before spending a dime on any Tung Oil product, consider the following factors

Budget

How much are you willing to spend on the product? Pure tung oil is pricey depending on where you purchase it.

If your project is big and surface porous, you’ll need a lot of oil, meaning you’ll spend a lot. You may consider Tung oil blends and varnishes as they are more affordable.

The Size of Your Project

How big or small is your project? If your project is enormous, buy the gallon-size product instead of many small cans to save time and a few dollars. You save more when you buy in bulk.

Brand

Pay extra attention to the brand you want to buy to ensure you get an authentic product. Some brands combine tung oil with additives and chemicals and sell it as pure Tung Oil.

If you want pure Tung Oil, ensure it states 100% Pure Tung oil on the product’s packaging. In other words, keep an eye on the product’s components.

Tung Oil Alternative Food safe Finishes

If you don’t want to use Tung oil for one reason, you could choose the following food-safe wood finishes.

Raw Linseed Oil

Raw linseed oil is a great wood finish and is a perfect alternative to pure Tung oil because it is non-toxic, eco-friendly, and versatile.

However, raw linseed oil takes longer to cure, making it slightly less desirable to some folks. It is one of the best natural finishes you can use for finishing wood. Read more here to learn about linseed oil food safety.

Mineral Oil

Mineral oil is odorless, tasteless, and takes much time to cure. Although it needs regular reapplication, it is perfectly food safe and a superb treatment as it enhances wood’s durability and beauty.

It soaks into the grain of the wood and coats the wood fibers with a water-repellent liquid. This prevents wood fibers from absorbing water, thereby preventing them from rot and decay.

Beeswax

Beeswax comes from honey bees, just as the name suggests, and has been used for centuries to treat food prep surfaces and other wood surfaces.

Although It is a perfect wood finish with no harsh chemicals or additives, it needs regular reapplication. It should be mixed with oil for a more straightforward application.
