Tung oil is an excellent finish for oak, providing a highly water-resistant, durable, and matte-to-satin finish that enhances the wood's natural grain. It is particularly favored because it cures into the wood fibers rather than forming a rigid plastic layer, which prevents cracking and makes spot repairs easy.
Best for: Hardwoods
Pure linseed oil is a traditional choice that soaks deep into the timber, nourishing it from within. It's great for hardwoods like oak or beech and gives a natural, slightly warm finish.
Tung Oil is easy to maintain. Re-application of one or two thin coats once a year will keep wood looking naturally 'fresh'. Damaged or scratched areas can easily be maintained by reapplication of Tung Oil. Tung Oil is suitable for use with exterior oak and teak.
Linseed oil is better suited for indoor applications, such as furniture and cabinetry, where it can provide a protective finish without the need for extreme durability. Application (harder to apply): In its raw form, due to it's pre-polymerization, its a very-thick oil and stickier than Pure Tung Oil.
You don't need to sand
Tung oil doesn't require it for adhesion, smoothness, clarity, or gloss (tung can be built to a gloss/semi-gloss too). That said, if your sheared surface isn't where you want it to be (or if you just prefer sanding), I recommend bringing the base surface to 600 grit or higher.
Pros & Cons of Tung Oil as a Wood Finish
It's all natural, non-toxic, and eco-friendly, and it doesn't yellow as much over time as common finishes like linseed oil, nitrocellulose lacquer, or varnishes like polyurethane. On the other hand, tung oil is expensive and susceptible to water rings, stains, and scratches.
Wait up to 45 minutes. If most of the oil (>80% of the surface) has absorbed into the wood within 45 minutes, repeat step 1 (Apply) and allow it to absorb again. Remove – Once the oil remains (puddles) on most (>80%) of the surface for more than 45 minutes, remove all excess oil by wiping with clean, dry rags.
No, Minwax Tung Oil Finish is not pure tung oil. It is a commercially blended product rather than a 100% natural extract.
The top-rated brands for 100% pure tung oil, favored for creating durable, eco-friendly, and food-safe finishes, are Real Milk Paint Company, Liberon, and WoodRiver. These products are highly recommended for their purity and ability to provide a deep-penetrating, matte finish that enhances the natural grain of the wood.
Tung Oil
It is clear, quick-drying, and penetrates the grain to enhance and protect the wood. It's one of the oldest and most popular wood finishes in the world and is derived from the seeds of the tung tree in Eastern Asia. Tung oil has become a staple among fine furniture craftsmen in the United States and beyond.
The best finish for oak depends on your desired look and usage. For a raw, natural appearance, choose a water-based polyurethane like General Finishes. For rich depth and character, use a penetrating Danish Oil Watco Danish Oil on Amazon. For superior, heavy-use durability, opt for a hardwax oil like Osmo Polyx-Oil.
Most woodworking projects require 3 to 5 coats of pure tung oil. However, the exact number depends on how much wear the piece will endure:
The "prettiest" wood depends on your desired finish, but Oak (Red and White), Ash, and Walnut are widely considered the easiest and most stunning woods to stain. Their open, porous grain structures absorb pigments evenly, avoiding the blotchiness seen in tighter, denser woods.
For new wood, Tung Oil should be thinned up to 50% with white spirit for the first two coats. This helps to aid absorption. These coats should be applied liberally and evenly. When applying with a cloth, use a circular or figure of eight pattern to work the oil into the wood.
Pro Tips for a Factory-Smooth Finish
Murphy® Oil Soap gets deep into grime to break up dirt particles and it's safe to use on wood products like cabinets. Next, gather another cloth or sponge. You may also want to use an old toothbrush to get into crevices.
Tung oil is an eco-friendly wood finish, but its main disadvantages include exceptionally long curing times, frequent maintenance requirements, and a lack of heavy-duty physical protection compared to synthetic finishes like polyurethane.
Whilst there are many 'old school' wood oils, the most commonly used are without a doubt Danish oil, Teak oil, Tung oil and to a lesser degree Linseed oil.
Bleach and Ammonia-Based Cleaners
Using these cleaners may discolor wood, erode the finish, and damage deeper layers of your floors. “Avoid harsh chemicals or abrasive cleaners, such as ammonia or bleach, which can strip the finish and damage the wood,” says Scott.
Linseed oil protects wood but can be prone to scratches and is less water-resistant than tung oil, making it better suited for indoor wood products. This is a more affordable option compared to other wood finishing oils.
Yes, you can apply polyurethane over tung oil. However, the tung oil must be completely cured before applying the polyurethane to prevent peeling or bubbling. The cure time depends on the specific product:
Proper Tung Oil Application and Surface Preparation
Oils, unlike clear surface coatings polyurethane, lacquer and shellac (from here in I will refer to them as surface coatings), should be finish sanded anywhere from 320 to 400 grit sandpaper.
For 100% pure, unadulterated tung oil, Walrus Oil Pure Tung Oil and Hope's 100% Pure Tung Oil are the top consumer choices. If you prefer a polymerized (faster-curing) formula, Sutherland Welles is the gold standard for durable, water-resistant, and food-safe wood finishes.
Tung oil definitely will deepen the hue of your wood. It's quite durable and food safe. It takes a long time to cure. For what you're looking for on this project, I'd recommend Danish Oil.
