Natural wood oil protection is one of woodworking’s least talked about subjects…

But boy, does it matter.

Aesthetics are important. Grain patterns, stains, and timber selection matter more than ever in the age of stock footage websites and factory mills.

But wood can be stained any colour. It can’t truly be protected without a proper finish.

No matter how good the lumber source or design template is, if the wood isn’t properly finished it will fail. Every single time.

The good news? A natural wood finish choice doesn’t have to be complicated.

Look for an oil that will:

Soak into the grain deeply
Lock out moisture and UV rays
Bring out wood’s natural colour
Provide years of protection with minimal maintenance

The bad news? There are a lot of so-called “natural” finishes out there that aren’t.

Here’s what’s covered:

Why wood protection matters
What makes a wood finish “natural”
The best natural wood finishes to know
How to apply natural wood protection
Which oil finish works best for different projects

Let’s dive in.

Why Natural Wood Oil Protection is Important

Wood moves.

Even when kept indoors at stable temperatures, wood expands, contracts, and reacts to humidity.

The hygroscopic nature of timber is why finishing it matters in the first place.

The global wood preservatives market was valued at $2.90 billion in 2024. Protecting wood from rot, insects, fungus, moisture, and sunlight isn’t just recommended… it’s a booming industry.

A good natural wood protection oil adds:

A robust moisture barrier
Defense against UV damage
Prevention of mould and insect damage
Stability against scratches and day-to-day use

Skip the finish, and none of those become possible.

Wood is left to withstand threats alone. Suddenly hardwood floors start to fade. Rot starts to take hold. Erosion occurs as the wood fibres dry out.

Time and time again, wood protectors triumph over bare wood longevity tests.

They’re a wood’s first, and most important, line of defense against the elements.

What Qualifies As A “Natural” Finish

Tung oil. Linseed oil. Natural-ish Danish oil.

Not all finishes considered “natural” by manufacturers are actually natural.

Believe it or not, some brands use synthetic solvents to speed up drying times. Others add VOCs and other chemicals to boost longevity and “feel”.

Carefully read labels.

When looking for the best natural wood oils, ensure the finish:

Comes from a plant source like tung trees, flax seeds, or other edible oils
Is free from VOCs
Is food-safe after fully curing
Soaks into the grain without forming a surface film

Does the finish meet those criteria? Then it’s a natural protector that works with wood’s natural qualities… not against them.

Remember, certain natural wood finishes like tung oil harden at a molecular level inside wood fibre. Others are “film-forming” like polyurethane, and don’t soak into wood nearly as well.

How To Choose The Right Natural Finish

By far the best natural wood finish on the market is tung oil.

Made from pressed tung tree seeds, tung oil has been protecting wood for centuries around the world. It was once the protection of choice for wooden ships sailing out of Chinese ports.

The problem is, not all tung oil is created equal. Ready-made oil blends like RMP Finishes tung oil are far superior to ones found at the hardware store.

Why?

It’s pure. Hardware store tung oil typically contains synthetics to help it dry faster. While that isn’t necessarily bad, RMP’s tung oil formula penetrates up to 5mm into wood fibre and resists water better than any other pure wood oil on the market.

Is tung oil perfect?

Not quite. It takes a few days to fully cure, and isn’t completely food safe by itself (food safe when mixed with mineral oil).

That’s where number 2 on the list comes in handy.

Linseed Oil

Linseed oil is extracted from the humble flaxseed. Like tung oil, it can be bought in raw and “boiled” varieties.

Because boiled linseed oil is quicker to dry (drying agents have been added), most woodworkers don’t consider it natural.

That doesn’t mean it shouldn’t be used. If linseed oil is the preference, boiled linseed oil will do the job just fine.

Go with raw if there’s time. It’s the purest form and gives wood a lovely amber hue that highlights rustic details.

Danish Oil

Technically Danish oil isn’t natural at all.

It’s typically a combination of tung oil and linseed oil plus a varnish or polymer to speed up drying time. That means Danish oil will dry faster than raw tung oil.

Choose it when pressed for time. Don’t expect the same level of penetration and wood feel that pure oils provide.

Applying Natural Wood Protection

Here’s the secret nobody tells about applying oil wood finishes…

Don’t skimp on prep or application.

For wood protection oil to do its job, wood needs to be prepped professionally every time. Here’s how:

Sand surface with 80 grit sandpaper, and work up to 220 grit
Wipe clean with a lint-free rag — all dust removed
Apply first coat liberally with a brush, pad, or cloth
Leave to penetrate for 15–30 minutes
Wipe off excess oil with a clean cloth — don’t let any sit on the surface
Wait 24 hours for oil to cure
Apply next coat, repeating for 2–4 coats total

How Many Coats Should Be Applied?

This will vary from wood to wood. Softwoods require more coats than hardwoods. Porous wood requires more coats than dense timber.

The rule of thumb? Don’t leave oil sitting on top of wood. Always wipe off excess after oiling. That means no puddles or saturated spots.

Each coat should soak into the wood within 30 minutes.

Repeat for as many coats as needed.

Recommended Oil Finish For The Job

All wood oil protects wooden surfaces from above. But wood expands and contracts below the surface too.

That’s why a project’s location matters when choosing a wood oil finish.

Here are the best uses for natural wood oil finishes:

Indoor furniture — tung oil, linseed oil
Indoor floors — tung oil or raw linseed oil
Outdoor decks — tung oil
Outdoor furniture — tung oil
Cutting boards — pure tung oil*
Kitchen surfaces — pure tung oil*
Antique wood restoration — raw linseed oil

*Food safe after curing and mixed with food-safe mineral oil.

Expect Natural Wood Oil Product Market Growth To Increase

The natural wood oil debate isn’t going anywhere.

The global sustainable wood products market is estimated at $150 billion in 2025. More and more people are demanding sustainable, healthy products.

Sure, there are oils with VOCs and synthetics that can help boost a project’s durability and longevity.

But there’s something to be said about preserving wood the way nature intended.

How To Sum Up Wood Finishing

The wood is selected. The natural wood oil finish is chosen. Now it’s time to make it beautiful.

A few things to keep in mind:

Be sure to use 100% natural products. Lots of “natural” finishes contain synthetic drying agents.
Don’t forget about the wood type. Softwoods need more coats than hardwoods. Heavy use areas need more coats.
When in doubt, err on the side of more coats.
Thin, even coats. Never leave puddles of oil on the wood surface.
Clean oil immediately penetrates wood and doesn’t stay wet. If puddles appear, wipe them off immediately.
Reapply as needed. Wood protection doesn’t just happen once. Renew protection annually, or whenever the wood stops beading water.

Natural wood oiling isn’t difficult. But taking shortcuts means sacrificing the benefits of a pure tung oil wood finish.

Protect Your Wood The Right Way

From picking a raw tung oil wood finish to properly prepping a wood surface, proper care ensures wood stays protected for years to come.
