Danish Oil Advantages and Disadvantages (Explained!)

In the world of wood oil finishes, Danish oil ranks high but before you use this wood oil finish, it’s important to know the pros and cons of Danish oil.

The main advantage of Danish oil is that the wood oil finish is non-toxic and considered to be food-safe meaning that you can use it on any wooden surface in your home without worrying about food poisoning or toxins.

Danish oil is also waterproof as the finish hardens to form a waterproof layer on the wood – this protects the wood from water damage, rotting, and decaying.

The disadvantage of Danish oil is that you can only apply the wood oil on bare wood. Also, Danish oil is not very durable – the finish can’t withstand scratches, dents, or foot traffic.

This post reveals more advantages and disadvantages of Danish oil including the best uses for the wood oil. Let’s dive in.

What is Danish Oil?

Danish oil is a hybrid wood oil finish that is made by combining natural wood oils and a solvent. There is no specific formula or makeup for Danish oil as the ingredients in the wood oil ranges from brand to manufacturer. However, most Danish oil wood finishes contain Linseed oil, Tung oil, and mineral spirits.

Danish oil is usually applied by using rags and clothes due to the thick nature of the wood oil. The finish is usually wiped on wood and can only be used on bare wood. When Danish oil is applied, the wood oil finish soaks in the wood fibers and forms a shiny layer on the wood that gives a glossy and bright finish.

Next, let’s check out the advantages of Danish oil.

Danish Oil Advantages

Danish Oil Advantages

Here are the perks and benefits that you’ll enjoy before, during, and after applying Danish oil to your wood:

1. Dries Fast

One main advantage of Danish oil is that it dries quickly. When compared to other wood oil finishes, Danish oil has a quick dry time.

On average, Danish oil will dry fully in less than 8 hours after its application. Other wood oil finishes like Tung oil take at least 24 hours to fully dry and others take days before drying.

You should know that though Danish oil dries quickly, the dry time of the wood oil finish is also subject to room temperature, weather, and humidity.

2. Waterproof

Perhaps one of the main reasons why people choose Danish oil is because of its waterproofing qualities. When Danish oil is applied, the oil deposits in the finish react to the oxygen in the atmosphere to solidify and form a waterproof layer on the wood. This layer protects the wood from water damage, rotting, and decaying.

3. Danish Oil is Non-toxic and Food Safe

Danish oil is one of the few wood finishes that is considered to be non-toxic and food safe. This means that the wood finish contains no toxins and as such can be used in kitchens and dining areas with no threat of food poisoning. You can even use Danish oil on baby furniture.

The reason Danish oil is non-toxic is that the finish is gotten from natural oils and not synthetic oils. Also, Danish oil has no chemicals, resins, or the likes that can produce fumes or toxins during and after application.

4. Flexible

The finish that you get after Danish oil application is usually flexible or elastic. The elasticity of the finish makes it cope better with temperature changes in the environment.

It also means that the Danish oil finish can cope with the contraction and expansion of the wood during temperature changes. This limits the possibility of cracks and lines on your Danish oil finish.

4. Danish Oil Can Be Used as a Primer

Unlike other wood oil finishes that can’t accept a top coat, Danish oil can. You can even use Danish oil as a waterproof primer coating before covering it with a top coat or sealant.

However, you should know that you need to sand the Danish oil lightly before applying a top coat. Also, you should only use an oil-based finish on the Danish oil topcoat as only oil-based top coats will stay on the Danish oil coating.

6. Doesn’t Yellow

Another advantage of using Danish oil is that the finish doesn’t yellow like other oil-based finishes. Danish oil retains its clear finish meaning that the wood grain will be revealed through the Danish oil finish. Danish oil also helps to enhance the sheen of the wood.

7. Some Brands of Danish Oil Offer Heat Resistance

Heat can cause discoloration and burn marks on wood but Danish oil helps to prevent this. The heat resistance of the Danish oil finish is due to the presence of Tung oil in the finish.

Tung oil can remain stable up to 350 degrees Fahrenheit and the presence of this wood oil in Danish oil also gives the Danish oil improved heat resistance. You should know that heat resistance is not the same as fire resistance.

8. Sticks Well to Wood

Another advantage that you’ll enjoy from having Danish oil on your wood is that the wood oil finish sticks well to wood. Danish oil when applied soaks into the wood and bonds to the wood fibers creating improved adhesion between the Danish oil coating and the wood surface.

9. Affordable

The price tag of Danish oil is usually less than $30 unless you want to purchase the large containers which still cost less than $80. Most wood oils cost more than Danish oil. Tung oil for instance costs at least 50% more than Danish oil.

Next, let’s check out the disadvantages of Danish oil on wood.

Danish Oil Disadvantages

Danish Oil Disadvantages

Here are a few reasons people don’t choose Danish oil:

1. Danish Oil Application is Time-consuming

The first factor is that Danish oil application can be time-consuming and this is common with wood oil finishes. The texture of Danish oil means that you need more coats of the wood oil for proper coverage on wood and if you’ll be applying multiple coats, you need to allow each coat to dry before applying the next.

Danish oil takes about 8 hours to dry. Though this is a quick dry time for a wood oil finish, it still doesn’t change the fact that you have to wait 8 hours between each coat that you apply. So if you are applying 4 coats of Danish oil, that means you’ll need more than 24 hours (or a day) to finish your application.

2. Not Durable

Another disadvantage of Danish oil is that the finish is not durable. Danish oil due to the thin texture of the finish wears off quickly, especially on busy wood surfaces.

Danish oil doesn’t last long on wood and on a busy wooden surface, the Danish oil finish will last 2 years at best before you need to reapply the finish. Since Danish oil is not durable, you’ll need to touch up the finish frequently which can lead to more work in the long run.

3. Poor Wood Protection

A similar advantage to the low durability of Danish oil is its poor wood protection. Since Danish oil is thin, the finish can not withstand scratches, dents, wear, and tear – this means that the finish can’t protect your wood from these factors either.

The poor level of wood protection is why Danish oil is not commonly used on busy surfaces like floors and countertops. If wood protection is what you want, you’ll need a stronger finish than Danish oil.

4. Danish Oil Only Goes on Bare Wood

This is another major limitation to Danish oil. Since Danish oil needs to penetrate and be absorbed in the wood fibers, you can’t use the wood oil finish on an already stained or finished wood. This is because the existing stain or finish on the wood will prevent the Danish oil from being absorbed fully into the wood fibers.

This will lead to poor adhesion between the Danish oil coating and the wood. If you want to apply Danish oil on an already stained wood, you’ll have to strip the existing finish first.

5. Tough to Clean and Maintain

For all the perks of the Danish oil finish, the finish is usually difficult to maintain. The high maintenance needs of Danish oil are down to the fact that the finish is not durable or strong.

As such, you’ll need to regularly wipe, clean, dissolve, and maintain the finish. You’ll also need to touch up the finish every now and then by sanding and applying new coats whenever the existing one wears off.

6. Flammable

The flammability of Danish oil is due to the presence of mineral spirits (a petroleum-based solvent) in the Danish oil formula. The presence of mineral spirits can cause the Danish oil finish to ignite and catch fire if exposed to a naked flame.

Tips on How To Apply Danish Oil

Here are expert tips to follow when applying Danish oil:

  1. Always sand the wood with fine sandpaper before applying Danish oil. If the wood is very rough or patchy, start sanding with medium-grit sandpaper and finish off with 220-grit
  2. Strip or remove existing finishes on the wood before applying Danish oil
  3. Apply the first coat of Danish oil using a clean cloth and leave to dry for at least 6 hours before applying the next coat
  4. Sand each coat of Danish oil with 400-grit sandpaper before applying the next coat
  5. Always remove sanded dust using a vacuum before applying a new coat of Danish oil – if you don’t remove sanded dust, the Danish oil will be riddled with bumps
  6. Don’t use the Danish oil finish after application – leave for at least 24 hours to cure before use.
  7. Always follow the manufacturer’s instructions or user’s guide while applying Danish oil.

How Long Does Danish Oil Last?

Danish oil doesn’t last very long on wood because the finish is easily worn off by friction and constant use. On average, Danish oil lasts between a year and 2 years on busy wood surfaces like floors.

If the wood isn’t used frequently, Danish oil can last about 3 years before you’ll need a touch-up. However, if you touch up the finish frequently, the Danish oil will last longer.

How Many Coats Of Danish Oil Do You Need?

You need at least 2-3 coats of Danish oil for proper coverage on wood. This is because Danish oil has a thin texture and as such, you’ll need more coats for proper coverage. On busy surfaces, you’ll need more coats of Danish oil, usually at least 4 coats.

Do You Need To Seal Danish Oil?

You don’t need to seal Danish oil but you can if you want the finish to last longer. However, you should know that only oil-based paints and sealants can be used to seal Danish oil due to the high volume of oils in Danish wood oil. Also, ensure to sand before sealing Danish oil to allow the new sealant to adhere properly to the existing Danish oil finish.

Should You Sand Between Coats Of Danish Oil?

You need to sand between coats of Danish oil because Danish oil doesn’t smoothen wood. When dry, Danish oil reveals a few pimples and bumps that should be sanded off before applying the next coat.

You should also know that the 6-hour dry time of each Danish oil coat allows dust nibs to settle on the coat. So before applying the next coat, you need to sand these dust nibs off with very fine sandpaper. The recommended grit is 400-grit sandpaper.

Final Words

In summary, Danish oil has its pros and cons and before you decide on going for the finish, you should consider the factors above to know if Danish oil is your best bet or not.

Remember that the finish doesn’t offer good wood protection and is not durable – so you’ll need to touch up the finish frequently. However, Danish oil offers good waterproofing and is non-toxic making it ideal for just about any surface in the home.
