Decking Oil: The Basics

Decking oil is a protective coating used to keep wooden decking looking good and safe from the elements. It’s an essential part of any outdoor space, providing protection against moisture, UV rays, dirt and other environmental factors that can damage the wood over time. Decking oil helps to preserve the look of your decking for years to come.

There are several types of decking oils available on the market today. The most common type is linseed oil-based decking oil which penetrates deep into the wood grain and provides a waterproof sealant while still allowing it to breathe naturally. This type of decking oil also adds colour to your timber as well as protects it from fading due to sunlight exposure. Other popular options include teak or cedar oils, which provide similar benefits but with more natural colours than linseed based products.

For those who want extra protection for their decks, there are also specialised water repellent coatings available such as Thompson’s Water Sealer or Sikkens Cetol DEK Finish, which offer superior resistance against moisture penetration while still allowing some breathability in order to prevent rot caused by trapped moisture inside the wood fibres. These products should be applied after applying regular linseed based oils in order for them to work effectively at keeping out water whilst preserving the natural beauty of your timber boards

Decking oil is a great way to protect your outdoor decking and keep it looking its best. Now that you know the basics, let’s take a look at how long it takes for decking oil to dry.

Key Takeaway: Decking oil is an essential part of any outdoor space, providing protection against moisture, UV rays and dirt. Common types include linseed oil-based decking oils, teak or cedar oils and water repellent coatings such as Thompson’s Water Sealer or Sikkens Cetol DEK Finish.

How Long Does Decking Oil Take to Dry?

Decking oil is a great way to protect and preserve your outdoor wood surfaces. It adds a beautiful finish that can last for years with proper maintenance. But how long does it take for decking oil to dry?

The answer depends on several factors, including the temperature, humidity levels, and type of oil used. Generally speaking, decking oils will take between 12-24 hours to fully dry in ideal conditions. However, if temperatures are too cold or humidity levels are high, then drying times may be longer than expected.

Temperature plays an important role in determining how quickly your decking oil dries out. If the temperature is below 10°C (50°F), then you should expect longer drying times as the colder air won’t allow the solvent in the oil to evaporate as quickly as it would at higher temperatures. On hot days however, when temperatures reach above 30°C (86°F), you should expect quicker drying times due to increased evaporation rates from warmer air molecules moving faster around your surface area, allowing more solvent particles to escape into the atmosphere faster than cooler air molecules do at lower temperatures resulting in shorter drying time frames overall.

Humidity also affects how fast your decking oil dries out – if there’s too much moisture in the air, then this will slow down evaporation rates which means slower drying times for your project. To speed up this process, try using a dehumidifier or fan near where you’re working so that excess moisture can be removed from the surrounding environment before applying any product onto the surface area and being treated with decking oils.

Finally, different types of oils have different properties which affect their rate of evaporation – some oils like linseed and tung tend to evaporate slower than other varieties, such as teak or walnut based ones which usually dry much quicker under normal circumstances but still depend heavily on environmental conditions mentioned earlier like temperature and humidity levels etcetera. So it is important to read instructions carefully before starting any project involving the application of these products onto wooden surfaces outdoors, especially during winter months when the weather might not always be ideal.

In conclusion, while there isn’t one definitive answer about how long it takes for decking oil to dry, understanding factors such as temperature and humidity can help give an idea of what kind of timeframe could be expected depending on the current environmental conditions. Therefore, keep these things in mind the next time you are planning any outdoor projects involving the use of these products.

It is important to understand how long decking oil takes to dry, as improper drying can cause damage. Therefore, it’s essential to know what happens if you don’t let the oil dry properly before continuing with your project.

Key Takeaway: The drying time for decking oil depends on temperature, humidity levels and type of oil used. Factors such as cold temperatures and high humidity can cause longer drying times. Use a dehumidifier or fan to speed up the process.

What Happens if You Don’t Let Decking Oil Dry Properly?

When it comes to decking oil, one of the most important steps is allowing it to dry properly. If you don’t let your decking oil dry correctly, you could be in for some serious trouble down the line.

Discolouration: One of the biggest issues that can arise from not letting your decking oil dry properly is discolouration. The wood may start to turn a yellowish or brownish colour due to moisture being trapped beneath the surface and unable to evaporate away. This will leave an unsightly stain on your beautiful wooden deck and can be difficult (if not impossible) to remove without sanding down the entire area and starting again with a fresh coating of oil.

Peeling: Another issue that can occur if you don’t allow your decking oil enough time to fully cure is peeling or flaking off of the wood surface. This happens when there’s too much moisture still present in the wood, which causes it to swell up and push against any existing coatings, resulting in them cracking or coming loose over time as they’re no longer able to adhere effectively anymore.

To avoid these problems occurring, make sure to follow all instructions carefully when applying any kind of outdoor treatment product, such as decking oils. This includes ensuring adequate ventilation during application and leaving plenty of time between coats for drying before adding more layers on top – usually at least 24 hours. Additionally, try using a water-based sealant instead if possible, as these tend to have shorter curing times than traditional oils, so are less likely to cause similar issues with prolonged exposure to wetness/moisture levels within their environment

Key Takeaway: Key takeaway: Make sure to allow adequate time for decking oil to dry properly in order to avoid discolouration, peeling and other issues. Tips include following instructions carefully, providing sufficient ventilation during the application, and leaving at least 24 hours between coats.


In conclusion, decking oil is an important part of keeping your outdoor space looking great and protecting it from the elements. Knowing how long does decking oil take to dry is essential for ensuring that you get the best results. If you don’t let the oil dry properly, you could end up with a patchy finish or even damage to your decking. So make sure to keep an eye on drying times and enjoy your beautiful new look!
