Oiling Your Deck: How Often Should You Do It?

Oiling your deck is an important part of keeping it looking its best and extending its life. It’s also a great way to protect the wood from moisture, sun damage, and pests. But how often should you oil your deck?

Benefits of Oiling Your Deck

When you oil your deck, you’re protecting it from water damage and helping to keep it looking good for longer. The oil acts as a barrier between the wood and any moisture that could cause rot or discolouration over time. Additionally, the oils help prevent UV rays from fading or warping the wood fibres in direct sunlight. Finally, some types of oils can even repel insects like termites which can be damaging to wooden structures over time.

How Often Should You Oil Your Deck?

How often you need to oil your deck depends on several factors, including climate conditions, where you live and what type of wood was used in construction. Generally speaking, if your area experiences extreme weather changes throughout the year, then every 3-4 months is recommended for optimal protection against wear-and-tear caused by rain or snowfall, as well as exposure to direct sunlight during summer months. If, however, there are more moderate climates with a little variation, then once per year may suffice depending on usage levels, too; i.e., decks used heavily will require more frequent maintenance than those rarely used at all.

Key Takeaway: When oiling your deck, it is important to consider the climate and usage levels. It is generally recommended to oil every 3-4 months in extreme climates and once a year in more moderate climates. For optimal protection, use oils that will repel insects and act as a barrier against water damage and UV rays.

When Is the Best Time to Oil Your Deck?

When it comes to oiling your deck, timing is everything. Knowing when to oil your deck will help ensure that you get the best results and extend the life of your outdoor space.

Best Time of Year

The best time of year to oil a wooden deck is in late spring or early summer when temperatures are warm but not too hot. This allows for the wood to absorb the oil and helps prevent cracking due to extreme weather conditions. Avoid doing this during periods of high humidity, as this can cause mildew growth on the wood surface.

Best Time of Day

It’s also important to consider what time of day you choose for applying an oil treatment onto your decking boards. The ideal time would be in the morning or evening hours when direct sunlight isn’t hitting them directly, as this could cause discolouration or warping from excessive heat exposure. If possible, try and pick a dry day with no rain forecasted so that you don’t have any issues with water diluting or washing away any product applied onto the surface before it has had enough time to properly soak into each board grain structure.

Weather Conditions

Finally, make sure that there aren’t any strong winds blowing around while you’re working on treating your decking boards – especially if using aerosol products such as varnish sprays which could end up getting blown all over other surfaces. Additionally, avoid attempting an oil treatment if there has been heavy rainfall recently, as moisture levels within each board may still be quite high and won’t allow for adequate absorption rates required by some oils or varnishes.

It’s important to oil your deck regularly to keep it looking great and prevent any damage from weathering. To make sure you’re doing it correctly, follow these DIY tips for oiling your deck.

Key Takeaway: When oiling a wooden deck, it is best to do so in late spring or early summer when temperatures are warm and not too hot. Avoid direct sunlight, strong winds, high humidity and recent heavy rainfall for optimal results.

DIY Tips for Oiling Your Deck

With a few simple steps, you can easily oil your own deck without having to hire a professional. Here are some tips for DIY-ers looking to get started:

preparing deck for oiling

Preparing Your Deck: Before applying any type of oil, it’s important to prepare the surface properly. Start by sweeping away any dirt or debris that has accumulated on the wood, and then use a pressure washer with a low setting to remove any stubborn stains or discolouration. If there are any cracks in the wood, fill them with epoxy filler before proceeding.

Applying Oil: Once your deck is prepped and ready for oiling, select an appropriate product for your specific type of wood (e.g., teak oil for teak decks). Apply the oil using either a brush or roller, depending on how large your area is; if you have intricate details like spindles or railings, use a brush, so you don’t miss anything. Make sure not to apply too much at once, as this can cause pooling which will take longer to dry out and may lead to mould growth down the line. Allow each coat plenty of time (at least 24 hours) before adding another layer – usually, two coats should be enough but check manufacturer instructions first, just in case.

Safety Precautions: As with all DIY projects involving chemicals, safety precautions should always be taken when working with oils, such as wearing gloves and protective eyewear while handling them as well as ensuring good ventilation during application (open windows/doors if possible). Additionally, make sure that all containers are stored safely away from children and pets after use until they have been completely emptied out – never leave open containers lying around.

Once you have completed these steps, your newly-oiled deck will last longer due to proper maintenance. Enjoy.

Key Takeaway: Oiling your deck is an important part of maintenance and can be done easily at home. Before applying oil, prepare the surface and select an appropriate product for the type of wood. When handling oils, take safety precautions, such as wearing gloves and protective eyewear, while ensuring good ventilation.


In conclusion, oiling your deck is an important part of maintaining it and keeping it looking great. How often you should oil your deck depends on the type of wood and how much wear and tear it gets. Generally speaking, a good rule of thumb is to oil your deck at least once every year or two. When you do this, make sure that you choose the right time – usually in spring or summer when there’s no rain forecasted for several days – so that the oil can penetrate deeply into the wood fibres. With these DIY tips for oiling your deck, you’ll be able to keep yours looking its best all year round!
