In addition to preserving the timber’s natural qualities, decking oil also enhances its aesthetic appeal by enriching the colour and grain pattern.
In selecting the most suitable decking oil, it’s essential to consider factors such as wood type, climate conditions, and desired finish. There are various types of oils available on the market, each with their own unique properties and benefits. By understanding these differences, homeowners can choose the ideal product to maintain the desired look and performance of their outdoor living space.
The application process of decking oil is relatively simple; however, following the manufacturer’s guidelines and taking the necessary precautions are vital for optimal results. It is crucial to prepare the surface correctly, remove any dirt or debris, and apply the oil uniformly using the appropriate tools. With proper care and maintenance, a deck treated with high-quality decking oil can last for years, providing beauty, safety, and enjoyment for homeowners and their guests.
Understanding Decking Oil
Types of Decking Oil
Decking oil is essential for maintaining the natural beauty and longevity of your outdoor deck. There are several types of oils available, including oil-based and water-based options. Oil-based products generally offer better penetration and longer-lasting protection, while water-based oils provide a more environmentally friendly option.
Additionally, decking oils come in a range of colours. The natural colour oils enhance and protect the wood’s original hue, while other colours provide a decorative finish and additional UV protection.
Choosing the Right Oil
When selecting a decking oil, consider the following factors:
- Type of wood: Different wood species have varying levels of natural oil and moisture content. Softwoods, such as pine, typically benefit from oil-based products, while hardwoods, like teak, can be compatible with water-based oils.
- Climate: Harsher climates with significant temperature fluctuations may require a heavy-duty oil that offers superior protection from the elements.
- UV resistance: Look for oils with added UV protection, especially if your deck is frequently exposed to sunlight.
- Maintenance frequency: Some oils require more frequent reapplication, so consider how much time and effort you’re willing to invest in ongoing maintenance.
Oil-Based vs Water-Based
Both oil-based and water-based decking oils have their own distinct pros and cons.
Oil-based decking oils generally provide the following benefits:
- Better penetration and adhesion to the wood surface
- Durable and long-lasting protection from moisture and UV rays
- Enhanced natural wood colours and grain patterns
However, they also have some drawbacks:
- Slower drying times
- Fumes and odours during application
- Higher levels of volatile organic compounds (VOCs)
Water-based decking oils, on the other hand, offer:
- Faster drying times
- Low odour and VOCs, making them more environmentally friendly
- Easier clean-up with soap and water
Despite these advantages, water-based oils may not provide the same level of protection and enhancement as oil-based options, particularly for softwood decks, so it’s important to weigh which advantages you value more.
Preparation for Application
When preparing to apply decking oil, it is essential that the deck is clean and free from dirt, algae and mildew. Before beginning any oiling, taking the proper steps to clean the deck will help ensure the final result is not only visually appealing but also lasts longer.
Cleaning the Deck
To start cleaning the deck, first, remove any loose dirt and debris from the surface. This can be done with a soft brush or broom. For wooden decking and wooden decks made of pine, fir, cedar, jarrah, spotted gum, merbau, or other materials, using a specialised deck cleaner is recommended.
The cleaning process should involve applying the deck cleaner to the entire surface of the deck with a brush or roller. Following the cleaner’s directions, let it sit for the indicated time, then scrub the surface with a stiff brush to remove stubborn dirt, algae, and mildew. Be cautious when scrubbing hardwood decking, as too much pressure can damage the surface.
For softwood decking, consider using a pressure washer to remove dirt and debris effectively. Be sure to adjust the pressure settings according to the specific wood type, e.g. natural oak, natural cedar, or natural pine. Exercise care when using a pressure washer on wooden decks, as excessive pressure can damage the wood fibres.
After the cleaning process is complete, it is essential to allow the deck to dry thoroughly. This may take between 24 to 48 hours, depending on the weather conditions. Ensuring the deck is fully dry before oiling will help the oil absorb better and provide better protection.
As you prepare your deck for oiling, remember that using a natural oil-based product will enhance the wood’s appearance and offer long-lasting protection without the need for paint or artificial coatings. By following these cleaning steps, your deck will be ready for the oil application, resulting in a stunning and well-maintained outdoor space.
Applying Decking Oil
Tools and Techniques
When applying decking oil, it is essential to use the right tools to ensure an even and durable finish. A quality brush or roller can be used for the application process. A decking pad can also be effective, as it covers larger surface areas and provides a smooth, even coat. Before beginning the application process, ensure the deck is clean, dry, and free from grease or other contaminants.
To begin, test the oil on a small, inconspicuous area of your decking to ensure you are satisfied with the colour and finish. Decking oil offers penetrating protection, which means it sinks into the wood rather than forming a film on top. This provides effective protection from UV rays and weathering, while also maintaining the natural appearance of the wood.
Number of Coats
It is generally recommended to apply at least two coats of decking oil for optimum results. The first coat should be allowed to penetrate and dry thoroughly, which may take between 24 and 48 hours, depending on weather conditions and the specific oil used. You should always refer to the manufacturer’s guidelines for the recommended drying time.
Once the first coat is dry, assess the coverage and finish. If the oil has penetrated well and provided the desired colour and protection, a second coat may not be necessary. However, for untreated or heavily weathered decking, a second coat can offer increased protection and durability.
Applying multiple coats of decking oil can result in a longer-lasting finish, ultimately reducing the need for frequent maintenance. Regular maintenance, including topping up any areas that show signs of wear, will help to keep the deck looking its best and prolong the life of the oil finish.
Remember, it is important to follow the specific guidelines provided by the decking oil manufacturer to achieve the best results and avoid any potential issues with drying or protection.
Durability and Protection
Resisting Weather and Wear
Decking oil provides protection for wooden decking from the various elements, such as sun, rain, and temperature fluctuations. Its primary purpose is to protect the wood from moisture, which can cause warping, splitting, and the development of mould. Moreover, it offers durability and prevents the wood from gradually greying, fading, and succumbing to wear.
Certain premium decking oils are specially formulated to provide added protection against the sun’s harmful rays, which can damage the wood’s structure and lead to cracks. These oils often contain pigments that resist the sun’s UV rays and help to maintain the wood’s natural appearance.
Decking oil can further protect the base from weathering by sealing the wood’s surface. This helps in preventing dirt, dust, and other stains from penetrating the wood’s fibres. Some decking oils also contain mould inhibitors, which are helpful in preventing mould growth.
Reapplication Frequency
The frequency of reapplying decking oil depends on several factors, including the type of oil used, the climate, and the level of wear on the deck. Generally, oil-based stains and sealers perform better in terms of durability and protection. They are more resistant to moisture and wear, and typically require less frequent reapplication compared to water-based stains or decking cleaners.
Most decking oils should be reapplied every 1 to 2 years, depending on the specific product and its recommendations. However, some heavy-duty products may extend their protection for up to 5 years. When reapplication is necessary, it is important to thoroughly prepare the deck’s surface first by cleaning it and removing any mould, dust, or patches.
In high traffic areas or decks prone to excessive moisture and sun exposure, touch-ups may be needed in between full reapplications. Regular checks will help determine this need and maintain your deck’s lasting protection from wear and the elements.
Remember, keeping the deck well-maintained with the proper use of decking oil will preserve the appearance of your wooden decking, and ensure protection from the pressure of weather and wear.
