Overview

Osmo Decking Oil is available in various shades, including Osmo Grey Decking Oil and Osmo Black Decking Oil, these oils offer both protection and aesthetic appeal. The Osmo Decking Oil Clear variant is a standout feature, providing a natural look reminiscent of teak oil. For specific preferences, the Osmo Decking Oil Colours range offers a diverse palette, including Osmo Decking Oil larch and Osmo 006 Bangkirai Decking Oil.

Osmo Decking Oil stands out in the market for its enduring quality, setting it apart from surface-layering products. These oils ensure a no-peel, no-flake finish, contrasting with other mainstream options. Osmo Decking Oil Teak 007 Clear is particularly noted for its effective protection against environmental elements, ensuring longevity and enhanced beauty of your timber decking.

Preparation

Proper decking preparation before applying Osmo Decking Oil is crucial for achieving the best results. Ensure your decking boards are clean, dry, and completely frost-free. This initial cleanliness is essential for the oil to adhere properly and penetrate effectively. 

Follow these steps for optimal preparation:

  • Deck Cleanliness: Ensure the decking boards are clean, dry, and frost-free.
  • Remove Old Coatings: Strip or sand off old paints, varnishes, and other finishes to expose clean, bare wood, ensuring a receptive surface for the new treatment.
  • Treat Old Stains: We recommend using Osmo Decking Cleaner to clean or lightly sand away previous oil-based treatments or stains, prepping the wood for a fresh application.
  • Protect Against Decay: To guard against blue stain, rot, and mildew, pre-treat the wood with Osmo WR Base Coat. This product is great for preparing your decking, as it provides a strong foundation for the oil and can help to extend your decking’s life.

Application

Suitable for various outdoor applications, Osmo Decking Oil is not only perfect for decking but also ideal for garden furniture, pergolas, and cladding. 

Applying Osmo Decking Oil correctly is key to achieving the best protection and aesthetic for your decking. It’s essential to start with a test application in a concealed area to ensure compatibility and satisfaction with the final appearance.

Follow these steps for optimal application:

  • Test Before Application: Do a patch test on a hidden section to confirm the product’s suitability for your decking.
  • Assess Oil Requirements: The oil quantity required varies depending on the wood's type and age. Osmo Decking Oil is available in a couple of size options - Osmo Decking Oil 750ml and Osmo Decking Oil Clear 2.5 litre.
  • Stir Thoroughly: Always stir the oil thoroughly before and during use to ensure uniformity, particularly with coloured oils.
  • Apply Evenly: Use a suitable brush or decking applicator to apply the oil evenly across the surface, working along the wood grain.
  • Use Suitable Tools: For more efficient applications, use tools like the Osmo Floor Brush or the Osmo Decking Brush Set, which helps distribute the oil evenly.
  • Treat All Surfaces: To provide comprehensive protection, ensure all sides of the decking boards, including edges and ends, are oiled before installation.
  • Wipe Excess: After application, promptly wipe off excess oil to prevent pooling and uneven spots.
  • Allow Drying Time: Allow the oil to dry for 10 to 12 hours before applying a second coat. Ensure good ventilation to allow for proper drying.
  • Adjust Colour Intensity: If a subtler colour is preferred, apply one coat of coloured oil followed by a clear or anti-slip decking oil as the final coat.

For areas prone to slip, using Osmo Anti-Slip Decking Oil over a base layer of coloured decking oil is recommended. For green growth contamination, Osmo Gard Clean is an effective treatment.

For ease, regardless of the size of your project, Osmo Decking Oil is available in a couple of size options - Osmo Decking Oil 750ml or Osmo Decking Oil Clear 2.5 Litre. You can select the one you need at the checkout.

After Care

Maintaining your decking with Osmo Decking Oil is straightforward. Regular cleaning and occasional reapplication will ensure the longevity of the finish. Osmo End Grain Sealing Wax is recommended for sealing end grains post-treatment, and for new timber, a preliminary cleanse with white spirit can enhance oil adhesion.

FAQs

How long does Osmo decking oil last?

Osmo Decking Oil’s longevity depends on the specific product used and the environmental conditions it is exposed to. Regular maintenance and the area’s weather conditions can affect how often reapplication is necessary.

Do you need two coats of Osmo decking oil?

Yes, two coats of Osmo Decking Oil are recommended for optimal protection and finish. This ensures even coverage and maximises the oil's durability on the wood surface.

Can you put too much Osmo decking oil on?

Applying too much Osmo Decking Oil can lead to issues such as a sticky or tacky finish. It’s important to apply the oil thinly and evenly to avoid oversaturation, which can also increase the likelihood of scratches and make the surface slippery in poor conditions.

Does Osmo decking oil make wood darker?

Osmo Decking Oil can enhance the natural colour of the wood, making it appear slightly richer or darker, especially if using tinted oils. However, the clear versions aim to maintain the wood’s natural appearance without significantly altering its colour.

Definitely needs 2 coats. First coat the wood just sucked it up. Second coat just protects it so well. You can see the rain just bounce off it.

Great value and amazingly quick turn around after order placed. Will be using each year when i repaint the decking.

First time I have used this decking oil I went for the grey which gives it a look of laminate.
Went on great but the proof will be who it looks in a year.
