Osmo Decking Oils (Wood Oils)
Overview
Osmo Decking Oil offers superior wood protection while enhancing the grain and character of your decking. Available in a variety of finishes, such as Osmo Decking Oil Grey and Osmo Black Decking Oil, this oil preserves timber against weathering and daily wear. Unlike surface-layering treatments, Osmo Decking Oil deeply penetrates the wood, delivering long-lasting protection without peeling or flaking.
For those who prefer a natural look, Osmo Clear Decking Oil is a standout choice, offering a transparent finish similar to teak oil. Additionally, the Osmo Decking Oil Colours range provides a wide selection, ensuring a perfect match for any outdoor setting.
Preparation
Proper preparation is crucial for achieving the best results with Osmo Decking Oil. Ensure your decking boards are clean, dry, and frost-free before application.
- Clean the surface: Remove dirt, debris, and any existing coatings. For previous oil-based finishes, use Osmo Decking Cleaner or lightly sand the surface. If your decking has become greyed or weathered, Osmo Wood Reviver Gel is ideal for restoring its natural colour before oiling.
- Strip old coatings: Sand or strip away old paints and varnishes to expose clean, bare wood.
- Protect against decay: Pre-treat the wood with Osmo WR Base Coat to guard against blue stain, mildew, and rot, ensuring a strong foundation for the oil.
Application
Osmo Decking Oil is perfect for decking, garden furniture, pergolas, and cladding. The proper application of Osmo Decking Oil ensures the best protection and aesthetic outcome.
- Test before full application: Apply a small amount to an inconspicuous area to check for compatibility.
- Determine oil requirements: Wood type and age affect absorption. Osmo Decking Oil is available in 750ml and 2.5-litre sizes to accommodate different project needs.
- Stir thoroughly: Mix the oil well before and during application for colour consistency.
- Apply evenly: Use a brush or decking applicator, working along the grain for even coverage. For best results, use the Osmo Floor Brush.
- Treat all sides: Apply oil to all surfaces, including the edges and ends, before installation to ensure complete protection.
- Wipe excess: Remove any excess oil to avoid pooling and uneven drying.
- Allow proper drying time: Let the Osmo Decking Oil dry for 10 to 12 hours before applying a second coat,
- Adjust colour intensity: For a lighter finish, use one coat of coloured oil, followed by a layer of Osmo Decking Oil Clear.
For areas prone to slipping, applying Osmo Anti-Slip Decking Oil over a base coat of coloured decking oil is recommended.
After Care
Maintaining your decking with Osmo Decking Oil is simple. Regular cleaning and occasional reapplication will preserve the protective finish and extend the wood’s lifespan.
- Routine cleaning: Use mild soap or Osmo Decking Cleaner.
- Reapplication: When signs of wear reappear, reapply a thin coat without the need for sanding.
- End grain protection: Use Osmo End Grain Sealing Wax to protect exposed wood ends.
- Enhancing adhesion: For new timber, a preliminary wipe with white spirit improves oil absorption.
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.
