Product Information
Full details
This Osmo UV Protection Oil Extra, in Douglas Fir (427), is designed for professionals and DIY enthusiasts seeking to protect and enhance exterior wood surfaces. Its key benefit is significantly slowing the greying process caused by UV exposure, offering a durable, water-repellent finish. A minor caveat is that while it slows fading, some color change over time is natural, and for longer-lasting color, tinted versions are recommended. It features a microporous, oil-based formula that allows wood to breathe, easy application without primer, and resistance to common household spills.

FAQs
How long does Osmo UV Protection Oil Extra last outdoors?
The longevity depends on environmental factors, wood type, and exposure. Typically, a refresh coat is recommended every 1-2 years for optimal protection, which can be easily applied without sanding.
Can I use this oil on wooden decking?
While it offers UV protection, this specific product is best suited for vertical surfaces. For horizontal surfaces like decking, where water sits, Osmo Decking-Oils are more appropriate.
Do I need to prime the wood before applying?
No, Osmo UV Protection Oil Extra does not require a primer. It can be applied directly to clean, dry wood.
How do I clean application tools?
Clean brushes and cloths immediately after use with Osmo Brush Cleaner or a suitable solvent like turpentine substitute.
Can I apply a colored oil over the clear UV Protection Oil?
Yes, you can apply tinted UV Protection Oils or Natural Oil Wood Stains over existing, well-maintained coats of clear UV Protection Oil after cleaning.
What does 'mixed to order' mean for this product?
It means this specific variant (Douglas Fir - 427) is a lightly pigmented oil mixed specifically when you order it, ensuring freshness and precise formulation for vertical exterior wood applications.
Is this product suitable for children's toys?
Yes, Osmo UV Protection Oil is generally safe for wooden toys once fully dried and cured, as it's designed to be resistant to spills and wear. Always ensure the product has fully dried before use.
Troubleshooting
Wood still greying
UV Protection Oil slows greying but does not entirely prevent it. For maximum color retention, consider using one of the tinted UV Protection Oil versions or Osmo Natural Oil Wood Stain.
Uneven finish or brush marks
Ensure the oil was applied thinly and evenly. If the finish is wet, try to even it out immediately with a cloth. For dried marks, light sanding might be necessary before reapplication.
Surface is sticky or tacky after application
This usually indicates the oil was applied too thickly or did not dry properly due to poor ventilation or low temperatures. Ensure adequate drying time and good airflow. If still tacky, wipe with a cloth dampened with Osmo Brush Cleaner (or turpentine substitute) and allow to dry.
Water is not beading on the surface
The protective coating may have worn down over time. Reapply a thin coat of Osmo UV Protection Oil Extra to restore water repellency.

Setup, Compatibility & Care
Setup:
- Ensure the wood surface is clean, dry, and free from dust, dirt, or old finishes. If an old finish is present, it must be completely removed.
- Stir the oil thoroughly before and during application.
- Apply thinly and evenly with a brush (e.g., Osmo Flat Brush) or a lint-free cloth.
- Allow to dry thoroughly. Drying times depend on ventilation and temperature (typically 12-24 hours).
- For optimal protection, apply a second thin coat after the first has dried.
Compatibility:
- Ideal for all smooth and rough sawn domestic and exotic hardwoods and softwoods, especially for vertical surfaces outdoors.
- Suitable for use on garden furniture, cladding, fences, screens, pergolas, and trellises.
- Can be used on thermally modified wood.
- Not recommended for horizontal surfaces like decking or terraces where there is constant water exposure, as specific decking oils are better suited for these applications.
Care:
- Clean the surface with a damp cloth.
- For stubborn dirt, use a mild, soapy water solution and rinse thoroughly.
- To refresh the finish, apply one thin coat of Osmo UV Protection Oil Extra to any clean, dry area without sanding. This makes maintenance straightforward and avoids the need for complete refinishing.
