Product Information
Full details
The Osmo UV Protection Oil Tints in Larch (426) is designed for homeowners and DIY enthusiasts seeking to protect and enhance their exterior wood surfaces. Its key benefit is providing superior UV protection that delays greying by up to 12 times compared to bare wood, while also offering water repellency and protection against mould and algae. A minor caveat is that it requires two coats for optimal UV protection, and the specific colour tint may not suit all aesthetic preferences.

FAQs
How many coats of Osmo UV Protection Oil Extra are recommended for maximum UV protection?
For maximum protection against greying, two coats are recommended when used as a single-product application on vertical surfaces.
Can I apply this oil over existing paint or varnish?
This product is designed for bare wood or wood previously treated with oil-based finishes. It is not recommended for use over existing paint or varnish.
Do I need to sand the wood before applying a maintenance coat?
No, sanding is not necessary when applying a maintenance coat. Simply clean the surface and apply a thin, even coat of the product when signs of wear become visible.
What is the coverage rate of this product?
The coverage is approximately 18m² per litre with one coat.
How long does the finish typically last before needing a maintenance coat?
Depending on the exposure to weather and UV, a maintenance coat may be needed between 1 to 3 years. Look for signs of wear, such as reduced water repellency.
Can I use this product on interior wood?
This product is specifically formulated for exterior wood surfaces. For interior wood, Osmo offers different product lines.
What does 'wetted look' mean?
The 'wetted look' refers to the finish enhancing the natural grain and colour of the wood, making it appear as if it has just been wet, giving it a rich, deep appearance.
Troubleshooting
Wood still greys despite application
Ensure two full coats were applied, as this is necessary for the stated UV protection factor. Check if the product was applied thinly enough or if the wood was properly prepared.
Uneven colour or finish
Apply thinly and evenly with the grain. Avoid over-application or puddling. Ensure consistent application across the entire surface.
Product not drying properly
Ensure adequate ventilation and that the temperature is within the recommended range (typically above 5°C). Avoid applying too thickly, as this can hinder drying.
Water beading is not effective
This may indicate the finish has aged and requires a maintenance coat. Apply a new coat as per instructions.

Setup, Compatibility & Care Instructions
Preparation: Ensure the wood surface is clean, dry, and free from dust, dirt, and grease. If the wood is already coated, ensure the old coating is sound. For untreated wood, a single coat of Osmo UV-Protection-Oil Extra (clear) can be applied as a base coat for maximum protection, followed by two coats of the tinted UV-Protection-Oil.
Application: Apply thinly and evenly along the wood grain using an Osmo brush or roller. For optimal results, apply two thin coats. Allow 12 hours of drying time between coats. Recoat when signs of wear become visible, typically after 1-3 years depending on exposure, without sanding.
Compatibility: Suitable for all types of wood in outdoor areas, including decks, fences, pergolas, cladding, and garden furniture. It can be used as a single-product application or as a topcoat over existing colour-treated wood.
Care: Clean surfaces with a mild detergent solution and water. For more intensive cleaning or to restore the finish, apply a maintenance coat following the application instructions. Avoid abrasive cleaners.
