Osmo Uv Protection Oil Extra - Clear Matt - 2.5 L

The 'Extra' version contains a higher concentration of active ingredients for enhanced protection against mould, algae, and fungal attack, offering superior durability compared to the standard version.

Osmo generally does not recommend this product for decking or horizontal surfaces that experience heavy foot traffic due to wear and tear. For decking, consider products like Osmo Decking-Oil.

Reapplication frequency depends on the exposure to weather. Typically, a maintenance coat is recommended every 2-3 years, or when signs of wear appear. Applying one coat is usually sufficient for maintenance.

For the best UV protection and to significantly block the greying process, a colored base coat like Osmo Natural Oil Woodstain or Osmo Country Colour is highly recommended. This clear finish alone provides UV protection, but the colored base enhances it.

Drying time is typically 12-24 hours, but this can vary based on ambient temperature, humidity, and ventilation. Ensure adequate drying between coats.

Clean the surface with a damp cloth and mild soap. Avoid using harsh chemicals or abrasive cleaning tools that could damage the finish.

This product is specifically designed for exterior wood applications. For interior wood, Osmo offers a range of interior finishes suitable for different wood types and uses.

This can occur if the product was applied too thickly or not evenly. Ensure the product is applied thinly and evenly along the wood grain. Remove excess product if it has not dried.

Check ventilation and ambient temperature. Ensure the surface was clean and dry before application. Avoid applying in very humid or cold conditions. Ensure no incompatible substances were present on the wood.

Ensure the surface was properly prepared. Old finishes may need to be removed or scuff-sanded if they are not porous or if they are flaking. Ensure compatibility with previous finishes.

Ensure two coats of the UV Protection Oil Extra were applied, or that a sufficient UV-protective base coat was used. The UV protection factor of 12 is relative to untreated wood; some greying may still occur over very long periods or in extreme conditions.
