1. Introduction
The Osmo UV-Protection Oil Extra 420 Clear is a clear, satin wood finish designed for exterior wood surfaces. This natural oil-based product offers advanced UV protection, helping to preserve the natural beauty of wood while preventing graying. Its microporous surface allows the wood to breathe, reducing swelling and shrinkage, and it is water repellent. This finish will not crack, peel, or flake, and when used as a topcoat on already color-treated wood, it significantly extends renovation intervals.
2. Safety Information
Always read the product label and safety data sheet before use. Ensure adequate ventilation during application and drying. Keep out of reach of children. Avoid contact with skin and eyes. In case of contact, rinse immediately with plenty of water. Do not ingest. Dispose of product and packaging responsibly according to local regulations.

4. Preparation
- Surface Condition: The wood surface must be clean, dry, and frost-free. Ensure the wood moisture content does not exceed 20%.
- Cleaning: Remove any dirt, dust, loose particles, or old flaking finishes. For previously oiled or stained wood, clean thoroughly. For new or untreated wood, a light sanding may be beneficial, followed by dust removal.
- Existing Finishes: Old paints and lacquers must be completely removed. Old open-pored stains or oils should be cleaned and lightly sanded.
- Wood Species: For exotic hardwoods, allow them to weather for at least 4 weeks before treatment to ensure proper absorption.
- Stirring: Stir the Osmo UV-Protection Oil Extra thoroughly before use.
5. Application
General Application Guidelines:
- Apply thinly and evenly along the wood grain.
- Use a good quality brush or roller.
- Ensure good ventilation during application and drying.
- Protect surrounding areas from splashes.
Step-by-Step Application:
- First Coat: Apply a thin, even coat of Osmo UV-Protection Oil Extra to the prepared, dry wood surface. Work along the wood grain.
- Drying Time: Allow the first coat to dry for approximately 10-12 hours under good ventilation. Lower temperatures and higher humidity will extend drying time.
- Second Coat: After the first coat is completely dry, apply a second thin, even coat.
- Final Drying: Allow the second coat to dry for another 10-12 hours. The surface should be fully cured and ready for use after 24-48 hours.
Important Note: For optimal results and longevity, always follow the manufacturer's instructions provided on the product packaging.
6. Maintenance
- Regular Cleaning: Clean the treated surface regularly with a damp cloth and a mild, pH-neutral cleaner. Avoid harsh chemicals or abrasive cleaners.
- Re-application: The frequency of re-application depends on the level of weathering and exposure. Typically, a maintenance coat is recommended every 3-5 years, or when the surface begins to show signs of wear or reduced water repellency.
- Spot Repair: Small areas of wear can be spot-repaired by cleaning the area and applying a thin coat of Osmo UV-Protection Oil Extra.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Uneven finish / Streaks | Too much product applied; uneven application; insufficient stirring. | Apply thinly and evenly. Ensure product is well-stirred. If dry, lightly sand and reapply a thin coat. |
| Slow drying time | High humidity; low temperature; poor ventilation; too much product applied. | Ensure good ventilation. Apply thinner coats. Allow more time for drying in adverse conditions. |
| Product not absorbing | Wood surface not clean or dry; previous finish not fully removed; wood moisture content too high. | Ensure surface is clean, dry, and free of old finishes. Check wood moisture content. |
