Wood surface must be clean, dry and frost-free (moisture content max. 20%). Osmo UV Protection Oil Extra (420 Clear) is ready to use, please do not thin. Stir well before use. Clean old microporous stains thoroughly. Old paints and lacquers must be completely removed. As a general rule, wear a dust mask during sanding works. Do not sand smooth surfaces finer than P120. If possible, please apply base coat to all sides before installation. Fresh wood, containing natural wood extractives and especially hard wood needs to weather off (for approximately 6 weeks) after installation. Thereby the wood becomes absorbent and the wood finish adheres optimally.
A base coat with a coloured finish is recommended, e.g. Osmo One Coat Only HS Plus, Osmo Natural Oil Woodstain or Osmo Country Colour. For renovations, clean old microporous wood finishes thoroughly. Already greyed or weathered wood should be refreshed and cleaned with Osmo Wood Reviver Power-Gel. The finished surface is, among other things, influenced by the wood‘s natural characteristics. Therefore, a trial application is always required, especially for unfamiliar surfaces. If additional protection against blue stain, rot and insects is desired, pre-treat the wood if possible on all sides with Osmo WR Base Coat. Use biocides safely. Always read label and product information before use.
- As self-priming finish, it prevents the greying process on vertical surfaces with a UV protection factor 12 in comparison to untreated wood when two coats are applied
- For ingredient rich wood species (such as Cedar, Iroko, Teak, Mahogany etc.) - please allow minimum 12 weeks exposure in situ to the outside elements prior to application.
- Osmo UV Protection Oil Extra (420 Clear) is recommended only for vertically structured timber (drip angle min. 10º) to enable the rain to drip off rather than stay on the wood's surface for prolonged lengths of time.
- Over application and/or low ventilation can increase the drying times.
- The high-energy UV rays of the sun destroy the lignin in wood: it greys. Up to now, only wood finishes with colour pigments could possibly prevent this effect. With Osmo UV Protection Oil Extra (420 Clear), you have the possibility to protect your wood almost invisibly. Osmo UV Protection Oil (410 Clear) contains special ingredients that stall the greying effect by 12 times (UV factor 12). For a reliable UV protection, the wood finish must be applied more generously than other wood stains from Osmo.
- Recommended application amount is approx. 55 ml per m2.
- Oak contains a high acid content within its natural tannins and as a result causes the timber to blacken during exposure to cold and moist environments - especially during the winter periods. More frequent care and maintenance is required, particularly in its first couple of years of exposure to the elements, to maintain its decorative appearance.
