Osmo UV Protection Oil Extra (420 Clear) provides a microporous surface allows the wood to breathe and reduces swelling and shrinkage. Osmo UV Protection Oil 420 provides a surface coating rather than a oil finish. If you require an oil finish, please look at the Osmo UV Protection Oil 410.
Water-repellent, does not crack, peel or flake. Simply apply without sanding. Easy and seamless application. Finish stays workable while coating. As top coat on already coloured treated wood,Osmo UV Protection Oil Extra (420 Clear) extends intervals between renovations significantly. 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.
Osmo UV Protection Oil Extra (420 Clear) is ideal for all exterior vertical wood surfaces: doors, windows, window shutters (dimensionally stable elements), carports, timber cladding, balconies, fences, pergolas, and summer houses (dimensionally unstable elements).
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.
