Description
Osmo UV Protection Oil Satin (410 Clear) enhances the natural characteristics of the wood and can be used on its own on vertical surfaces where it offers up to 12 times protection against UV degradation of the lignin in the wood. Osmo UV-Protection-Oil is based on natural vegetable oils. Natural oils penetrate deeply into the wood, keeping it elastic and healthy, and preventing it from drying and becoming brittle.
Osmo UV Protection Oil Satin (410 Clear) significantly prolongs the durability of wood treatments when applied on top – making renovation a much less frequent necessity. It protects against algae, mould and fungal attack, with a simple and straightforward application process outlined below.
Ideal Uses
Osmo UV-Protection-Oil Extra is ideal for all vertical wood surfaces in outdoor areas: doors, windows, window shutters (dimensionally stable elements), carports, timber cladding, balconies, fences, pergolas, and summer houses (dimensionally unstable elements). Also suitable for bamboo poles (e.g. in screens).
Preparation
Wood surface must be clean, dry and frost-free (moisture content max. 20%). Ideally, surfaces are sanded no finer than a P120 grit grade of sand paper. Sanding to finer grades will reduce required absorbency.
Osmo UV-Protection-Oil Exra is ready to use. Do not thin. Stir well using a flat stirring stick or spatula before use. If possible, and if the wood is an absorbent species, please apply the first coat to all sides before installation.
Fresh wood containing natural wood ingredients /extractives (eg: Cedar, Larch, Teak, Mahogany or Iroko) are often less absorbent and need to weather off first before applying the product. Please refer to website ‘Suitability’ section for more details. Weathering helps ingredient rich wood become more absorbent and the wood finish adheres optimally. Weathering is also required if ingredient rich wood has been freshly sanded or renovated.
A coloured base coat is recommended, e.g. Natural Oil Woodstain. Coloured base coats can improve UV protection.
For renovations, clean old microporous wood finishes thoroughly. De-grey any weathered bare wood with Osmo Wood Reviver Power-Gel before applying an Osmo exterior product.
Old paints and lacquers must be completely removed. As a general rule, wear a dust mask during sanding works. To maintain absorbency, avoid sanding surfaces finer than a P120 grit. Weather ingredient rich wood after sanding.
The finished surface is influenced by several factors, including the condition of the wood. Therefore, a trial application is always required, especially for unfamiliar surfaces.
Soft wood species like Pine or Spruce are more prone to blue stain, rot and insects. If desired, pre-treat these soft woods if possible on all sides with Osmo WR Base Coat.
Application
- Apply thinly along the wood grain with brush or roller and spread well.
- Allow to dry for approx. 12 hours. Cooler temperatures, higher humidity levels or over application will delay drying. Once dry, apply the second coat thinly.
- When recoating colour treated surfaces, or for renovation works, one coat applied to the clean and dry surface is usually sufficient.
We strongly recommend that you complete a small test area before commencing your job.
