Description
Osmo UV Protection Oil Rapid 425 Extra Oak offers even more UV protection and enhances the natural characteristics of the wood. It 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 Rapid – 425 Extra Oak 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.
SURFACE PREPARATION
Wood surface must be clean, dry and frost-free (moisture content max. 20%). UV-Protection-Oil Tints is ready to use. Do not thin. Stir well using a flat stirring stick or spatula before use. Ideally, surfaces are sanded no finer than a P120 grit grade of sand paper. Sanding to finer grades will reduce required absorbency.
If possible, and if the wood is absorbent, please apply first coat to all sides before installation. Fresh wood containing natural wood ingredients /extractives (eg: Cedar, 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.
For renovation works, clean old microporous stains thoroughly – if necessary sand lightly. Clean and restore already greyed or weathered wood at the same time with Osmo Wood Reviver Power-Gel. 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.
METHOD OF APPLICATION
- With a Flat Brush or Microfibre Roller, apply thinly along the wood grain and spread well.
- Allow to dry for approx. 12 hours under good ventilation.
- Then apply the second coat.
- Alternatively the second coat can also be carried out with UV-Protection-Oil Extra Clear.
- When recoating colour treated surfaces, or for renovation works, one coat applied to the clean and dry surface is usually sufficient.
