Designed for vertical exterior surfaces such as timber cladding, fencing, doors and windows. You can use osmo’s uv protection oil on horizontal surfaces such as decking or garden furniture when used as a top coat only over a coloured finish such as Osmo One Coat Only, Natural Oil Woodstain or Decking Oils.
- For new oily or exotic wood species, please allow approx. 3 months exposure to the outside elements prior to application.
- UV-Protection Oils can only be used as a top coat on flat or horizontal surfaces (drip angle less than 10º) as the rain/water will need to run off the wood rather than absorb into UV-inhibitors within the finish.
- Over application and/or low ventilation can increase the drying times.
Wood surface must be clean, dry and frost-free (moisture content max. 20%).
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.
