This product is not recommended for horizontal surfaces. Osmo UV-Protection-Oil is a satin-matte, clear finish for interior and exterior application with a great variety of uses. It is natural oil based and micro-porous, and does not crack, flake, peel or blister.

When used as a final finish after staining wood Osmo UV-Protection-Oil prolongs the renovation time significantly. However, when used as a complete finish by itself it blocks the greying process by UV-Protection factor 12 in comparison to untreated wood.

Osmo UV Protection Oil is recommended for all vertical exterior woods (dimensionally and non-dimensionally stable): doors, windows and windowsills, carports, timber cladding, balcony, screens & fences, pergolas and garden houses.

This product is not recommended for horizontal surfaces. Osmo recommends their Decking-Oil.

Directions for Use

Preparation

Wood surface must be clean, dry and frost-free (maximum moisture content 20%). Remove old varnishes. There should be a minimum 15 degree angle on architectural joinery on the horizontal e.g. windowsills. Sharp edges have to be rounded (corner radius > 2 mm).

Application

Osmo UV-Protection-Oil is ready to use. Please do not thin – stir well. Apply with stiff brush (Osmo Natural Bristle Brush) or a microfibre roller thinly and evenly along wood grain. Allow for good ventilation when used interiorly. When used as a complete finish apply second coat after drying. The finish is – among other things – influenced by the woods natural characteristics, therefore a trial application is required before finishing.

Drying time:

approx. 12 hours (dust dry in approx. 4 hours). Allow for good ventilation when used interiorly.

Advices:

Depending on the level of weathering apply 1 coat of Osmo UV-Protection-Oil after approx. 3 – 4 years on the cleaned and intact finish. In general, one has to take a shorter renovation time into account when surfaces are exposed to extreme weathering and surfaces where water cannot drain (horizontal surfaces). For timber species, which have water-soluble ingredients (e.g. Oak or Idigbo), and in some extreme locations the finish may require re-coating more regularly to maintain the unique protection qualities of this product. If, however, the greying process has already begun revive the surface with the Osmo Wood Reviver and re-apply with 2 coats of the Osmo UV-Protection-Oil.

FAQ

Can Osmo UV-Protection-Oil 420 be applied to a Western Red Cedar shingle siding?

The use of Osmo UV-Protection-Oil is highly recommended to protect cedar from UV rays and to prevent color changes due to wood aging. This oil offers UV protection with a factor of 12 for vertical surfaces (which means UV protection is 12 times higher than untreated wood).

For optimal results, it is recommended to apply two coats at an interval of 12 hours. One option is to apply a first coat of Osmo One Coat Only Stain to color the cedar, followed by one or two coats of UV Protective Oil. It is also possible to use a colored version of this UV oil. It is important to carefully read the product data sheet to understand the instructions for use and maintenance necessary over the years.
