Osmo UV Protection Oil provides a satin, protective finish for exterior wood. Self-priming, microporous and allows the wood to breathe. Reduces swelling and shrinkage. Water-repellent surface resists cracking, peeling, flaking and blistering. Use as a topcoat on wood previously colour treated. The oil has been developed to massively extend intervals between renovations.

All exterior woods grey into a patina colour over time. Osmo UV Protection Oil slows this greying process by (UV Factor) 12 times in comparison with untreated wood. This helps to keep the greying effect of UV rays at bay and protect your wood for longer. Active ingredients prevent mould, algae and fungal attack. Simply apply without sanding. Easy and seamless application. Finish stays workable while coating.

What is the main difference between 410 Clear and 420 Clear Extra?

Both products will significantly enhance the natural character of the wood. 410 Clear supports a healthy living environment without the use of biocides. The finish is designed to be safer for humans, plants and animals. A more eco-friendly choice. However, the 420 Extra Clear provides extra and more effective protection against algae, mildew and fungal attack.

Product Information
Safety Data Sheet 


Wood surface must be clean, dry and frost-free (moisture content max. 20%).

UV Protection Oil 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.

Fresh wood containing 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 Natural Oil Woodstain or Osmo Country Colour. Osmo UV Protection Oil should then be used as a top coat.

For renovations, clean old microporous wood finishes thoroughly. Clean and refresh already greyed or weathered wood at the same time 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. Trial apply the oil first for maximum confidence in the substrate you wish to apply to.

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 productinformation before use.


Apply thinly along the wood grain with Osmo Soft Tip Brush or Osmo Microfibre Roller and spread well.

Allow to dry for approx. 12 hours with good ventilation.

Then apply the second coat.


Oils enhance the natural tone of wood (permanent wet effect).

Depending on the degree of weathering, apply one coat of Osmo UV Protection Oil to the cleaned and intact finish after approx. 3–4 years.

For areas, which are highly exposed to weather, such as weatherboard, post caps or windowsills, please expect substantially shorter intervals between renovations. Vertical elements mounted onto horizontal wood should have at least a 15-degree angle. Sharp edges must be rounded (radius > 2 mm).

If the greying process has already begun, refresh the surface with Osmo Wood Reviver Power Gel and re-apply 2 coats of Osmo UV Protection Oil.

To achieve the UV protection factor 12, it is necessary to apply 2 coats of UV Protection Oil Extra. With only one coat on untreated wood, the life of the finish will be significantly shorter.

Due to the high oil content, UV Protection Oil has a light yellowing effect when used on white substrates. Therefore as a top coat on white finished areas, we recommend Osmo Natural Oil Woodstain 900 White.

Osmo UV Protection Oil contains biocides and therefore is only to be used on exterior areas. The added active ingredients delay or minimize the risk of algae and fungal attack.
