Based on a solution of natural oils, Osmo UV Protection Oil can be used as a final one-coat finish on top of existing penetrating oils to prolong the restoration period, or as a standalone two-coat finish, prolonging the greying process by UV protection factor 12 when compared to unfinished timber. Osmo UV Protection Oil finishes to a satin, clear finish.
As a microporous finish, Osmo UV Protection Oil allows the timber to breathe, eliminating the chance of the finish cracking, peeling, blisters or flaking. The natural oils of Osmo UV Protection Oil penetrate deep into the wood, keeping it flexible and preventing the wood from drying.
Osmo UV Protection Oil is easy to apply, and maintain, with no sanding or priming required before or during application. Osmo UV Protection Oil can provide maintenance-free service of 3 to 4 years, depending on the exposure to direct sunlight and water.
Osmo UV Protection Oil is suitable for a range of products, including exterior vertical cladding and siding, doors, windows, garden furniture, fencing, screens, garden offices, summer houses, pergolas and more.
Osmo UV Protection Oil is free from biocides or preservatives, offering a safe finish for humans, plants and animals when dry.
Also available - UV Protection Oil Extra - preventative protection against algae, mould and fungal decay.
It is not necessary to sand the wood prior to application, however, if the boards show signs of mill glaze, lightly sand with 120 grit sandpaper.
Boards should be installed prior to application.
When using Osmo UV Protection Oil, the timber must be left to weather before application. The time left to weather will vary depending on the species of timber the oil is being applied to.
Please see the guide below for how long each species would have to be left to weather before applying the oil.
After the weathering period, it is generally recommended to de-grey the surface with a suitable product (eg Sansin Wood Cleaner or Owatrol Net-trol) and clean the surface from the extractive content before application. Always trial apply before use.
Osmo uses food-safe, natural ingredients for the basis of their wood finishes, waxes and pigments, including sunflower, soya, linseed and thistle oil, which is good for customers and wood alike.
Osmo products contain disaromatised white spirit to ensure finishes spread easily, removing the need for so-called "Green solvent" materials which can cause allergies.
Natural beauty of oils and waxes
Wood is a natural material, the cell structure, similar to our skin, can take on and release moisture, it breathes. To ensure that this exchange is not prevented we have created finishes especially suited to the character of the wood.
Osmo natural wood finishes are based on oils and waxes, the oil penetrates into the wood surface, protecting from deep within. The waxes form an elastic, micro-porous surface which protects the wood from external influences. The wood remains naturally beautiful, protected and durable.

UV-Protection Oil is recommended only for vertically structured timber (drip angle min 10°) to enable the rain to drip off rather than staying on the wood's surface for prolonged lengths of time.
Over application and/or low ventilation can increase drying times.
18 square metres per litre with one coat on smooth wood.
Coverage will vary depending on the type of wood, age and surface texture.
Ensure the surface is dry and clean from loose fibres, grease, dust and dirt.
Do not thin or dilute.
Stir well before use.
Do no sand prior to application.
Apply a thin and even layer, following the wood grain with a brush or roller, spreading well.
Allow good ventilation while drying - approximately 12 hours.

Recommended application amount is approx. 55ml/m².
Depending on the level of weathering, apply 1 coat of Osmo UV Protection Oil every 3 to 4 years and a clean and intact finish. Please note maintenance period can be shortened depending on climatic conditions and how exposed the material is to direct sunlight.
UV Protection Oil is unsuitable as a stand-alone finish for decking.
For ingredient-rich wood species (such as Cedar), please allow a minimum of 12 weeks exposure in situ to the outside elements prior to application.
Please be aware: the high oil content of Osmo UV Protection Oil shows a light-yellowing effect when used on white stained surfaces. In this instance, Natural Oil Woodstain White is recommended.
Treat any damage or cracks from everyday wear and tear in the finish immediately with two coats.
For full protection against timber weathering, cracking, swelling and shrinkage, use with Osmo End Grain Wax to seal the end grain of the wood.
Containing a high quantity of pigments and oils, Osmo wood finishes leave a stunning surface finish after just one or two coats, without the need for a primer or base coat.
This means you can achieve near to double the square meter coverage with just one tin compared to an ordinary finishing system.
When It comes to the Osmo paint range, no pre-priming is required, saving time and money.
