Application Tips
-
For ingredient-rich wood species (such as Cedar, Iroko, Teak, Mahogany, etc.) - please allow minimum of 12 weeks exposure in situ to the outside elements prior to application.
-
UV-Protection Oils are recommended only for vertically structured timber (drip angle min. 10º) 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 the drying times.
-
The high-energy UV rays of the sun destroy the lignin in wood: it greys. Up to now, only wood finishes with color pigments could possibly prevent this effect. With Osmo UV-Protection Oil, you have the possibility to protect your wood almost invisibly. UV-Protection Oil contains special ingredients that stall the greying effect by 12 times (UV factor 12). For reliable UV protection, the wood finish must be applied more generously than other wood stains from Osmo.
-
The recommended application amount is approx. 55 ml/m².
-
So that no micro-organisms, like mold, algae, or moss, can stick to a wood finish and cause unsightly discolorations, biocidal active ingredients for superficial film protection can be added. Biocidal ingredients are fine-tuned exactly so that a harmful effect for people can be largely eliminated.
-
Oak contains high acid content within its natural tannins and as a result, causes the timber to blacken during exposure to cold and moist environments - especially during the winter periods. More frequent care and maintenance are required, particularly in its first couple of years of exposure to the elements, to maintain its decorative appearance.
-
Many wood species contain water-soluble colored extractives which may leach out naturally when weathered.

Data Sheets
More Info
Preparation
Ensure that wood surfaces to be treated with Osmo UV Protection Oil are clean, dry and frost-free (moisture content max. 20%).
New Wood
- Surfaces should be sanded with a 120 grit abrasive and no finer
- New wood and especially hardwoods should be allowed to weather for approximately 6 weeks prior to oiling
- De-grease surfaces with methylated spirit or Osmo Brush Cleaner and Thinner (8000) before oiling
- Fill any holes or gaps with an exterior gap sealer
Please Note: Allowing the wood to weather, especially dense exotic hardwoods, enables the tight, dense grain of the timber to open up. This makes it easier to apply the oil and allows it to penetrate deeper in to the wood grain.
Old Wood
Clean old micro-porous finishes (wood oils) thoroughly
- Areas affected by mold, algae and moss must be cleaned and treated
- Old paints, lacquers and varnish like stains must be completely removed
- The color of timber that has turned grey / silver over time can be restored prior to oiling with Osmo Wood Reviver Gel (6609)
- Then treat as New Wood
Application
Always do a test area before starting any project to check suitability and compatibility. Follow the manufacturer’s instructions on the tin at all times.
- Stir thoroughly before and periodically during application
- Where possible treat all sides of the timber prior to installation
- Apply protection oil thinly along the wood grain with a natural bristle brush
- Work the oil into the surface of the wood grain
- Wipe of any excess with a clean, lint-free cloth
- Allow to fully dry
- Apply a second coat as above
Aftercare
Regular Cleaning
Oiled surfaces can be regularly cleaned with a suitable exterior spray cleaner that won’t strip away the waxes and oils.
Renovation
When renovation is required, ensure that surfaces are clean and dry.
- Lightly sand or use a stiff brush to remove surface dirt and debris
- Apply a thin maintenance coat of Osmo UV Protection Oil, taking care to work the oil in to the surface of the wood and wiping off any excess
- For wood that has become discoloured or is showing signs of mould, algae or moss, refer to the preparation and application sections above
