Osmo UV Protection Oil Extra is a breathable exterior wood finish designed to protect exterior timber from weathering, moisture and damaging UV rays whilst allowing the wood to retain its natural character. Formulated using a blend of natural sunflower, soybean and linseed oils, it penetrates deeply into the timber to provide long lasting protection whilst remaining water repellent and resistant to peeling, flaking and cracking.
Ideal for use on exterior timber including external doors, window frames, windowsills, carports, timber cladding, balcony elements, screens, smooth fences, pergolas, summer houses and garden furniture, Osmo UV Protection Oil Extra helps reduce the greying effect caused by UV exposure whilst nurturing the timber and leaving a durable, natural looking finish.
The "Extra" in Osmo UV Protection Oil Extra refers to the inclusion of biocides within the formulation, helping provide additional protection against algae, mould and fungal growth on exterior timber surfaces exposed to the elements. Designed primarily for smooth planed or sanded timber such as joinery, vertical cladding and furniture, coverage will be significantly reduced when used on rough sawn or featheredge timber. It is not recommended for flat, horizontal surfaces where standing water can collect, including decking, exterior floors, timber steps or flat window sills.
Colour Tips
Available in both clear and tinted finishes, choosing the right option depends on the desired appearance and level of protection. Clear finishes provide a subtle, natural appearance whilst still offering UV protection, whereas tinted finishes contain additional pigments that provide stronger UV resistance and can help extend maintenance intervals by offering greater protection against weathering and greying.
The clear version of this product can be used as a top coat for Osmo exterior coloured finishes, such as Osmo Natural Oil Woodstain and Osmo Country Colour. For a biocide-free alternative we recommend Osmo UV Protection Oil (410).
Ensure that all wood to be treated with Osmo UV Protection Oil Extra is clean, dry and frost-free (moisture content max. 20%). After periods of rain, allow the timber to dry for 2-3 days before application.
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 a suitable exterior wood filler
- Treat the wood with Osmo WR Base Coat (4001) if desired
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 for the oil to penetrate deeper in to the wood grain.
Old Wood
- Clean old microporous finishes (wood oils) thoroughly
- Areas affected by mould, algae and moss must be cleaned and treated
- Old paints, lacquers and varnish like stains must be completely removed
- The colour 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
Always do a test area before starting any project to assess product suitability and final finish. Follow the manufacturer's instructions on the tin at all times. Before opening the 5ml sample sachets, squeeze the packet several times to ensure that the oil and pigments inside are thoroughly mixed.
- Stir, without shaking, thoroughly before and periodically during application
- Where possible treat all sides of the timber including edges and ends prior to installation
- Thinly apply UV protection oil following the grain of the wood
- Allow to "soak in", then wipe off excess with a clean, lint-free cloth
- Allow to fully dry
- Apply a second coat as above
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 Extra, 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
