OSMO UV-Protection-Oil-EXTRA, 420, Clear, Satin, with Film Protection
CLEAR NATURAL OIL-BASED UV PROTECTIVE FINISH
Difference beween Osmo UV-Protection-Oil 410 and Osmo UV-Protection-Oil-Extra 420:
While both products provide a clear, satin finish with very low V.O.C content and are made from a unique combination of natural oils and waxes, the main difference between the Osmo UV Protection Oil (410) and Osmo UV Protection Oil Extra (420) is that the 420 contains fungicides and biocides to protect against mould, algae and fungal growth. For this reason, the 410, which doesn’t contain fungicides and biocides, can be used on interior and exterior wood surfaces whereas the 420 is designated for exterior use only.
- Clear Natural Oil-based finish with UV-Protection Factor 12
- Very water and dirt resistant
- Reduces wood swelling and shrinkage
- Osmo UV-Protection-Oil EXTRA 420 is safe for humans, plants and animals once dry
- Microporous, breathable finish which does not crack, peel, flake or blister
- No sanding necessary for future applications
Ensure that wood surfaces to be treated with Osmo UV Protection Oil 420 are clean, dry and frost-free (moisture content max. 20%).
- 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.
- 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 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
Oiled surfaces can be regularly cleaned with a suitable exterior spray cleaner that won’t strip away the waxes and oils.
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.
