Osmo UV Protection Oil provides a protective finish in a beautiful satin sheen for exterior vertical woodwork. The clear finish enhances the wood’s natural beauty and character. Two coats can be applied to the timber for optimum protection and a warm rich effect, or the finish can be used as a top coat for wood previously colour treated (such as Osmo Country Colour).



  • A professional solvent-based UV-resistant wood oil
  • Outstanding durability against weathering
  • The 420 Extra contains active biocides to protect wood against mould, algae and fungal attack
  • 410 is without biocides – a more ‘eco friendly’ finish
  • Very easy to maintain and patch repair if required
