2,5l Bog Oak Decking Oil

Natural oil based protective finish for exterior wood that does not peel, crack, flake or blister

  • Microporous, breathable finish allowing the wood to breath and reduces the risk of swelling and shrinkage
  • Water-repellent, extremely weather and UV resistant

Easy to apply as well as renew, no sanding or primer necessary

  • When dry, the finish is safe for humans, animals and plants and is suitable for children’s toys as per EN 71.3 (European norm)


  • 24m²/L with one coat


  • 2 coats, or one colour coat plus top coat of Osmo Anti-Slip Decking Oil 430

Surface Preparation

  • Bare wood species with a high content of natural wood extractives need to weather off (min. 4 weeks) before the initial treatment 
  • Resinous wood, such as Larch or Douglas Fir, needs to weather off for at least 6 weeks to improve absorbency
  • Pressure impregnated wood and tropical species like Massaranduba, Bangkirai, Garapa, Iroko need to weather off for at least 3 months
  • Cedar requires a 3 month weathering period to improve absorbency
  • Greyed and weathered wood can be refreshed with Osmo Wood Reviver Power-Gel before applying Osmo Decking Oils
  • Avoid using jet / power washers to clean the surface as they can significantly affect the coverage of Osmo Decking Oils
  • Wood surface must be clean, dry and frost-free (moisture content max. 20%)
  • Osmo Decking-Oil is ready to use
  • Do not thin
  • Stir well using a flat stirring stick or spatula before use
  • Thoroughly clean or lightly sand old microporous stains or completely remove old varnishes before application
  • If any sanding works are carried out some fresh wood species must be weathered as directed above to improve absorbency once more
  • Sanding to finishing grades of no more than a P120 grit are recommended
  • Always wear a dust mask when sanding
  • If possible, and if the wood is absorbent, please apply the first coat to all sides before installation
  • The finished surface is influenced by several factors, including the condition of the wood
  • Therefore, a trial application is always required, especially for unfamiliar surfaces

Method of application

  • Use stiff brush  or a lint free cloth  and apply thinly and evenly to the clean and dry wood surface along wood grain
  • Allow for good ventilation while drying. Lower temperatures and higher humidity levels will delay drying
  • Once dry apply the second coat – also thinly
  • If a less intensive colour is desired, the second coat should be carried out with clear Anti-Slip Decking Oil 430  

Generally the more rich and dark the colour chosen, the higher the level of UV protection offered. 

Avoid applying clear Anti-Slip Decking Oil 430 as a stand alone finish as this offers limited UV protection.
