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

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)
Coverage
Coats
- 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.
