Surface Preparation
Bare wood species with a high content of natural wood extractives need to weather off (min. 4 weeks) before the initial treatment or be cleaned with Osmo Brush Cleaner and Thinner (degreaser).
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.
If additional protection against blue stain, rot and insect attack is desired ( eg soft woods) , pre-treat the wood, if possible on all sides, with Osmo WR Impregnation.
Application
Use stiff brush (Osmo Flat Brush) or a lint free cloth (e.g. for furniture) and apply thinly and evenly to the clean and dry wood surface along wood grain.
For a quick and easy application, we recommend using Osmo Decking Brush (150 mm) which was tailor-made for decking and allows you to apply the finish while standing.
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.
