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.
METHOD OF 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.
NOTE
Osmo Teak-Oil 007 is a clear decking oil finish and therefore offers only little protection against UV radiation (greying).
As a clear top coat for fence panels / screens, we recommend Osmo UV-Protection-Oil/UV-Protection-Oil Extra. For decking the clear Anti-Slip Decking Oil 430 should be applied over 1 x coat of a coloured Osmo Decking Oil. Clear Anti-Slip Decking oil 430 offers higher pigment protection which increases the durability of the finish against wear and weather.For especially mechanically loaded areas (e.g. decking), we recommend checking the finish at least once a year and to eventually recoat the surface with the appropriate finish.Due to their surface properties, ribbed or grooved as well as rough (sawn) wood surfaces absorb more product per square metre than smooth surfaces.
Many wood species contain water-soluble coloured extractives ( eg Larch ) which may leach out naturally when weathered. Weathered, bare wood surfaces can be refreshed with Osmo Wood Reviver Power-gel.
Using jet/power washers or multi-purpose cleaners will increase the frequency of maintenance and recoating.
NOTE
Regular Cleaning: Damp cleaning with diluted Osmo Decking Cleaner using Osmo Decking Cleaning Brush.
Occasional Maintenance: If necessary, intensive cleaning and refreshing using Osmo Wood Reviver Power Gel or Osmo Gard Clean ( for green growth).
Recoating: Simply re-apply one coat onto the clean and dry surface when signs of wear become visible.
OSMO DECKING BRUSH
Made with 100% natural bristles with soft tips which gives fine control in achieving the desired effect. 150 mm width fits perfectly between the grooves of the decking boards providing exceptional coverage capacities which produce professional looking results every time. Simply attach the Osmo extendable telescopic handle for applying in comfort.
OSMO ANTI-SLIP DECKING OIL
For a slip resistant decking surface, Osmo Anti-Slip Decking Oil 430 is recommended as the second and final coat over coloured Osmo Decking Oils.
OSMO WOOD REVIVER POWER GEL
Highly effective cleaning agent for the refreshing and cleaning of greyed and aged exterior wood. Especially developed so that it can be easily applied, even on vertical areas as it has a special non-drip formula. The deep penetrating effect of the gel removes the greyed patina, with results showing as quick as 30 minutes!
OSMO DECKING CLEANER
Osmo Decking Cleaner is a highly effective concentrate for cleaning untreated or oiled wooden decking and garden furniture. It is water soluble for quick, easy and thorough decking maintenance.
Top Tips:
-
For a clear and natural finish for decking, apply just two coats of 007 Teak Oil, which allows the wood to naturally grey over time.
-
The darker the colour, the slower the greying process of the wood will start to appear.
-
Osmo Anti-Slip Decking Oil 430 can be used as the second coat after any of the coloured Decking Oils to provide a slip resistant surface.
-
Recommended application is 35ml/m²

Osmo Decking-Oils protect, maintain and beautify the wood surface, producing a smooth, slightly satin finish which is extremely water resistant and dirt repellent. The microporous finishes are based on natural vegetable oils and allow the wood to breathe and regulated moisture content. By doing this swelling and shrinkage is reduced. The penetrated finish will not crack, flake, peel or blister.
RECOMMENDED
For all other wood types not mentioned, always trial apply first.

RECOMMENDED AFTER WEATHERING PERIOD
For the following wood types, a weathering period is recommended. Depending on wood species, new or freshly sanded wood requires up to 12 weeks (approximate) exposure to the exterior elements before application.
After the weathering period, it is generally recommended to clean the surface from the extractive content. Osmo Wood Reviver Power-Gel can be used to refresh the colour of the wood. If necessary and before application, de-grease the dried surface with Osmo Brush Cleaner and Thinner (degreaser), always trial apply!
For all other ingredient-rich hardwood species not mentioned may require a varied period of exposure. Please contact us for further information.
