A clear satin-matt decking oil finish with anti-slip properties for previously oiled decking. Osmo Anti Slip Decking Oil is perfect for use on all exterior wooden decking boards, steps and staircases, including douglas fir, bangkirai, garapa, massaranduba, larch and pine.

Osmo Anti-Slip Decking Oil is a satin top coat for decking already treated with coloured oil. It contains a special highly compressed organic non-slip additive, which is evenly distributed in the coating and prevents slips when dry. The coating contains active ingredients that create a preventive protection against mould, algae and fungal attack. Osmo Anti-Slip Decking Oil is especially suitable for all exterior wooden decking and stairs made of e.g. Bangkirai, Massaranduba, Garapa, Larch, Douglas Fir or Pine as well as ribbed, grooved and particularly for smooth decking surfaces.



  • Extends the durability of pigmented oil-based finishes
  • Designed as an anti-slip finish for previously oiled, exterior surfaces
  • Water & weather repellent

Wood surface must be clean, dry and frost-free (moisture content max. 20%).

Osmo Anti-Slip Decking Oil is ready to use, please do not thin. Stir well before use. Clean old microporous stains thoroughly. Old paints and lacquers must be completely removed. As a rule, wear a dust mask during sanding works. If possible, please apply base coat to all sides before installation.

Fresh wood, containing natural wood ingredients and especially hard wood needs to weather off (for approximately 6 weeks) after installation. Thereby the wood becomes absorbent and the wood finish adheres optimally.

A base coat with a pigmented oil is recommended, e.g. Osmo Bangkirai-Oil, Larch-Oil or Douglas Fir-Oil or Osmo Natural Oil Woodstain. Osmo Anti-Slip Decking Oil acts as protection against weathering and extends the life of the coating.

Already greyed or weathered wood should be refreshed and cleaned with Osmo Wood Reviver Power-Gel. The finished surface is, among other things, influenced by the wood‘s natural characteristics. Therefore, a trial application is always required, especially for unfamiliar surfaces.

If additional protection against blue stain, rot and insects is desired, pre-treat the wood if possible on all sides with Osmo WR Base Coat*. *Use biocides safely. Always read label and product information before use.


Apply thinly and evenly to the clean and dry wood along the wood grain with Osmo Soft Tip Brush and spread well.

For quicker application on larger areas, we recommend our Osmo Floor Brush which is tailored for decking and allows you to work ergonomically.

Allow to dry for approx. 12 hours with good ventilation. When renovating, one coat applied to the clean and dry surface is usually sufficient.

Exterior wood naturally greys over time and therefore must be protected to maintain the natural colour. Osmo Anti-Slip Decking Oil is clear and therefore it offers only limited protection against UV rays from the sun (greying). Anti-slip decking oil is recommended as a top coat. With a combination of a coloured base coat and one coat of Osmo Anti-Slip Decking Oil as a top coat, your decking is fully protected. Anti-Slip Decking Oil is not suitable as a self-priming finish. Oils enhance the natural tone of wood (permanent wet effect). Use decking oil to produce a slip-resistant surface once Osmo UV Protection Oil has already been applied.

To avoid greying and declining non-slip effect on high traffic areas, these areas should be partly recoated at the right time.

If the greying process has already begun, refresh the surface with Osmo Wood Reviver Power Gel and recoat.

Many wood species contain water-soluble coloured extractives which may leach out naturally when weathered.
