Product Description

Osmo Deck oil Anti-Slip is a Satin finish top-coat, for decking which has already been treated with a coloured oil. Contains a special highly compressed organic non-slip additive, which is evenly distributed in the coating and prevents slips when dry. The microporous surface allows the wood to breathe and reduces swelling and shrinkage.

The water-repellent natural oil-based surface does not crack, peel, flake or blister. No sanding necessary, just simply recoat.
Deck oil anti-slip contains active ingredients that offer protection against mould, algae and fungal attack.

  • Coverage: Up to 24m² per Litre
  • Drying time approx. 12 hours (based on 23°C/50% Relative Humidity)


Wood surface must be clean, dry and frost-free. 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. Wear a dust mask when sanding. If possible, apply a base coat to all sides before installation.

Fresh wood, and especially hardwood needs to weather (for approximately 6 weeks) after installation. This weathering period helps the wood to become more absorbent, allowing the oil to penetrate the surface. A base coat with a pigmented oil is recommended, e.g. Osmo Decking-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 recommended, especially for unfamiliar surfaces.
If additional protection against blue stain, rot and insects is required, pre-treat the wood on all sides with Osmo WR Base Coat*.
*Use biocides safely. Always read the label and product information before use.


  • Apply thinly and evenly to the clean and dry wood along the wood grain with a Natural Bristle Brush and spread well.
  • For quicker application on larger areas, we recommend the Osmo Floor Brush 150 mm which is tailored for decking and allows you to work ergonomically.
  • Allow to dry for approx. 12 hours with good ventilation.


Areas that have worn can simply be refreshed by applying a fresh coat of oil. Areas with damage such as scratches can be repaired by lightly sanding and re-applying the oil.
