As a water-resistant, water-based product, Osmo Anti-Slip Decking Oil provides an added safety element for decks. Osmo Anti-Slip Decking Oil is effective on smooth, grooved or ribbed decking surfaces of all wood materials, such as Yellow Balau, Ipe, Iroko, Pine, Southern Yellow Pine, Western Red Cedar and ThermoWood.

With excellent coverage rates and a simple application, Osmo Anti-Slip Decking Oil offers added assurance to exterior decking. No sanding is required prior to application, and a microporous finish allows the wood to breathe, protecting against cracking, blistering and peeling. 

As Osmo Anti-Slip Decking Oil is a top coat with no UV resistant pigments, it is not recommended as a standalone product. For optimal protection, finish the surface with a UV resistant penetrating oil before applying Anti-Slip Decking Oil.

Natural products

Osmo uses food-safe, natural ingredients for the basis of their wood finishes, waxes and pigments, including sunflower, soya, linseed and thistle oil, which is good for customers and wood alike.

Osmo products contain disaromatised white spirit to ensure finishes spread easily, removing the need for so-called "Green solvent" materials which can cause allergies.

Natural beauty of oils and waxes

Wood is a natural material, the cell structure, similar to our skin, can take on and release moisture, it breathes. To ensure that this exchange is not prevented we have created finishes especially suited to the character of the wood.

Osmo natural wood finishes are based on oils and waxes, the oil penetrates into the wood surface, protecting from deep within. The waxes form an elastic, micro-porous surface which protects the wood from external influences. The wood remains naturally beautiful, protected and durable.
