Osmo Anti-slip Decking Oil acts as a top coat for previously stained, coated or finished wood decking for an anti-slip surface. Osmo Anti-slip decking oil contains compressed particles, which evenly disperse within the finish and create the anti-slip surface once dry. 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.
