The Exterior Finish That's One Coat Only

This transparent, satin wood finish is based on natural oils for wood in outdoor areas. Unlike urethane finishes, which seal the wood off completely, it allows the wood to “breathe” and reduces swelling and shrinkage. It's water-repellent, extremely weatherproof and UV stable. Will not crack, peel, flake or blister. Osmo One Coat Only HS Plus works because it has high solid content, offering high coverage in just one coat. Maintenance is also a breeze, because you don't have to sand the finish to apply touch-ups. The dry finish is safe for humans, animals and plants. It is biocide free. 

This versatile product is suitable for use for many exterior wood surfaces, including timber cladding, carports, fences, pergolas, gazebos, patio furniture, and more. For decking, we recommend the Osmo Decking Oil. 

 

Note: Transparent colors are influenced by the natural color of the wood. Light transparent color tones offer limited UV protection and we do not recommend them for surfaces exposed to strong sunlight.
