Osmo Deck Oil is a satin-matt, clear or transparent exterior wood finish. It will not crack, peel, flake or blister. It is water-repellent, UV*, and weather-resistant. With two coats on raw wood and one coat for renovation with no sanding or stripping between applications, it enhances the grain and natural beauty of decking, creating a protected smooth surface. Osmo Deck Oil is natural oil based and micro-porous, allowing the wood to breathe. Osmo Deck Oil has a uniquely low solvent content which accounts for its exceptionally large coverage rate - 2 to 4 times that of traditional deck treatments when applied using an Osmo brush. Osmo Deck Oil works excellent on both domestic and exotic species.Osmo Deck Oil is available in 7 natural wood shades to match the most commonly used wood species, as well as clear. Trial application is recommended to ensure best results.
