Osmo UV-Protection Oil is highly recommended for garden furniture, timber frames and structures, pergolas, and exterior surfaces. Osmo’s is the perfect stain to reduce wood discolouration and greying. The natural oils enhance the natural character and tone of the wood. It is a semi-transparent, satin exterior wood finish that is a satin-matt, natural oil based, and microporous finish, that does not crack, flake, peel or blister. It allows for a breathable surface that is very durable, water repellent, moisture regulating, and is weather and UV resistant.
