Have oiled with Osmo Bangkirai-oil my previously untreated three years old terrace (approx 3,5x4m) from Bangkirai wood and am excited about the result of the hue. Without previous Reviver a very natural color with a uniform color distribution has arisen again. The 2.5 l can, however, has only just passed for a 2-times very thin paint. Indicated on the packaging promises 60m². With a serrated / notched surface and slightly older wood you would have to expect a significant additional demand it. In addition, it would have a very water-repellent surface probably requires a thicker or 3.Anstrich. Because I can make no statement about the durability, first there is 4 stars.
