I have dealt with this oil two months ago balcony parquet Thermo Ash and am very happy with the result. The wood looks like new. There seems to be a good durable protective layer. The use is very simple. A uniform application functions without problems and without large expenditure of time. After cleaning with a mild neutral soapy water and drying overnight it takes no more than half a day for an average size balcony. After 4-5 hrs. Drying time by 20 degrees (without rain :-)) the surface is walkable. I would recommend the Osmo product fully.
