In simple terms yes but we would always recommend using a dedicated exterior wood oil over traditional oils such as Danish Oil or Teak Oil. Specialist exterior wood oils are formulated with a blend of oils, resins and UV filters that offer better durability, longevity and protection from Sun and weather damage, making them ideal for wooden cladding. These products tend to be available in both clear and coloured formulations so if cladding has been left untreated for a number of years and has turned grey or silver over time, the appearance can be restored.
