Thank you all.
RAH, about the boiled linseed oil, diluted with 1: 1 turpentine, is used as a natural wood impregnating agent, also for floors. It penetrates into the pores of the wood filling and polymerizing it forms a sort of protective film resistant to UV rays and atmospheric agents. Therefore it is very suitable for the treatment of wood outdoors.
For these reasons I don t think mildews would like it. It is not a simple vegetable oil like olive oil, but it is an oil called "siccative" like tung. In any case, only the exposed boards have been impregnated and they are difficult to suffer from humidity stagnation.
