The weight of the components and the boiling points of the solvents are provided such that the first solvent is substantially already evaporated upon application on the surface (9) to be coated, whereas the second solvent evaporates substantially only after the application onto the surface (9) under formation of a hydrophobically acting layer attached to the surface (9).
