    • The invention relates to a method for coating microporous surfaces, comprising pores with a width from 10 to 1.500 nm, by coating the surface in question with at least one coating material which may be hardened thermally, or by actinic radiation, whereupon the resulting layer(s) is/are hardened thermally and with actinic radiation. The coating material or one of the coating materials (a1) comprises at least one component (a11) with, as a statistical mean, at least two functional groups per molecule with at least one bond which may be activated by actinic radiation and which serves for cross-linking with actinic radiation and, optionally, (a12) at least one isocyanate reactive group, (a2) at least one thermally setting component with at least two isocyanate reactive groups and (a3) at least one polyisocyanate.
