The present invention relates to a method of coating substrates, especially those with a hydrophobic surface, in which the substrate to be coated is coated with a coating composition whose binder is a formulation comprising an aqueous polymer dispersion in which the polymer has carbonyl or oxirane groups (component a)), and at least one compound having at least two NH.sub.2 groups per molecule, is applied to the substrate to be coated [sic]. It also relates to coating compositions including such binder formulations, and furthermore to a method of sealing using a sealing composition including such formulations as its binder.
