The present invention refers to an improved method for applying silane-based coatings to solid surfaces, in particular metal surfaces, wherein a solid surface, in particular an optionally anodized or conversion-coated metal surface, is i) optionally cleaned, etched and/or desmutted, ii) brought into contact with at least one unhydrolyzed silane such that an unhydrolyzed silane layer is formed on the solid surface, iii) brought into contact with water such that the silane layer is at least partially hydrolyzed, iv) at least partially dried such that residues of water and alkanol are at least partially removed from the solid surface, v) optionally heated such that the at least partially hydrolyzed and least partially dried silane layer is cured, and vi) in case that step v) is conducted, optionally painted. The present invention also relates to an according silane-containing composition as well as to a solidsurface, in particular a metal surface, with an according silane-based coating and its use in the field of transportation industry or electrically conductive assembling.
