A method for applying a metal on a substrate comprises: a) applying a coating by treatment in a plasma, comprising a compound selected from alkanes up to 10 carbon atoms, and unsaturated monomers, and b1) producing polymers on the surface of the substrate, the polymers comprising carboxylic groups and adsorbed ions of a second metal, reducing the ions to the second metal, or alternatively b2) producing polymers on the surface, bringing the surface of the substrate in contact with a dispersion of colloidal metal particles of at least one second metal, and c) depositing the first metal on the second metal. Advantages include that materials sensitive to, for instance, low pH or solvents can be coated. Substrates including glass, SiO.sub.2 with very few or no abstractable hydrogen atoms as well as polymer materials containing halogen atoms can be coated with good adhesion.
