Abstract: A method for coating a surface, including the following steps: applying a layer of a curable composition to the surface; irradiating the curable composition with a first radiation having a wavelength of 100 to 280 nm, so as to give a partially cured composition; and irradiating the partially cured composition with a second radiation including at least one wavelength higher than the wavelength of the first radiation, and/or an electron beam, so as to give a cured composition, the curable composition including at least one compound curable by actinic radiation, and particles of at least one polyamide. Also, a coating layer obtained by such a method and to an object comprising a surface covered with such a coating layer.
