Abstract

A process for repairing relatively small paint faults in powder coating layers, in which, in the region of the faulty point, a cutout is introduced into the powder coating layer with precisely defined dimensions with respect to its area and also with respect to its depth. A filler made of powder coating and/or a pre-product of the powder coating is introduced into the cutout. The filler is dimensioned to correspond to the volume of the cutout, in particular corresponding to the dimensions of the cutout, and is coherent. The filler introduced is joined, in particular bonded, to the powder coating layer arranged outside the cutout.
