A method for applying a heat insulation layer ( 11, 12, 13 ) or a metallic protective layer to a thermally stressed component ( 200 ) having a basic material ( 10 ) in order to eliminate local damage ( 14 ) or an untreated place in the coating, includes, in a first step, pretreating the local damage ( 14 ) or untreated place, and, in a second step, applying layers ( 17, 18 ) necessary for eliminating the local damage ( 14 ) or untreated place. A markedly improved lifetime of the processed component can be achieved in that, within the first step, the edge regions ( 15 ) of the layers ( 11, 12, 13 ) ending at the local damage ( 14 ) or untreated place are processed so that they form uniformly sloped and terrace-shaped edge regions ( 16 ). Furthermore, a precharacterization of the entire coated region of the operationally stressed component or critical places by FSECT makes it possible to reduce the risk in terms of otherwise overlooked layer regions, the remaining lifetime of which would not persist for the following operating time.
