• restoring the desired dimension of the platform, the restoring comprising:
• applying material to the platform side face in such a manner that, after the material application, the platform is oversized, and
• machining the platform side face in order the to give the desired dimension to the platform,
• wherein the material application is effected with the material of an adhesion promoter layer,
• wherein the adhesion promoter material is applied within the scope of renewing a thermal barrier coating system of the turbine blade or vane which comprises an adhesion promoter layer and a thermal barrier coating, and
