Process for preparing turbine blades or vanes for a subsequent treatment, for example the application of a coating and/or a material-removing operation, wherein the turbine blade or vane has an airfoil, which is delimited at at least one end by an endplate with peripheral surfaces, wherein at least one of the peripheral surfaces is at least partially covered prior to the treatment of the turbine blade or vane. In the process a covering strip is fitted onto at least one peripheral surface to form a plug connection.

Disclosed is a blasting device for blasting a part of a turbine blade, which has a blade root, a blade platform and a blade airfoil, with a blasting cubicle, which has an insertion opening, a blasting unit for the discharge of accelerated blasting media into the blasting cubicle, and a mounting for the turbine blade, wherein a seal is provided, which seals a gap between the mounting and the blade airfoil in the region of the insertion opening and so prevents the escape of dust, which is created when blasting, from the blasting cubicle, and wherein the seal seals the gap from the inner side of the cubicle.
