Layer systems and methods using such layer systems

A layer system for application to a carrier for protective or decorative purposes, wherein the layer system comprises:

• an application layer assembly comprising at least one functional layer and an adhesive applied to at least a portion of the functional layer and configured to adhesively adhere the application layer assembly to the carrier;
• and
• a transport layer assembly comprising at least one carrier layer and an adhesive applied to at least a portion of the carrier layer and adhesively adhering the transport layer assembly to the application layer assembly;
• wherein the transport layer assembly comprises a release tab and a correction tab provided at different sides of the transport layer assembly and which extend beyond the application layer assembly such that they can be grasped by the hand of a user without grasping the application layer assembly;
• and
• wherein the adhesive of the application layer assembly and the adhesive of the transport layer assembly are adjusted relative to each other such that the application layer assembly can be released from the carrier by pulling at the correction tab while the adhesive adherence of the transport layer assembly to the application layer assembly is maintained, and such that the transport layer assembly can be released from the application layer assembly by pulling at the release tab while the adhesive adherence of the application layer assembly to the carrier is maintained.
