The coating of windows, doors or other components aims to achieve both an aesthetically pleasing appearance and a protective layer for any materials that are not naturally durable. It is critical that the correct coating system is used and applied using the right tools, in a suitable environment.

The Q-Mark Paint Application Scheme looks at the requirements for the pain system supplier and verifies that the paint application process is followed accordingly in a controlled and documented manner.

This scheme identifies approved people and approved coating systems for each certified company.
