The usage instructions are recommendations based on the tests we have conducted and our experience; carry out your own tests before each application. We do not assume any liability for a specific application result due to the large number of applications and storage and processing conditions. If our free customer support service provides technical information or acts in an advisory capacity, no responsibility is assumed by this service except where the advice or information given falls within the scope of our specified, contractually agreed service or where the advisor was acting with wilful intent. We guarantee the consistent quality of our products. We reserve the right to make technical changes and carry out further development.
