WERKMASTER MOHS HARDNESS TEST KIT

The WerkMaster MOHS Concrete Scratch Tester is used to determine the hardness of concrete prior to starting any concrete surface prep or concrete polishing job. Concrete is made up of various elements of different hardness and densities that vary from region to region. The results of the scratch test will help you determine whether to use soft, medium or hard bond diamond abrasive tools to efficiently grind and polish the concrete floor.
