The Mohs Hardness Test Kit shows how strong the concrete surface really is, with a simple scratch test. Test before you start to see whether the floor needs a hardener first. Test again during the polishing process to follow how the surface improves, and at the end to check the final result and show it to your client.
Experience shows that a polishing process in several steps, with decoSIL, decoFINISH after the last step and then burnishing, can bring the surface to a Mohs hardness of 8 to 9.
