Diamond tooling for grinding, levelling, and profiling concrete before a coating goes down.
Diamond tooling for concrete surface preparation and grinding. Before a coating can bond, the concrete has to be clean, sound and profiled, and diamond grinding removes old coatings, mastic, laitance and high spots while opening the surface. Our Reaper Cup segmented diamond cup wheels fit angle grinders on a 5/8-11 threaded arbor in 5 inch and 7 inch diameters. Choose the bond by concrete hardness, since a softer bond is matched to harder concrete: super soft bond for hard to very hard concrete, medium bond for medium hardness, and hard bond for soft or green concrete and abrasive overlays. Then choose the grit by job: 6 grit for aggressive coating and mastic removal, 16 grit for levelling and heavy stock removal, and 30 grit for profiling ahead of a coating. Use a dust extractor with every grinder.
