Length - 04:03 Dustless grinders are used on a frequent basis to prepare a concrete floor for a concrete overlay or epoxy coating. This tool can also be used to remove sealers and light mastics. Surface preparation with these hand-held grinders is usual for indoor application where dust is a problem or in tight spaces where a walk-behind grinder will not fit. These are high powered machines so take the proper safety precautions. Dustless concrete floor grinders use a segmented diamond cup wheel to grind the surface. A shroud surrounds the cup-wheel to suction the airborne dust that is created during the grinding process. A smaller version of the dustless grinder can also be used for smaller concrete surfaces like concrete countertops, baseboards, or backsplashes. The smaller grinder also attaches to a vacuum that eliminates dust. This tool works with diamond pads in a variety of grits. Gradually grinding and polishing from a 50 grit to up to a 3000 grit will produce a high luster sheen. Be sure to wear the proper safety gear: eye glasses, ear plugs, dust mask and leather gloves.
