The industrial diamond abrasive incorporated into these pads greatly increases the effectiveness and the efficiency of the polishing process, so much so that existing floor polishing and grinding machines cannot fully exploit the potentials of these state-of-the art polishing pads. The diamond-impregnated polishing pads are much more effective and capable of stripping off material from the exposed surface of concrete and stone flooring to achieve a very smooth, high luster, polished surface. The diamonds in the pads can dig into the extruding surface material to a much greater degree compared to earlier pad types and can strip the extruding layer of material off much easier compared to pads previously available. The diamond impregnated pads can also continue to remove material more effectively at a given smoother grade of pad (e.g. grit rating) and achieve a smoother finish than identically rated pads. Newer diamond-polishing technology now makes it possible to grind and polish concrete surfaces at up to 3000-grit finishes. These finely polished concrete floors are essentially no-maintenance flooring. Removing all previous treatments and then polishing the floor can be a one-time fix that reduces maintenance costs, minimizing any requirement for expensive waxes or other coatings. After diamond polishing, the only maintenance required is the removal of dirt, oils, and other foreign substances that can stain the concrete. Currently, most vendors of stone or concrete floor polishing services use a conventional single-pad rotary buffer machine operated by a single worker with a diamond- impregnated polishing pad attached. Such machines are limited in effecti
