These products, in powder form, are recommended for polishing all types of granite. Thanks to the use of high-level abrasives in these products, a perfect polish can be obtained. The complete absence of chemical polish, specifically oxalic acid, avoids causing friction heat on the marble surface, thereby preventing oxalic acid “burn" marks. At the same time, the presence of metallic powder assures a seal that covers even the smallest surface imperfections. The granular dimensions of the powder (fineness) have been exhaustively researched, formulated and balanced to allow for the fastest and most economical machine polishing on marble that is pre-polished at 400 or even 600 grain; these products will yield a completely stable and long-lasting polish.
