MB Stone Care MB-12 Polishing Powder for Marble is MAURIZIO BERTOLI'S OWN BRAINCHILD AND INCREDIBLE BREAKTHROUGH!! No polishing powder on the market can be even remotely compared to it! The least result that can be expected is "as factory-finish." In the VAST majority of cases the final result is always better than "factory." It works "miracles" on green marbles, always delivering a gloss obviously higher than the "factory polish!" Black marbles, dark brown marbles, extremely delicate marbles (Botticino), dolomitic marbles? NO PROBLEM! MB Stone Care MB-12 Polishing Powder for Stone is specifically designed for "Dry-polishing," although it could also be used for wet-polishing. It enables a well trained operator to polish between 1200 and 2500 square feet per shift, depending on the marble (including coffee breaks!). What's more, it works incredibly well on many "granites," including - but not limited to - Black Absolute, both on floors and countertops. This is a HazMat (hazardous material). It can only be shipped via UPS Ground Delivery to the continental USA or UPS Standard Delivery to Canada. It is not able to be shipped via any other level of service or outside of the continental USA and Canada. Ships to CONTINENTAL U.S.A. and Canada only-- it is not available for delivery to Alaska or Hawaii.
