MB Stone Care MB-12 Polishing Powder for Stone (formerly MB-11/P) is MAURIZIO BERTOLI 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 a factory-finish. In the VAST majority of cases the final result is always better than a factory. It works miracles on green marbles, always delivering a gloss obviously higher than a 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 granite, including but not limited to Black Absolute, both on floors and counter tops. Note: packaging varies from picture shown for 1 lb size. Product comes in a ziploc bag.
