Commonly referred to as “5X Powder”, is a very effective way to polish all Marbles, Limestone, Terrazzo and other calcium containing stone. 5X is also a great polishing method
for properly honed concrete.
I had damaged black marble tiles in the kitchen after bottle of CLR had spilled all over my floor. I have wet sanded them all with three different grit numbers from 600-1500. I have polished them with different final products and nothing brought glossy finish until I used this powder. This powder worked great. After wet polishing with this powder, my tiles are almost like brand new again. They got their mirror finish back. It also made tiles nonslip. One recommendation is to use face mask. This powder releases some strong scented chemical in the air that made me choke couple of times when I was too close to it.
