We have a couple shiny marble floor tiles with scratches. Will these grind out the scratches and restore the shine?

Yes, they will work for your marble tiles. Good technique is important. When you finish polishing marble with these pads, end with special marble polishing power or creams, then seal. Have not had a problem matching the high factory sheen.thanks.

I am only looking to polish my granite countertops. i have no idea which grit to use? do i have to spray water? i don’t want to damage them. help!

Hello my friend. Yes, you need to used with water. 50# is coarse grinding. 3000# is fine grinding. If you granite counters are coarse, please polishing from 50# to 3000#. If you granite counters are a little shine and you just want to polishing it to more shine, please use 1500# and 3000#. There are no standard methods for the instructions. It depends on you and your stone. Thank you.

Will these help me chamfer porcelain tile edges?

It can use on tile edges, but not the best effect. You can buy 1 set and have a try. Thanks.
