Here is a marble floor maintenance and polishing case from a happy customer. See how could get the glossy result:

Floor: Marble Floor

Site: Plaza

Machine: 17"/430mm Single Disc Machine

Application step:  One step with Blue Pad and water only

Result: Marble floor from dull surface to glossy surface

Why Diamond Polishing Pad is different from traditional floor pad?

Diamond Polishing Pad can clean and polish the floor at the same time, but the traditional floor scrubber pad can only clean the floor surface, no polishing. They can't remove the scratches like diamond polishing pads. So clean with diamond polishing pad will make the floor shine stay longer and higher.
