Guys I have marble floors that are not dull. They have minimal wear and tear. If I want to polish them and shine them up can I use the spynergy pads and what grits should I use?
it depends on what you call minimal wear and tear. are there scratches? how deep? can you put a light bulb above the most damaged areas and see the reflection of the entire light bulb or it looks blurry. Whatever the case may be, you can use the pads but you will need to test and determine the grit to be used and on which areas of the floor and finish the entire floor with 11,0000 or powder polish.
As Martin described, it depends upon exactly what "minimal wear and tear" is and also how much gloss you want when you finish.
Based on what "minimal wear and tear" means to me and expecting you want a high gloss, I would clean the floor, polish with the 8,000 grit Spinergy pad, clean off the slurry and then polish with the 11,000 grit pad.
