Paranoia is going to slow you down and force you to make the wrong decisions.
You can be as careful as you want and I’m the first to say test test test, but no matter what you do, no matter how many tests you do, you know that all of sudden the job still takes a turn for the worst sometimes
In this business you have to feel the stone, feel the procedure to get it right.
The moment I learned that, not a task in the world seemed complicated. I may not be able to explain what to do as well as some others on here, but I can’t believe anyone can feel the stone as I do, and for me that’s my secret to success. I will polish and do any stone in the dark.
Stephen, if you feel with your gut that it should be sealed, then do it, but attempt to polish the stone as chemical free as possible .
This pic I included is me doing that blind polishing for 8 hours, not one of my smartest moments but my attempt to contain dust when I had nothing else available.
I guess I'm a little paranoid
Many years ago I watched a seasoned pro have to re grout a new floor after the white honing powder became so attached to the grey grout even his 3000psi gun couldn't get it out. With MB12 or 5X I don't think it would be an issue (I've never seen it happen). The slurry from diamond sanding could get stuck in/on the grout. I even had the slurry stick to Spectra lock epoxy. Ron, start with 220 (If can) or higher to avoid framing that difficult to polish out.

Interesting method but why would it be necessary to do that in this case? And what was your reasoning or what were you attempting to do when you did all that? Did you have a grout problem?
Ron, I would maybe pre seal with a water based sealer, let cure then diamond polish to the highest clarity possible then tint your powder to match the grout with a concrete coloring powder or similar and use your spinner extractor. Years ago I did this on raven slate with black grout and it worked well. aloha

I looked @ a job of a newly installed polished mosaic marble floor. They used sanded grout. The floor was etched slightly when they used vinegar to clean off the grout film. The real problem is that the small tiles have a lot of scratches. In the past I have had no problem restoring marble floors with sanded grout. But this floor is not 12X12 tiles. Can I restore this floor without having the grout replaced with unsand grout? I thought of using my 13 inch floor machine, starting with 120 grit diamonds. The reason for using my 13 inch floor machine is that I’ve been told that a smaller diameter floor pad is less likely to leave picture framing. I do place a white pad between the machine and diamonds. . After 800 polish with polishing powder. I normally use 5X, but I’m concerned about 5X impacting the color of sanded grout. Any suggestions would be appreciated.
