DIY polishing granite and marble slabs

Hi. Has anyone had any success at DIY polishing old granite, marble or Caesarstone slabs.

I’ve got some salvaged black granite at the the moment. I cut it to the appropriate size for a vanity top without any problem, but polishing the edge is beyond me. I can get it close but just never really glossy. I have from 100 to 6000 grits which I apply sequentially but somehow the result just doesn’t come.

I’m thinking if I could at least polish the edges that would be good. I don’t expect to be able to repolish the flat surfaces although if someone has done that successfully then let’s hear about it.

Over the years I’ve had quite a few salvaged slabs that I should have been able to do something with - including a mountain of Carrara marble salvaged from a very rich persons bathroom - I should have been able to do something with that but foolishly I just gave it away or dumped it.

Anyone done this?

Hi Arron
i found this worked on some Aldi terrazzo platters & it gives nice finish.
Lithofin MN polish Made in Germany but posted from Victoria.

all I know is use and wear really QUALITY breathing aspirators that stuff in your lungs is the new MDF /asbestos epidemic

My mate who is a Memorial Mason wet polishes granite edges at equivalent to 12,000.

Yes, I see that as an alternate approach. Stop polishing early and don’t get too worried about the surface, and then wax it. You’re basically just polishing the wax, not the stone. I had a friend who was a marble cutter who told me that the majority of slabs were done that way. He regarded it as a scam because the customer believed they were buying a slab mechanically ground to a high polish, but they were in fact buying a slab ground to a low standard and then polished with wax. The problem was in how long the wax coat lasted as the customer was locked into occasionally repolishing with wax, forever.

I should try my surfaces with some easily obtainable wax, like car wax, and see what happens. I don’t mind cheating and I d9nt mind wax polishing occasionally.

Thanks for fresh perspective.
