Please for help from Mr.Maurizio (or anyone who can help).
I try to become a professional granite craftsman so i decide to ask experts.
My problem is that with polishing nero assoluto(absolute black), nero africa, and specialy with star galaxy(glack galaxy granite). I try to remove deep scrathes and use grids 50,120,220,400,800,1500,3600,BUFF in wet diamond disks. I do not have automatic slab polishing machines and radial arm does not gives me the best result. The problem is that the polished look that my granite slabs provider is something I can not get in every way!. In my attempt the surface looks more physical, more "Black" from the factory polished surface (not burned by overpressure or heating during the griding), but not shiny as it comes from the factory. I asked a lot of "specialists" (abrasives salesmen). I tried a lot of methods (high or low grider speed,water sandpapers) but tha final result is "like" the original surface but not the same. I think something chemical (like oxalic acid for marble) is missing. Is thereIs there any way i can get the same polishing degre.? What tin oxide does? Is BUFF usefull? Are dimand powders usefull? What the fu.. have automated slabs polishing machines that we can not use by hand?
Too many questions? Ok let them.... unanswered...
But please...
What do you suggest? Please analyze me the whole procedure as detailed as you can please tell me product names and brands that you have use and had the best result.
Thank you Very much Mr.Maurizio
