Hydrofluoric acid will work but it is very dangerous to use. I would walk away before using that acid

Hi Stu. Yes it is fantasy brown but the problem I have is it’s already installed with extremely expensive wall tile on top of it. Going to be tough to get up to the edges on the sides and backsplash.
Was hoping some type of acid honing

Fantasy Brown-its gets sold as Quartzite,Marble and or Granite.

It will be straight forward to hone just tedious.
Possible to use 70 then 120 grit electroplated pads then transition to a copper pad like a 120 or 220 then finish with honing powders.
It is classified as a marble-looks better honed-

My fabricator client installed this granite countertop and the homeowner decided they wanted honed instead.
Backsplash tile has already been installed.
Mechanically honing this is probably impossible at this point. I tried putting some acid on these samples and was able to get a very little reaction. Apparently there is some calcium in this material. The fabricator sells it as a marble.
Has anybody had experience with some type of chemical to get a nice even hone?

Thank you,
