How many sq ft is your floor.
It sounds like you haven't flattened a floor before.
The first one you do-no matter how you prepare for it will be challenging.
It will definitely take more time than you will plan for!
The onyx will cut fast-there are other issues to be more concerned with.
What type of machine do you run, pad drivers, diamonds and how you place or affix them so you aren't chasing them for the better part of the day.
Its your choice which metal grit you will start with but for onyx I would start with a 70 metal full face tool with a good bevel.
Then run a 120 grit copper to transition to resin diamonds. Take it too 800 grit and polish.
You will need a good system for polishing as onyx will etch easily.
What type of grout was used and how extreme is the lippage. Those two questions are key to your success.

In terms of grinding time, does it take a lot longer to grind onyx than marble...I though onyx was much harder... trying to get an idea of how long it will take..thanks again,,! Steve

Subject: [sccpartners] onyx vanity


To everyone,
We are doing a restoration job for an entire apartment in Manhattan and they have a onyx vanity and sink in one of the bathroom which have become dull and needs some facelift .
They were originally polished, but across time and use they have lost their
sheen. I have no experience with onyx. Does it polish like marble? Is it
hard like granite? I haven't the slightest idea. Any experience out
there polishing this stone?
