Armando,
 
What 5X polishing powder are you using?? All 5X polishing powders are not made equal. If you are using  grand Quartz or Granite City Tools  or in some cases Braxton Braggs polishing powder they will not work as well as the real 5X that is imported from Italy.  I agree with Walter that you may need to hone higher .

Hi Walter

I ve done the white crystalizer before
Gives sorta Ok result but not that impressive- never tried the second thing you mentioned and will look into it
What are the ceramic polish brands?

Customer might be happy with a burnished coating if you know of a procedure

Super of you to offer help

Tks
Armando

Are you sure it's marble because it doesn't sound like it. You can always try the acid test. If 5X powder doesn't work I would try bringing it up (try 800 grit test area but you may have to go higher) and using white granite polishing powder along with crystallizer. There are also products on the market for polishing ceramic that may work but I would first try the granite polish.

Hi everyone;
 
I haven’t jumped into the discussion  group too often before but would like to start using this more frequently.
 
In the 12 or so years I’ve been involved in stone restoration some funny Carrera appears that I usually end up getting frustrated over. Perhaps you guys have as well and can offer some assistance.
 
The normal x powder finish after grinding has no normal effect on it. Crystallizing procedures also work marginally if at all.
Usually you are faced with a complete resin pad  procedure all the way to 3000 in order to have an effect.
 
In the past I have embarrassed myself with the client all too often by not being able to provide more than a so so result on this stuff.
 
Job has been butchered by someone else about ten years ago. Scratches aren’t the issue. About 1500 sq feet.
Haven’t honed too many existing polished marble jobs –only re polished  Any tricks??
 
Help!!
Armando
