Hey partners have a verde wall installed in the 1950s.  Used marble diamonds 50 all the way to 3000 and granite polishing powder (dark) and it came out wonderful for demo.  My question is it has green grout lines will they darken, and  if so how can I get it back to its original color?  If you have any other ideas please your input is valuable
