Because the grout is normally good quality resin, carborundum blocks tend to clog up if used for it's removal. The heat created during dry grinding tends to soften the resin and jam up the grinding blocks.

Diamonds cannot "clog" up, and are invariably used to remove grout. Typically a 25/36 grit diamond is used initially. The specification for the diamond matrix should be agreed with the manufacturers of the grinding disc in advance.

Fine grinding can be taken up to 10,000 grit to give the floor a mirror finish The finer end of the grinding spectrum is known as "diamond polishing." This is normally carried out as a wet process, but generates little in the way of slurry since it is only applying a diamond shine to the terrazzo floor.
