As such these grain sizes can be indicated differently. The result is that it can be difficult to determine how fine or coarse a specific stone really is. Some suppliers prefer to give the absolute grain size in microns, others adhere to standard European sizes and yet another prefers the Japanese version.
What Abrasives can be used for SSPC-SP 6 Commercial Blast Cleaning? Abrasives are used for grinding, polishing, or cleaning hard surfaces. SSPC-SP 6/NACE No. 3 calls for the use of abrasives in the methods listed. The abrasives selected for this method depend on a variety of factors.
A. Hi, S P S. You can't measure the things that are covered by Sa 2.5, like discoloration, visible oil, and greyness with a profilometer. Nor should we reasonably expect a given surface profile to consistently result simply by complying with a blast cleaning specification that is unconcerned about it, and which apparently permits the use blasting grit of any …

I'd say it's hard to tell. For example I sometimes use my Dovo green paste and read somewhere that it's supposed to be a bout 6 microns. So in that case the paste should be well suited for removing metal from the edge at a good rate but it doesn't seem to do that very well. It'll still polish the edge even after very high grit stones.
