depends on the hardness of the particles.  Ask them what it is exactly and you should be able to look up the Mohs hardness..If its less than 3 you should be ok

Doing a agglomerate grind and just patched with a Polyblend ns grout. As I was scraping it back I could feel grit and it worried me. Called the manufacturer who said it does not have sand, BUT it has a particle of round shaped "coke" which is a by product of a mining process, the are tiny hollow balls that roll instead of scratch (when being spread) he said it is the same formula as the US Custom Polyblend. Worried about it scratching. Might have to scrub it out. Anybody hear of this???
