Should have no problems with the grinding but be careful when your polishing or it will turn the grout grey. If it does just use some Nano Scrub to get it out.<br><br><div class="gmail_quote">On Tue, Jan 17, 2012 at 7:28 PM, Mike Marsoun <span dir="ltr">&lt;<a target="_top" href="mailto:nulifesc@bigpond.com">nulifesc@bigpond.com</a>&gt;</span> wrote:<br>

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 &quot;coke&quot; 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???<br>
