I use a window screen to sift my grout  when I run into this problem. It
works really good on both sanded and non sanded.  It sounds like old grout
to me. I see this problem enough to where I keep a screen sift in the truck.

Mike,

Many times when grout roll up in balls the grout is old and the Portland
cement actually goes bad and causes this problem.

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???
