welp the wife and I did an inspection on the tile tonight. found lots of what I call pinholes in the grout and few broken pieces. now they get to come out and dig out the old grout and replace it correctly.
I wanted a grey grout but the wife wanted white. we ended up with white.
these two guys worked 11 hours on 1400 sq ft getting it ready. they were very, very meticulous in their work and you could see the pride they took. right now it looks smoother than concrete with nothing but sand and rock and packed tight. amazing!!
