Saw a finisher in Tucson pull a slab too early in 108 degree heat and the whole thing crazed by lunch
I was on a big pour at a shopping center in Tucson last July when the guy next to me started finishing his section while the bleed water was still sitting on top. His half looked fine for about an hour, then the surface went patchy and started cracking from the edge in. How do you all judge when the bleed water is gone and it is actually ready to get on a knee board?
