I used a garden sprayer to mist a slab in Phoenix heat and it backfired
We were finishing a driveway in Phoenix last Tuesday, and the forecast said 108 degrees. I thought I'd be clever and brought a clean garden sprayer to mist the surface, hoping to slow the set. Instead, the water beaded up on the cream and created a weird, pitted texture as we troweled. The foreman said the mix was already too hot and the mist just sat on top. Has anyone else had a curing method go wrong in extreme heat?

Honestly that sounds like a minor cosmetic issue more than a real problem. A few pits on the surface won't make the slab fail. Concrete sets crazy fast in that heat anyway, so any troweling was probably a long shot. The foreman was right about the water just sitting on top. Next time maybe just start way earlier in the morning.
