Watched a guy float a driveway in 95 degree heat last August and it set up on him in 20 minutes
He kept adding water to the mix to keep it workable instead of just waiting for the sun to drop, and by the time he got to the last third the edges were already crusting. Cost him the whole pour on South Ash Street and he had to tear it out the next morning. Any of you got a go to move for hot weather pours besides just starting earlier?
