The guys that pour concrete for a living keep the morning trucks booked full time. Since I’m not those guys a can’t just call down there and get a morning truck. They’ll bring all the noon concrete you want. For a footer it sucks to put down but it’s alright. You’d be in a real mess trying to do a floor in the heat.
When they poured my slab on a 90* day and after the guy power troweled it by 11am, he told me to keep it wet til night with the hose, bout every ten minutes that would dry right off and I could feel the heat coming from it.
