A warning from a guy at a supply yard in Phoenix that saved my hide
I was picking up a load of quick-set mix for a small patio job, maybe 5 years back. This old timer, Leo, who ran the yard, saw me loading the bags and just shook his head. He came over, put a hand on my truck, and said, 'You check the forecast for tonight?' I hadn't. He pointed at the sky and told me, 'They're calling for a 40 degree drop after sunset. You lay that down now, the top will skin over and the core heat will blow the surface to pieces by morning. Seen it ruin a $3,000 slab.' I waited a day, and he was dead right. That quick chat in the dust of his yard changed how I plan every pour now. Anyone else have a simple tip from an old hand that stopped a big mistake?
