Had a total panic moment with a hot load on a driveway job in Tacoma
We were finishing a big stamped driveway, about 1,200 square feet, and the truck was running late. It was pushing 85 degrees that afternoon. By the time the concrete hit the forms, it was setting up way faster than we planned. I started stamping the first section and the texture just wasn't taking right, it was pulling and tearing. My helper looked at me and said, 'Boss, we're gonna lose it.' I called for the water truck we had on standby for curing and had them give the whole pour a super light mist, just enough to buy us maybe ten more minutes of work time without washing out the cream. We switched to a faster stamping pattern and got it done. It was a close one. What's your go-to move when the mix starts to set up too fast on a hot day?

Honestly sounds like you made it a bigger deal than it was. A light mist from the water truck is just basic hot weather work. That mix was still plenty workable if the texture was just starting to pull. Seen way worse where the concrete actually starts to crumble. You just work faster and stop overthinking it.

But ryan_hart38, that light mist changes the surface water ratio and can weaken the top layer. Starting to pull means you're already fighting the clock for a good finish. Calling it overthinking ignores real mix design science.
