"Just lightly misting the forms before pouring can help prevent sticking issues later on"
Wish I'd read this thread a week ago... spent my Saturday afternoon chiseling concrete off forms, and let's just say it wasn't exactly therapeutic. I'm usually skeptical about these little DIY hacks, but this one sounds legit enough to try next time. Cooler temps definitely helped, though—pouring concrete in midday heat is something I only needed to experience once. Lesson learned.

Yeah, pouring concrete in the heat is brutal... been there myself and it's not fun. Curious though, did you notice any difference in curing quality or cracking issues when pouring in cooler temps? I've heard mixed things about temperature affecting the final strength and finish, but haven't tested it out personally yet.
I've poured concrete in both hot and cooler weather, and honestly, cooler temps gave me fewer surface cracks and a smoother finish. But you gotta watch out—too cold and curing slows way down, which can weaken it. It's all about finding that sweet spot...
"It's all about finding that sweet spot..."
Couldn't agree more with this. I've had my share of concrete pours go sideways because of temperature swings. One time, we started pouring early in the morning thinking we'd beat the heat, but by noon it was scorching and we ended up with cracks everywhere. Learned that lesson the hard way.
Cooler weather definitely helps with surface finish, but yeah, too cold and you're stuck babysitting the slab forever waiting for it to cure. Had a foundation pour last fall where temps dropped unexpectedly overnight. We ended up tenting and heating the area just to keep things moving along. It worked out fine, but man, talk about extra hassle...
You're spot on—it's really about balance and keeping an eye on the forecast. Good luck with your next pour, sounds like you're getting the hang of it!
Interesting points, but do you think temperature alone is really the main culprit behind cracking? I've seen pours done in pretty extreme conditions that turned out fine because the mix design and curing methods were dialed in. Maybe it's less about chasing that perfect weather window and more about adjusting your concrete mix or curing strategy to handle whatever conditions you're facing... Just a thought.
