I finally listened to my old foreman about using a magnesium float on that big slab in Phoenix.
He said 'it'll close the surface better than aluminum in that heat' and he was right, we got a much smoother finish before the bleed water even showed. Anyone else have a go-to tool for hot weather pours?

Wait, you didn't use a mag float before?

Man, I was the same way! Thought my old aluminum float was good enough for everything. Then I had to do a big garage floor in the middle of August, and the mix was setting up way too fast. The mag float didn't just smooth it, it actually bought me a few extra minutes to work the edges before it got away from me. Totally changed my mind on hot weather pours.

Funny how some old-school advice turns out to be the best. For years I stuck with aluminum, figuring it was just fine. My old foreman would shake his head at me, just like stellaa69 probably is now. That Phoenix job proved him right, the mag float really did handle the set-up in the heat differently. It closed the surface up so tight and smooth, it made the next steps easier. Sometimes you have to see it with your own eyes to change your mind.
