My uncle told me to always use a wood float on a hot day, no matter what.
He swore it kept the surface from sealing up too fast. I tried it on a 90-degree pour in Phoenix last week and it gave me the best finish I've had all summer. Do you all have a go-to trick for working in extreme heat?

That wood float trick is solid, but in Phoenix 90 degrees is actually a cool day for concrete. When it hits 115, a wood float can still drag if the slab is setting up in 20 minutes. I keep a spray bottle with water and a fine mist setting to lightly fog the surface right before I make my final pass with the float. It buys you just enough time to close it up clean.

That spray bottle trick can actually weaken the surface layer over time.

Man, that heat sounds brutal.
