Learned a hard lesson on a driveway pour in Phoenix last July

The sun was hitting the slab so hard that the edges started crusting over before I could even get the bull float on it. Has anyone else dealt with extreme heat messing up your timing on big flatwork jobs?

That bit about the edges crusting over before you could get the bull float on it - man, that brings back a story a buddy of mine told me. He was doing a big patio pour outside of Tucson, same time of year, July. He said he mixed the concrete a little wetter than usual to buy some time, but the sun was just brutal. By the time he got the bull float started, the edges had this weird, dry skin on them, like a sunburn. He tried to work it in but ended up with these ugly crust lines along the edges, basically had to rip out a whole section and repour it the next day, only this time with a tarp and some shade cloth. That heat is no joke, it just sucks the moisture right out of the slab before you can even blink.

@sam_wood60 that hurts just reading it. I did a driveway in Mesa last August and the mix was setting before I could even get the float on it, ended up with a rough finish that looked like hell.
