Tried a magnesium float versus a steel one on a 30-yard pour last Thursday.
The magnesium gave me a much smoother finish on that warm morning, but does anyone have a trick for when the concrete starts setting up too fast?

Forget the garden hose, that water trick @harper_gibson2 mentioned can mess with your mix if you're not careful. Have you tried keeping a retarder spray bottle on the truck for those emergency moments? My crew will sometimes pour a cooler slab in the morning shade first to buy time for the main pour. What's the fastest you've ever seen a slab set up on a hot day?

What, you didn't bring a priest to bless the pour and slow down the set? On those hot days it feels like you're racing the sun. I've seen guys use a light spray of water from a garden hose on the forms just before the pour, seems to buy a few minutes. But sometimes you just have to work faster and swear more.
