Anyone know anything about concrete?

A 10x12 is not that big of an area where you couldn't do it yourself, and you could probably rent the trowels and floats from the rental center. The one thing you would need to have experience with is WHEN to mag it out, as concrete is a chemical reaction and needs to be finished at the right time. Most all concrete guys I know come and screet it out and then pour a case of beer on the lawn and cover it with ice. When the beers gone, it's time to float it out. Usually takes about an hour or so after it's poured, but like the Free Masons, they ain't givin' up their secrets, or any of their beer. That would throw their timing WAY off!!!LOL!!! Good luck with the pour, Geof
