Competent finish folks do a nice job. That power trowel is the bomb in a good finishers hands. Wait a month, wash it with muriatic acid and paint it with epoxy. You'll have years of service out of the paint. I'm a huge fan of the stuff. Every floor in Philip Moris's factory in Richmond has the stuff. Well mostly anyhow. But realistically that can happen just as well in the spring after everything is built.
