What separates the really good contractor from the competition is attention to detail and consistency, especially with the finishing near edges, block-outs, drains, clean-outs, and other penetrations. Except for the best finishers, this detail work is fast becoming a lost art.
Finishing concrete has always been about timing: being in the right place at the right time with the right tool. With the now widespread acceptance of the F-number system, good power troweling techniques are essential since floor flatness depends directly on a finisher's ability to run trowel machines.
Using float pans, which are attached to the blades of walk-behind or nonoverlapping ride-on power trowels, offers finishers several advantages, including increased productivity, flatter floors, easier transition from wet to dry areas when floating and superior ability to break open the concrete surface. To obtain the benefits from these advantages, however, finishers must learn how to use the pans properly.
