Q.: Is there an advantage to using a disc-type powerboat instead of the conventional troweling machine with float shoes during the floating of a floor?

A.: The two are about equivalent in performance, though if the troweling machine is one of the large, 4 foot-diameter type, it probably produces a better planing action, giving a flatter floor. The troweling machine should never be used for floating without the float shoes attached. There are also all-purpose blade machines that do not require float shoes, but some authorities say it is easy to get in trouble with them by accidentally using the trowel setting for floating.
