Always start the floating perpendicular to the screeding direction and maneuver the trowel perpendicular to the previous direction. Floating in both directions creates a more flat and leveled finish compared to focusing on one direction.

Consider the speed and the number of passes during the floating process. Technically, the number of passes depends on the concrete slump, the admixtures, the weather as well as the desired finish of the slab. Usually, it takes 4 or more passes to get the desired finish. Always consider using the minimum speed during the start so you can control the direction and movement of the power trowel.
