Power floats have an electric motor or petrol engine fixed over a circular pan or skimmer which smooths concrete before hardened steel reversible metal blades rotate at up to 150 rpm over the surface to create a hardened finish . Before power floating the concrete must be left to partially set, having been leveled and tamped.

How do float switches work?
Water Level Control’s NEW Float switches work by using probes (instead of floats) to detect or (sense) water levels in a storage tank (water, oil, gas, etc). The sensor probes actually act as their own sensors and do not pass electricity through the probes which keeps them from fouling, degrading and deteriorating.
What is floating and how does it work?
Floating usually starts at one end of the slab and moves to the other. The operator holds the float at waist- height and moves backwards so that the float removes their footprints. The speed should be slow and consistent. Once the surface has been floated, the blades are angled to suit the concrete and achieve the specified finish.
