Concrete Slab Power Float Finish

It is generally not appropriate for external paving.

Concrete slab power float finish.

At cfs we usually perform this task after your purchased concrete has partially set and has been leveled and tamped. However timing is crucial and if power floating is undertaken too early bleed water may be worked into the surface thereby weakening it and leading to the risk of surface delamination. Finishing a concrete slab with a power trowel. Power floating eliminates the time and materials needed to apply a finishing screed and is quicker and less labour intensive process than hand trowelling.

Therefore before beginning the power floating process the concrete must be left to partially set having been levelled and tamped. Trowelled finishes trowelling follows floating to provide a direct finished wearing surface. A power float is a hand operated machine used to produce a smooth dense and level surface finish to insitu concrete beds. When carried out correctly on concrete of the appropriate class trowelling leaves a smooth very dense surface.

Concrete finishing is performed after floating and it produces a dense smooth hard surface. Power trowelling of air entrained concretes is not recommended due to the risk of surface delamination. Power floated concrete offers the best option for smoothing large concrete slabs and getting the slab to a hard level finish. You may need to do two or more passes.

A power float is a machine used by hand either with the operator walking behind it or riding on a larger one if the project requires it in order to produce a smooth dense and level finish to a newly laid onsite poured concrete floor. Power floating concrete too early while it is too wet can cause delamination of the material basically it will tear it up.
