How does a power trowel work and when should it be used?

A power trowel is a machine used for polishing and smoothing finished concrete surfaces, leaving the pavement with a perfect and fine finish. Power trowels use blades or rotors to smooth and polish the concrete with a rotating motion. The blades are typically shielded by one or more rings, providing added safety when operating the machine while working directly on the concrete surface.

If the task involves a large surface area, such as a road or an industrial warehouse floor, it´s advisable to use a power trowel to smooth and polish the surface effectively.
