Power trowels can be used for which finishing steps?

• A. Floating and troweling
• B. Floating only
• C. Troweling only
• D. Edge finishing

Answer: (A)

Power trowels are built to finish concrete surfaces efficiently by performing two key steps in one machine: floating and troweling. Floating brings the cream to the surface, fills small imperfections, and begins smoothing the slab. A power trowel, when used as a float (often called power floating), helps level and texture the surface on large areas. After floating, the same machine can be used to trowel, which densifies the surface and produces a smooth, hard finish. Edge finishing, however, usually requires hand tools because power trowels can’t reliably reach into corners and along edges. Finishing only by floating wouldn’t produce the dense, polished surface you get with a trowel pass, so combining both steps with a power trowel is the correct approach.
