True or False: Float blades for power troweling machines are wider than trowel blades and turned up on the edges to prevent them from digging into the surface.

• A. True
• B. False
• C. Sometimes
• D. Not applicable

Answer: (A)

Float blades are the finishing tools used during floating to smooth the surface and bring the cream to the top. They are designed to cover more area, so they’re wider than trowel blades. The edges are turned up to skim over the surface rather than cut into it, which helps prevent gouging as the machine spins and keeps the finish even while the concrete is still relatively soft. Trowel blades, by contrast, are narrower and sharper for firming and closing the surface. So the statement is true.
