True or False: Pan floats used on either walk-behind or riding machines improve levelness but not flatness.

True or False: Pan floats used on either walk-behind or riding machines improve levelness but not flatness.

• A. True
• B. False
• C. Depends on mix
• D. Cannot determine

Answer: (B)

Pan floats on walk-behind or riding machines are used to finish the concrete surface by smoothing the cream and filling small voids. This step doesn’t just address roughness; it also helps bring the surface to a more even plane and reduces short-range waviness. Levelness concerns long-distance straightness across the slab, while flatness concerns the smoothness and absence of bumps or ripples over shorter spots. By smoothing and consolidating the surface, pan floats improve both characteristics, not just levelness. That’s why the statement is false.
