Which step in the finishing sequence most directly reduces small surface imperfections before the final trowel pass?

• A. Edge and joint work
• B. Screeding
• C. Floating (and darby) to level and smooth the surface
• D. Curing

Answer: (C)

Floating to level and smooth the surface is the step that most directly reduces small surface imperfections before the final trowel pass. Using a float pushes the surface paste and fills tiny voids, knocking down minor ridges left from screeding and bringing the cream up to the surface so the texture becomes more uniform. The longer float (darby) that follows helps level and smooth across larger areas, further smoothing out slight highs and lows. This creates a consistent plane ready for the final trowel, which then hones the surface to a dense, glassy finish. Edge and joint work focuses on joints and edges, not the overall micro-surface texture; screeding establishes rough level early, and curing comes after finishing to control moisture, not to improve surface texture before the last pass.
