What tool is used immediately after screeding to smooth the surface?

• A. Bull float
• B. Darby
• C. Magnesium float
• D. Hand float

Answer: (A)

After screeding, the surface is still plastic and ridges need to be leveled without pulling out too much cement paste. The bull float is used first because its wide, flat blade smooths the surface efficiently, compressing the surface and bringing the cream to the top. This step fills small voids, levels high spots, and leaves a uniform, workable surface for the next finishing passes. Magnesium or hand floats come a bit later for finer smoothing once the bleed water has diminished, and a darby is used after the initial float to further flatten ridges and bring the surface to level. So the immediate smoothing after screed is done with the bull float.
