Which step should follow screeding in a typical finishing sequence?

• A. Placing
• B. Edging
• C. Bull floating
• D. Finishing

Answer: (C)

After the screed pass, the surface needs to be smoothed and consolidated before any finishing passes. Bull floating accomplishes this by using a wide, flat blade to smooth out ridges, fill small surface voids, and push the fine cement paste (cream) up to the top. This creates a more uniform, stable top surface and reduces excess laitance, making the slab ready for edging and the final finishing passes. Placing occurs earlier in the process, and finishing (troweling) comes after the surface has been bull floated and has stiffened enough to accept a higher-quality finish, so the next immediate step is bull floating.
