A concrete slab should be bull floated as soon as possible after what procedure?

Bull floating is a crucial step in the process of preparing concrete after it has been poured. This operation involves using a long-handled tool to smooth and level the surface before any finishing work takes place. The correct point to begin bull floating is immediately following the screeding process.

Screeding is the action of leveling the concrete after it has been placed, ensuring that it is uniformly distributed and reaches the desired height. Once the screeding has been completed, the surface of the concrete is still wet and pliable, making it the ideal moment to use the bull float. This tool helps to eliminate any imperfections, fill in low spots, and bring the cream (moisture and fine particles) to the surface, which is vital for achieving an even finish.

If bull floating is delayed until after curing or finishing, the concrete may harden enough that the float cannot effectively work the surface. Thus, the timing immediately after screeding is critical for achieving the best results in the flatwork process.
