Which step comes first in the sequence to finish a concrete slab?

The first step in finishing a concrete slab is the screeding process. During screeding, workers use a tool, often a long board or a screed bar, to level the surface of the freshly poured concrete and remove excess material. This step ensures that the concrete is uniformly distributed and at the correct height according to the desired specifications.

Screeding is crucial because it establishes a flat and even surface, which allows for proper finishing in subsequent steps. Achieving a level base is essential for the overall integrity of the slab, as it affects drainage, aesthetics, and the final quality of the concrete.

After the screeding is complete, other finishing processes like bullfloating, the final finish, and power troweling can occur, but they all rely on having a properly prepared base from the screeding stage.
