What does a screed establish on a slab?

Explanation:
Screeding sets the surface to its final elevation and drainage direction. After the concrete is placed, the screed bar or straightedge is pulled across the top to strike off excess and bring the slab to the planned height. This establishes the final grade—the surface level relative to the forms—and the slope, which guides water to drain away rather than ponding on the slab. Getting the right slope is crucial for drainage and long-term performance. Color, finishing time, and texture are determined by other factors and later steps, not by the screed.
