Which step in finishing concrete is aimed at leveling large gaps and removing high spots?

Screeding is the process in concrete finishing that specifically focuses on leveling the surface, addressing large gaps, and removing high spots. During this step, a straightedge or screed board is used to drag over the freshly placed concrete, effectively leveling it by filling in low spots and cutting off the excess material from high spots. This ensures a uniform and smooth surface that is critical for the subsequent finishing processes.

Edging typically involves shaping the edges of the slab to create a finished look and prevent chipping, but it does not address the leveling of the main surface. Floating is a later step that helps to further smooth and consolidate the surface after screeding, but it does not focus on correcting larger discrepancies in elevation. Jointing is used to create controlled cracks in the concrete, which helps manage shrinkage but does not contribute to leveling the surface itself. Understanding the purpose and sequence of these steps is crucial for achieving a high-quality concrete finish.
