How is the surface of newly placed concrete typically finished?

The surface of newly placed concrete is typically finished by moving a straightedge back and forth. This method, often referred to as "screeding," involves leveling the concrete to ensure a smooth and even surface. The straightedge is dragged across the surface of the freshly poured concrete, which helps to remove high spots and fill in low spots, resulting in a uniform surface that is important for both aesthetic and functional purposes.

This finishing process is crucial as it sets the foundation for subsequent finishing techniques, such as troweling or edging, which enhance both the appearance and durability of the concrete. It is particularly effective in larger areas where a hand-finish may not achieve consistent results. While other finishing methods can complement the overall finishing process, the use of a straightedge for initial leveling is a standard practice in concrete work.
