Concrete finishing incorporates a variety of tasks that transform newly placed concrete from a rough, open surface to its final smooth state. The finishing process is the concrete craftworker’s opportunity to determine the final appearance of the concrete, as well as its surface density and other characteristics. If the finishing is poorly done, all the best mixing and placing efforts that preceded it, and all the curing efforts that follow it, will not be able to salvage the undesirable result. A concrete finisher plays a key role in how the surface looks, feels, and performs. It is this phase of the work where skills, practice, and experience really pay off.
