What is "scarifying" in the context of concrete finishing?

Scarifying in the context of concrete finishing refers specifically to the process of roughening a concrete surface. This technique involves using specialized equipment or tools, such as a scarifier or grinder, to remove a portion of the surface layer of the concrete. The purpose of scarifying is to prepare the surface for further treatments, enhance adhesion for overlays, or improve surface profile for better traction.

Scarifying is crucial in various applications, including resurfacing, coating, or repairing concrete, because it helps to create a surface that allows for better bonding with subsequent layers. A roughened surface can significantly increase the effectiveness of adhesives, sealers, or new concrete being applied on top.

In contrast, adding texture to concrete might involve more aesthetic purposes rather than preparing it for further work, while curing concrete pertains to techniques ensuring the concrete hardens properly over time. Mixing concrete ingredients focuses on the initial preparation of the concrete mix itself rather than finishing processes.
