What is the primary benefit of broom finishing in concrete work?

The primary benefit of broom finishing in concrete work is that it increases slip resistance. When a broom finish is applied to the surface of concrete, the brushing creates grooves and textures that help improve traction. This is particularly important in areas where water may accumulate, such as sidewalks, driveways, and pool decks, as the enhanced surface texture reduces the likelihood of slipping, making these areas safer to walk on.

While improving appearance is a consideration in broom finishing, the primary focus is on functionality and safety. Enhancing curing time is not associated with broom finishing; this process does not directly affect how quickly the concrete sets or cures. Additionally, broom finishing does not impact the weight of the concrete, as it merely modifies the surface finish without altering the material's mass or density. Thus, the primary outcome of broom finishing is to improve slip resistance, making it an essential practice in ensuring the safety of concrete surfaces.
