Red Seal Concrete Finisher Practice Exam

What does "finishing" refer to in concrete work?

1. The process of mixing concrete

2. The process of applying paint to concrete

3. The process of smoothing and shaping the surface of cured concrete

4. The process of curing concrete

The correct answer is: The process of smoothing and shaping the surface of cured concrete

In concrete work, "finishing" specifically refers to the process of smoothing and shaping the surface of cured concrete. This step is crucial as it determines the final appearance and texture of the concrete surface, which can influence both aesthetic and functional qualities. Finishing techniques can include methods such as troweling, floating, or broom finishing, each giving the concrete a different texture and slip resistance based on the intended use of the surface. Achieving a high-quality finish involves careful attention to timing, as the concrete must be at the right stage of curing to be worked on effectively. This process can also enhance the durability and longevity of the concrete, as a well-finished surface can better resist weathering and wear over time. Other options misrepresent aspects of concrete work. Mixing concrete is a distinct and earlier phase in the overall process, while applying paint is not part of finishing but rather a separate task related to surface treatment. Curing, similarly, refers to the process of maintaining adequate moisture and temperature in fresh concrete to allow for proper hardening, not to the smoothing or shaping of the concrete surface.
