If the concrete surface requires frequent cleaning, or the concrete surface is to be used as flooring, it shall have a ______ finish.

• A. Smooth
• B. Rough
• C. Textured
• D. Polished

Answer: (A)

When a concrete surface will be cleaned frequently or used as flooring, it should be finished smooth. A smooth finish creates a dense, low-porosity surface that’s easy to wipe, mop, and disinfect, with fewer crevices for dirt, oils, and moisture to cling to. Rough or textured finishes tend to trap dirt and moisture, making cleaning much harder and more labor-intensive. Polished floors can also be very smooth but involve a different finishing process and may not be the intended standard in every scenario. The smooth finish provides practical cleanability and durability for surfaces that see regular maintenance or foot traffic.
