What are the visual signs of incomplete finishing on concrete?

• A. Flaking surface and discoloration
• B. Uneven surface, trowel marks, or excessive texture
• C. Cracking and settling
• D. Chipping and scaling

Answer: (B)

The visual signs of incomplete finishing on concrete primarily manifest as an uneven surface, visible trowel marks, or excessive texture. When finishing is done properly, the surface should be level and smooth, indicating that the finishing process was adequately completed. However, if the finishing is incomplete, it often results in variations in flatness, leading to an uneven surface. Trowel marks can occur due to insufficient final passes with the float or trowel, while excessive texture might suggest that the concrete was not sufficiently worked to achieve a desirable finish. All of these signs reflect a lack of attention to detail during the finishing process, which is crucial in achieving a high-quality surface on concrete flatwork. Proper finishing techniques are essential not just for aesthetic reasons but also for ensuring the durability and longevity of the concrete surface.
