Missing the window of finish ability can lead to surface defects and failure to achieve what?

• A. The specified flatness or surface finish
• B. Earlier strength
• C. Longer curing time
• D. Increased staining

Answer: (A)

Finishability is the window after concrete placement when the surface can still be smoothed and brought to the required level and texture. If you miss that window, the mix begins to stiffen and set, making it much harder to produce a smooth, uniform surface. As a result, you’re likely to see defects such as waviness, ridges, or irregular texture that don’t meet the specified flatness or surface finish. The goal of finishing is to achieve the exact surface quality called for in the specs, so missing the finish window directly undermines that requirement.
