Question: 1 / 400

Why is timing critical when finishing concrete?

To maximize evaporation of water

To prevent overworking the concrete

To ensure the surface is finished before it hardens too much

Timing is critical when finishing concrete primarily because it ensures that the surface is completed before the concrete sets and hardens excessively. The finishing process involves techniques like troweling and smoothing that require the concrete to be at a workable consistency. If finishing is delayed past the appropriate time, the surface may become too stiff to manipulate effectively, leading to issues such as insufficient smoothness, inability to remove imperfections, or even cracking as the concrete continues to cure without proper finishing.

In this context, being timely allows the finisher to achieve the desired surface characteristics, such as texture and strength, while the concrete is still pliable. Once it hardens beyond a certain point, the opportunity to achieve these results diminishes significantly, making it crucial to manage timing accurately during the finishing stage.
