What primary question should restorers ask regarding the condition of concrete?

The primary question restorers should ask regarding the condition of concrete is whether the concrete is sealed. This is crucial for a few reasons. A sealed concrete surface affects how water interacts with it during the drying process. If the concrete is not sealed, it can absorb moisture more easily, which could lead to longer drying times and potential structural issues. Additionally, understanding whether the concrete is sealed can inform the choice of drying techniques and equipment. For example, if the surface is sealed, restorers might need to employ different strategies than they would for unsealed concrete, like focusing on moisture removal from the surface rather than penetration into the material.

Considering the other options, the best finishing method, the thickness of the concrete, and the pouring temperature, while they may hold relevance in certain contexts, do not directly address the immediate concerns of moisture management in restoration efforts. Sealing primarily influences the interaction with water, which is essential in the drying process that restorers must manage efficiently.
