Warm air is essential for effective drying of wet flooring during the drying process due to its ability to hold more moisture than cooler air. When air is heated, its capacity to absorb and retain moisture increases, which is crucial when trying to remove water from materials like flooring. The warm air can facilitate evaporation, transferring moisture from the wet surfaces into the air, where it can be exhausted or removed.

In an ideal drying scenario, the combination of warmth and movement helps to continuously replace the moist air with drier air, enhancing the overall drying efficiency. Using cool air would slow down the drying process because cooler temperatures would lead to a lower moisture retention capacity. Humid air would not be helpful either, as its high moisture content could hinder effective moisture removal from the wet surfaces. Lastly, stagnant air does not promote evaporation; moving air is necessary to carry away the evaporated moisture, ensuring that the drying process continues effectively.
