How to Speed Up Concrete Drying | Hunker

Concrete is pliable as it dries, so it is preferable for it to dry quickly to avoid damage during the drying process. While you can speed up concrete drying only so much, there are ways of accelerating the process to a certain degree. Step 1 Pour the concrete during warmer, sunnier weather. It will dry faster than it would in cooler weather.
