Flooring, tiling, or painting on a concrete surface that is insufficiently dry can end up being a disaster. An experimental project recently used IoT sensors and AI to determine when it is safe to start finishing concrete surfaces.
Haste and Imperfect Conditions Lead to Failure
To successfully first cure and then dry concrete requires specific conditions. You need to maintain a temperature higher than 10°C and a relative humidity of greater than 80 percent in the concrete.
Once the concrete is hardened, you have to make sure that it is dry enough for finishing. Typically, the relative humidity should not exceed 82 percent. Some flooring materials require a humidity of less than 75 percent for successful application.
