How long does it take for a Concrete Slab or Floor to dry?

No exact period can be specified for the drying of such floors to reach acceptable moisture content, as this is affected by temperature and humidity within the building as well as concrete curing times and other factors. Typically a period of 1 month per inch (25mm) depth of concrete or sand/cement screed is often quoted. Longer periods may be required in areas of high humidity or low temperature. During the drying period and prior to applying the floor covering, the floor should be regularly checked to monitor moisture content.
