Typical concrete takes 28 days (4 weeks) to cure. Prior to the 28 days concrete still has moisture in it that weakens the strength of the concrete.

Keep New Concrete Moist For Best Cure Concrete continues to gain strength after pouring for as long as it retains moisture, but the longer it moist-cures, the slower the rate of strength gain. Moist-curing concrete for 20 days more than doubles its strength compared to four days of moist-curing, which is considered a minimum. Although the greatest gain is in the first week or two after pouring, the curing process continues for several months.

How Long to Wait to Paint New Exterior Concrete? Too much moisture in new concrete can cause paint to bubble. It usually takes at least 30 days for moisture to dissipate enough for paint to adhere. You can test for moisture by taping a piece of foil to the surface, sealing all the edges with tape, and checking for condensation after 24 hours. If there is no condensation, the concrete is dry enough for painting. High alkaline levels also can stop paint from sticking to the concrete. It can take anywhere from 30 to 90 days for alkaline levels to drop enough for painting. Test the pH, and look for levels 9.0 and 10.0. If it is higher, the concrete needs to cure longer.
