How long until you can paint concrete? Curing New Concrete
Allowing the new concrete to cure for at least 30 days can reduce the alkalinity and moisture content to levels low enough for the concrete to take paint. But it can take as long as 90 days before new concrete has cured enough for painting, depending on climate and weather.
How long before you can paint fresh concrete? 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.
What happens if you paint concrete before it cures? Any paint or stain applied to young concrete while it’s still hardening can be negatively affected by residual moisture or the changing chemical content in the concrete. It takes about a month for all of the water to get used up in the hydration process.
How do you know if concrete is dry enough to paint? Moisture will prevent the primer and paint from adhering properly. An easy way to tell whether the floor is dry enough is to place a small piece of kitchen plastic wrap (about 12” square) to the surface of the concrete floor. Seal all edges with tape. Wait overnight and then check the plastic.

Should you wet concrete while curing?
ANSWER: Keeping concrete moist helps the curing process. If too much water is lost from the concrete through evaporation, the hardening process slows down or ceases. 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.
