Also, Do you have to 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.Sep 2, 1990
How long does concrete take to dry before rain?
If the concrete is still fresh (around 2-4 hours after pouring), it’s important to cover the surface to protect it. However, once the concrete has been finished (between 4-8 hours after pouring), and has set hard enough for walking on, the effects of rain should be minimal.

How soon should I water concrete after pouring?
To keep it wet, many concrete contractors use burlap to soak up the water. How long to keep it wet depends on temperature and the mix—you want it to have reached sufficient strength on the surface. Typically, about 7 days is sufficient with Type I cement—less in warm weather.
Is watering concrete necessary?
ANSWER: Keeping concrete moist helps the curing process. Concrete hardens as a result of a chemical reaction, called hydration, between cement and water, not because it dries. The hardening, or curing, continues as long as moisture remains in the concrete.Sep 2, 1990
