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.

How often should you water new concrete?

One of the most common methods for curing concrete is to hose it down frequently with water—five to 10 times per day, or as often as you can—for the first seven days. Known as “moist curing,” this allows the moisture in the concrete to evaporate slowly.

How do you speed up concrete curing?

Tips on How to Speed Up Concrete Drying Time:

  1. Use the correct amount of water in the mix. Too much water can increase the drying time.
  2. Do not over-trowel or seal the surface.
  3. Keep doors and windows closed, the HVAC running, and fans circulating the air.
  4. You can also use dehumidifiers to remove moisture from the air.
