Water can be ponded, sprayed, or misted onto the surface. 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.
