The American Concrete Institute recommends a maintained temperature of 70 degrees F for three days or 50 degrees F for five days to gain sufficient strength for a cold pour to perform up to specification.
The ideal temperature for applying water-based concrete stain is 70 degrees Fahrenheit. You can apply the stain in temperatures as low as 45 degrees, but lower temperatures can cause slower drying time. The temperature can be as high as 90 degrees for stain application, but higher temperatures can prevent the stain from penetrating the concrete well. Acid-Based Concrete Stains Acid-based concrete stain should be applied when the concrete temperature is between 59 and 70 degrees Fahrenheit. The staining process will experience similar issues to water-based stains if the temperature is too high or too low.
