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.
Minimum floor temperature for coating is 55Â°F (13Â°C). Product should be applied when ambient/air temperature is 60-85Â°F (16-29Â°C). Concrete floors take a long time to warm up; make sure the previous day has also been at least 60Â°F (16Â°C) prior to coating. Do not apply if night time temperature is expected to drop below a low of 65Â°F (18Â°C). For best results, temperatures should not drop below 65Â°F (18Â°C) for 24-48 hours after applying the coating.
