The hardening of concrete is a chemical reaction that requires certain conditions and temperatures. Ideally, concrete should be poured when the air temperature is between 50 and 90 degrees Fahrenheit. Cold temperatures slow the concrete-setting process, and when temperatures dip below freezing, the delay allows the water in the mix to freeze before the concrete hardens. This creates cracks in the concrete because water expands as it freezes.
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.
