Exterior foundation guide: keep air, surface and overnight temperatures between 10–30°C. Do not apply in wet conditions or with rain forecast within 24 hours. Allow 6–8 hours of drying in recommended conditions before fog or dew, and apply below 80% relative humidity. The guide states a 5-degree margin above dew point without identifying the unit; confirm that margin with the manufacturer. Allow the prepared concrete to dry completely and do not allow the coating to freeze before full cure. Cold or humid weather extends drying and curing. Follow the complete primer, coat-thickness and backfill instructions.

The manufacturer’s roof application guide includes Waterproof Sealant and specifies dry conditions between 10–30°C, including overnight temperatures; it does not separately label air and surface limits. No rain, fog or dew may be forecast within 24 hours. Apply below 80% relative humidity, out of hot, direct and intense sun. The guide says the surface must be at least 5 degrees above the environmental dew point without identifying the unit. Confirm that margin with the manufacturer. This guide is for flat/low-slope roofs; follow the guide for the intended project and coating system. The TDS’s 25°C cure test and −7°C low-temperature flexibility are not application limits.
