Exterior project planning

Application conditionsManufacturer guidance
Air temperature
10°C to 30°C
Surface temperature
10°C to 30°C
Rain-free window
24 hours

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.

Manufacturer guidance Reviewed 2026-10-24 · CA

Check the air, the actual surface, overnight conditions and the full drying or curing period. The current product label takes precedence.

Exterior maintenance
Application method

a brush, roller, or single component sprayer to provide a seamless and fully adhered membrane to most substrates.

Drying time

At 25°C and 50% relative humidity, Liquid Rubber Foundation Sealant fully cures in 24-48 hours. Curing time increases in colder temperatures or higher humidity so environmental conditions must be considered before application.

Use the sheet for your exact product code and finish. Coverage and times depend on the stated temperature, humidity, substrate and coat thickness.
