At What temperature can silicone caulk be applied?

Phelps Silicone Sealants can be applied in a temperature range of -25°F to 120°F. However, for best application results the caulk itself should be at room temperature. Regardless of temperature, it is important to ensure the surface be clean, dry, free of frost (for cold weather applications) for proper adherence to occur.
