Damaged coating often appears wrinkled, loose, and lifeless. Coatings can fail from moisture above or below if present before curing is largely complete. E las tek formulated some coatings differently in winter to enable them to dry more quickly and to be less water sensitive. Coatings will dry without problems if applied in suitable weather, if ponding areas are avoided, and adequate drying time allowed. Drying Time increases as temperatures fall and humidity rises.
Direct sun is very helpful in drying.
Overcast skies dramatically slow drying. Days are shorter in winter, allowing fewer hours of drying heat. Temperatures often drop rapidly when the sun sets. Condensation on roofs at night is common in cooler weather. This moisture must cause a delay in the application of coatings until the roof is dry the next day.
