The dry time for your striping job varies according to which materials you use. (Learn more about the different types of striping materials here.) However, let’s assume you’re using waterborne paint:
Paint is normally drivable after one hour – in a hot summer day in the sun it’s dry to the touch in under 60 seconds.
Lines are totally cured in about four hours, depending on weather conditions
Colder weather and lack of direct sunlight can lengthen dry time
In colder weather, solvent based traffic paint is recommended
Whenever we talk about “normal” or “typical” conditions, we’re thinking about temperatures over 50 degrees Fahrenheit.
