Parking Lot Striping at night or in the early morning hours is a tricky trade. Most of the time, parking lots are striped during the day. The parking lots are blocked to foot and vehicular traffic until the paint is dry. During the day, the painted lines usually dry much faster than at night or in the early morning. However, some parking lots just can’t afford to be closed during the day. If you can totally prevent all foot and vehicular traffic in a given area, there is no reason why you can’t stripe just about any time. Keep in mind, though, that no matter how little paint you apply, it will dry a lot slower than the same paint applied later in the day when the asphalt has had a chance to heat up. Consider these variables that affect the speed of paint drying on asphalt or concrete:
1. Sunlight/Shade 2. Wind 3. Heat in the pavement 4. Temperature 5. Relative Humidity 6. Moisture in the Asphalt
What to consider
In the very early morning and at night, you won’t have the assistance of the sun to warm the pavement. The heat that is stored in the asphalt helps facilitate the drying of the paint and the warm daytime temperatures also speed along the process. These are some of the things that give your paint the ability to dry quickly and avoid costly accidents. The biggest enemies of paint not drying are humidity, shade and cool air temperature. So be mindful of them!
