Parking Lot Striping at night in the early morning hours is a tricky trade.
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. Just keep in mind 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 a chance to heat up. Consider these variables that affect the speed of paint drying on asphalt or concrete:
3. Heat in the pavement
5. Relative Humidity
6. Moisture in the Asphalt
In the very early a.m., you probably won’t have the assistance of:
2. Heat in the pavement
3. Warm temperature
these are some of the things that give your paint the ability to dry quickly and avoid costly accidents.
The time span between application and the point at which it will not cause “tracking” may be as short as 15 minutes to several days. Depending on the weather and the product used you may get very different results. The biggest enemies of paint not drying are humidity, shade and cool air temperature. So be mindful of them! One thing that we practice at Trueline Striping is to use rapid dry paint products. We use these in times when we feel there is a drying risk. Also make sure to carefully block off areas that do remain wet so nobody can wonder in to those areas. One slip can mean BIG problems for you.
Good Luck and happy Line Painting!
