Things to Know About Parking Lot Striping

  • Striping is important for two main reasons – aesthetics and safety.
  • Striping over fresh asphalt or sealer requires a water-borne coating, while striping over concrete substrates requires chlorinated rubber paint for optimal adherence.  Oftentimes, set-fast acrylic waterborne is the best paint to use for re-striping; however, it must be applied at temperatures above 45 degrees Fahrenheit.
  • Paint should be applied using an airless striping machine at a minimum of 13 mil wet film thickness to ensure high-quality lot marking.
  • Although some of the paint will soak into new pavement causing a thinner look, it is best to apply two thin coats rather than one thick one – too much acrylic latex paint can damage the pavement when the paint film shrinks.
  • Typical drying time is 30 minutes; however, traffic should remain off the lot for at least one full hour.
  • Re-striping should occur on your parking lot every two years, or when the remaining coating has been visibly reduced to 75% of its original appearance.
  • Before performing any lot marking procedure, be sure and verify that your parking lots are compliant with the Americans with Disabilities Act (ADA) standards.  For example, your properties must contain a minimum number of accessible stalls based on the size of the parking lot.  If your property does not meet these guidelines, reconfigure the appropriate number of spaces by repainting stripes or lay out new markings.
