How thick is applied runway paint?

Applied runway paint typically has a thickness ranging from 15 to 30 mils (0.015 to 0.030 inches) or about 0.38 to 0.76 millimeters. The exact thickness can vary based on the type of paint used and the specific requirements of the airport. The application process, including the number of coats, also influences the final thickness. Proper thickness is essential for visibility and durability under various weather conditions and heavy aircraft traffic.
