Restriping

Restriping is the process of repainting or renewing road markings and parking-lot lines to restore visibility, update traffic control information, or adjust lane configurations. It is typically performed on highways, local streets, intersections, bike lanes, school zones, crosswalks, and parking facilities. The goal is to provide clearer guidance to drivers and pedestrians and to reflect changes in traffic patterns or regulations.

Common materials include water-based or solvent-based paints for shorter or mid-term markings, and longer-lasting options such as hot- or cold-applied thermoplastic and epoxy-based coatings. Thermoplastic materials, often combined with reflective glass beads, offer greater durability and nighttime visibility. Applications range from lane lines and centerlines to arrows, legends, symbols, and curb marking updates.

Planning and execution require adherence to local standards and permit processes. In many places, markings must conform to national or regional guidelines (for example, the MUTCD in the United States). Work typically involves traffic control plans, temporary lane closures, and precise layout of lines using specialized striping equipment. Weather, pavement condition, and traffic volume influence material choice and timing.

Lifespan varies by material and traffic. Cold-water-based paints may last months to a couple of years, while thermoplastics can endure several years with proper maintenance. Maintenance considerations include ensuring sharp, continuous lines, adequate reflectivity, and re-striping cycles aligned with wear patterns and regulatory updates. Restriping helps maintain safety and efficiency by restoring legibility of roadway and lot markings.
