Reflective marking paint is critical for road safety, but its fade over time compromises visibility. Understanding the causes and preventive measures ensures long-lasting performance.
Causes of Fading
UV Exposure: Sunlight degrades pigments and binders in reflective marking paint, especially in high-traffic areas.
Poor Adhesion: Inadequate surface preparation or low-quality primers reduce paint adherence, accelerating wear.
Environmental Pollutants: Acid rain, chemicals, and abrasion from traffic erode the paint layer and embedded glass beads.
Inferior Materials: Cheap reflective marking paint lacks UV-resistant pigments or durable resins, fading faster.
Prevention Tips
Use High-Quality Paint: Opt for reflective marking paint with UV inhibitors and premium glass beads for better reflectivity retention.
Proper Application: Clean surfaces thoroughly, apply primer, and ensure even glass bead distribution during installation.
Regular Maintenance: Inspect and touch up faded sections annually to maintain retroreflectivity standards.
By addressing these factors, reflective marking paint can retain its effectiveness for years, enhancing nighttime road safety.
