Common Road Marking Paint Problems and Solutions

Road markings play a vital role in traffic safety, but improper application or poor-quality materials can lead to early failure. Understanding the common problems and their solutions can help improve durability and reduce maintenance costs.

1. Paint Peeling

Possible Causes

• Dirty or wet pavement

• Poor surface preparation

• Low application temperature

• Heavy traffic before the paint has cured

Solution

Clean and dry the road surface before application, follow the recommended construction temperature, and allow sufficient curing time before reopening the road.

2. Cracking

Possible Causes

• Excessive paint thickness

• Overheating during melting

• Poor-quality resin

Solution

Maintain the proper coating thickness and apply thermoplastic road marking paint at the recommended temperature of 180–220°C.

3. Poor Night Visibility

Possible Causes

• Low-quality reflective glass beads

• Uneven glass bead distribution

• Incorrect application method

Solution

Use high-quality road marking glass beads and ensure they are evenly distributed to achieve reliable retroreflectivity.

4. Color Fading

Possible Causes

• Strong UV exposure

• Inferior pigments

• Heavy traffic wear

Solution

Choose weather-resistant thermoplastic road marking paint designed for long-term outdoor performance.

Conclusion

High-quality road markings depend on both premium materials and correct application methods. Proper surface preparation, suitable construction temperatures, and the use of reliable thermoplastic road marking paint and reflective glass beads can significantly improve service life and road safety.

Whether for highways, parking lots, airports, or urban roads, selecting the right road marking system helps reduce maintenance costs while ensuring long-lasting visibility.
