Application Tips for Two-Component Road Marking Paint
Two-component road marking paint is widely used on highways, intersections, and industrial zones because of its durability and strong adhesion. Since it cures through a chemical reaction between the base material and hardener, correct application is essential for long-lasting performance. The following practical tips can help ensure reliable results.
1. Prepare the Surface Properly
Clean, dry pavement is critical. Remove dust, oil, loose particles, and old flaking markings before application. Moisture can interfere with curing, so avoid working on damp surfaces or during rain.
2. Follow Accurate Mixing Ratios
Two-component systems rely on precise proportions of base and hardener. Always follow the manufacturer’s recommended mixing ratio. Inaccurate mixing may cause incomplete curing, reduced strength, or premature failure.
3. Control Temperature and Weather Conditions
Most two-component paints perform best within a specified temperature range. Extremely low temperatures can slow curing, while very high temperatures may shorten working time. Check both air and pavement temperatures before starting.
4. Use Proper Equipment
Specialized spray or extrusion equipment ensures uniform thickness and consistent mixing during application. Calibrate machines regularly to maintain correct output and line dimensions.
5. Apply at Recommended Thickness
Film thickness affects durability and retroreflectivity. Applying too thin may reduce lifespan, while excessive thickness can lead to cracking or uneven curing.
6. Add Reflective Glass Beads Correctly
For night visibility, apply glass beads evenly while the coating is still wet. Proper embedment improves reflectivity and long-term performance.
Careful preparation, accurate mixing, and attention to environmental conditions can significantly extend the service life of two-component road markings, improving both safety and maintenance efficiency.
