Winter Road Marking Paint: Key Application Considerations
Winter conditions pose unique challenges for road marking, requiring specialized materials and techniques to ensure durability and visibility. Here are critical precautions for optimal results:
Surface Preparation
Ensure pavement is completely dry and free of snow/ice. Use hot-air lances or gas torches to remove moisture, as residual water causes bubbling and adhesion failure.
Material Selection
Thermoplastic: Maintain temperature at 220°C to prevent rapid cooling and poor glass bead adhesion.
MMA Resin: Ideal for sub-zero temperatures (-15°C to 35°C), curing in 10–30 minutes with superior bonding strength.
Weather & Timing
Avoid施工during snowfall or below 5°C. Opt for midday (11:00–16:00) when temperatures are highest.
Application Adjustments
Increase glass bead dosage (≥400g/m²) for wet-weather reflectivity.
Apply thinner layers (0.4–0.6mm) to prevent cracking from thermal contraction.
Post-Application Care
Protect fresh markings for 4–6 hours of curing. Inspect for bubbles or cracks, indicating moisture contamination.
Pro Tip: Use fast-curing MMA resins for critical timelines, reducing downtime by 80% compared to epoxy.
