Detailed answer: Two core product categories are recommended: **First choice:** Nano-nylon checkerboard-type road marking paint. This is a "long-lasting rain-night road marking," with key advantages including excellent reflectivity in rainy conditions and the slowest decay rate. It also boasts superior hydrophobic properties (rainwater drains quickly, and the checkerboard-shaped structure floats on the surface), high wear resistance, high construction efficiency, and the best overall cost-effectiveness. Suitable for highways, urban expressways, bus lanes, and other scenarios with high safety requirements in rainy nights, it requires application with a large road marking vehicle. **Second choice:** Two-component structural road marking paint. This is also a "relatively long-lasting rain-night road marking," offering good reflectivity in rainy nights with slow decay, high wear resistance, and economical material usage. Suitable for all types of highways and urban roads, it is applied using dot-matrix or extrusion dot-matrix equipment. The checkerboard-shaped dots or irregular star-shaped dots allow for water drainage and anti-slip properties.

Detailed answer: For urban roads/ordinary highways: prioritize room temperature pure acrylic road marking paint (easy to apply, cost-effective) and two-component spray-on (flat line) paint (environmentally friendly, wear-resistant);
For highways/high-frequency road sections in rainy nights: choose nano nylon checkerboard pattern markings (long-lasting reflective and hydrophobic warning) and two-component star-shaped structure coatings (braking anti-skid and rainy night reflective).
Parking lot/residential road: Choose hot-melt road marking paint (fast drying, easy to apply, and stain resistant) and colored anti-slip pavement materials (bright colors, anti-slip and wear-resistant, available in red/gray/blue and other colors);
Sidewalks/bicycle lanes: Choose colored anti-slip pavement materials (lightweight, does not increase the burden on the roadbed, has strong anti-slip performance, and can be used in gardens, scenic areas, and schools).

Detailed answer: The following products all meet environmental protection requirements: Two-component series (star-shaped structure type, spray type, trowel type, etc.): No heating is required for application; the solvent fully participates in the chemical reaction, resulting in no VOC emissions; Water-based road marking paint: Contains no organic solvents, is harmless and pollution-free to humans during production and application, has extremely low VOC emissions, and strongly bonds glass beads for long-lasting reflectivity; Nano-nylon checkerboard-type marking paint: No abrasive dust, moderate noise level, dense structure prevents cracking and chipping, and is environmentally friendly.

Hot-melt vibration type: ≤5 minutes (20°C, 40% humidity), 7-8 kg/m² (thickness approx. 5 mm), UV resistant, anti-aging.

Detailed answer: Abrasion resistance ranking (from highest to lowest): Nano-nylon checkerboard markings > Two-component series (structural, scraping, star-shaped) > Hot-melt super-bright type > Room temperature pure acrylic > Ordinary hot-melt type; Weather resistance: Two-component series (chemical cross-linking curing, water-resistant, acid and alkali-resistant, UV-resistant), nano-nylon markings (high and low temperature resistant, aging-resistant), water-based coatings (abrasion-resistant, good weather resistance) are the best; Service life: Nano-nylon checkerboard type (longest, reduces repeated construction), two-component series (long-lasting, several years), hot-melt type (longer service life under normal conditions), room temperature type (high cost-effectiveness, service life superior to water-based).

Coating Type, Application Equipment, Application Method Nano Nylon Checkerboard Type: Large marking cart (e.g., WRD5260THX), ride-on marking machine; pump extrusion molding (regular checkerboard pattern) Two-Component Star-Shaped Structure Type: Two-component marking cart, ride-on marking machine, hand-push marking machine; continuous extrusion spray (marking cart), intermittent rod-throwing (hand-push machine) Two-Component Scraping Type: Dedicated scraping equipment (marking cart, ride-on marking cart); scrapes to form flat lines, square or ribbed vibrating lines Hot Melt Type (including vibrating type): Dedicated hot melt marking cart, ride-on marking machine; heated and melted, then extruded, with glass beads sprinkled on the surface Room Temperature Pure Acrylic/Water-Based Coatings: High-Pressure Airless Spraying Equipment; single coat or double coat (first coat dried before subsequent coats)

Detailed Answer: Reasons: High-brightness hot-melt road markings and irregularly shaped flat hot-melt road markings tend to have rapid reflectivity decay; uneven distribution of glass beads during construction; failure to use matching internal/surface mixed glass beads; insufficient attention to glass bead settling during construction; excessively high glass beads; and using excessively large particle sizes. The glass bead settling rate should be controlled (1/2-2/3); ensure the road surface is smooth during construction; the road is a busy section with heavy vehicle traffic, leading to significant wear and tear on the glass beads and reduced reflectivity. Solution: You can contact our after-sales team for professional guidance tailored to your specific situation.

Detailed Answer: Causes: Failure to use a dedicated primer during construction; inadequate cleaning of the road surface; peeling may be due to incorrect primer application (e.g., hot-melt type requires a primer coat), improper hardener ratio; large climate variations, significant day-night temperature differences; high ambient humidity; Solutions: 1. Cracking: If it is a scraping-applied product, contact after-sales service to assess whether it is caused by material characteristics. We recommend replacing it with a nano-nylon checkerboard type (dense structure without cracks) or a two-component extrusion type; localized cracks can be repaired by sanding and recoating; 2. Peeling: First, clean the affected area (remove dust and oil), reapply a dedicated primer (hot-melt type uses a primer coat, two-component type uses a matching primer), then recoat with the original paint; if the problem is with the hardener ratio, after-sales service can provide precise mixing guidance; 3. If your problem cannot be resolved, please contact after-sales service for consultation and answers;

Detailed Answer: Causes: Excessive application of glass microbeads easily leads to dust accumulation; applying markings before the primer is dry allows solvents to penetrate the uncured coating, causing contamination; premature opening of traffic before the markings are completely dry makes them susceptible to damage and contamination. Solutions: 1. Strictly control the quantity and particle size of glass microbeads during construction, ensuring even application and minimizing randomness; 2. It is best to delay the application of markings on newly paved asphalt roads, ensuring the markings are applied only after the primer solvent is completely dry, and opening the road to traffic only after the markings are completely dry; 3. Routine cleaning: Use a high-pressure water gun to rinse (avoid strong acid and alkali cleaners), utilizing the self-cleaning properties of nano-nylon or two-component products; 4. Severe contamination: Local sanding followed by recoating is recommended. Subsequent replacement with nano-nylon checkerboard-type markings (less prone to abrasion dust) or two-component structural markings (strong stain resistance); 5. Dedicated cleaning solutions and recoating technical support are available after-sales.

Detailed Answer: Different methods for removing road markings: 1. Two-component scraping type old road markings: It is recommended to use TianTu high-pressure water removal truck (special equipment supplied by the group) to avoid damaging the road surface; 2. Hot-melt type old road markings: High-pressure water can be used for removal or a special hot-melt road marking removal machine, along with a thinner to clean the residue; After-sales support: We can provide removal equipment rental/recommendation services, or arrange a professional construction team to assist with removal.

Detailed Answer: Equipment Cleaning: After applying solvent-based or two-component paints, clean the marking equipment with the matching thinner (composed of benzene and esters, with good compatibility) to prevent paint hardening and clogging. For water-based paints, simply rinse with water. Thinner Usage: Used only to adjust the viscosity of solvent-based paints (adjust according to road surface roughness during application; do not use excessively). When cleaning equipment, apply directly to areas with residual paint, wipe clean, and then rinse with water. Precautions: Keep thinner away from heat sources and open flames; store in a well-ventilated area. Dosage and operation instructions can be provided by after-sales service.
