Highway Restriping: Gas Airless Paint Sprayer & Fast-Drying Road Paint

1. Project Overview

120 km highway lane marking restoration project. Tight traffic control required all striping work to be completed during brief 4-hour night-shift windows without external power supply.

2. Challenges

No Jobsite Power: Total absence of roadside electricity required independent self-powered equipment.

Severe Penalties: Exceeding the 4-hour lane closure limit incurred heavy hourly fines.

High Viscosity & Uneven Surface: Conventional cold sprayers suffered from line bleeding and uneven thickness on aged asphalt.

3.  Zhongren Solution

ZR-G Gas Airless Sprayer: Powered by a commercial-grade petrol engine, delivering a stable 3,300 PSI (227 bar) and 8.5 L/min flow rate with zero reliance on generators.

Dual-Gun Sync Striping: Simultaneous spray of solid and skip lines in a single pass with clean, razor-sharp edges.

Quick-Drying Acrylic Paint: Specially formulated for fast curing, achieving complete tire-tracking

4.  Key Results

35% Faster Completion: Striping speed reached 4.2 km/h, finishing all shifts well ahead of schedule.

Fast Traffic Reopening: Lanes reopened 20 minutes post-application without paint pickup.

Superior Film Quality: Uniform 350–400 μm wet film thickness passed municipal inspection on the first run.
