Putty Spraying Robot (6.2m)
Putty Spraying Robot (6.2m)
6.2 m Spraying Height | 1 Robot + 2 Operators | Up to 2,000 m²/Day
One robot for both putty spraying and latex paint spraying—just switch materials.
Suitable for interior wall paint and putty spraying in public buildings, including factories, hotels, schools, hospitals, and other large-scale public and commercial buildings on the same robotic platform.
One robot works with two operators: one operates the robot while the other performs putty scraping. This collaborative approach improves labor utilization and maintains a smooth wall finishing workflow throughout the project.
The 6M2 robot delivers more consistent wall finishing quality than traditional manual application, with over 95% putty spraying coverage. Daily productivity reaches 1,000–1,200 m² for the first coat and 1,600–2,000 m² for the second coat.
Factory buildings typically feature high interior walls, large uninterrupted wall areas, and fast-paced construction schedules. This putty & painting spraying robot is designed for these environments, supporting both putty spraying and latex paint spraying by simply switching materials. It helps contractors improve productivity, reduce repetitive manual work, and maintain consistent wall finishing quality across large industrial spaces.
Hospitals require clean, consistent wall finishes across extensive corridors, wards, and public areas, often within tight construction timelines. This interior wall painting robot delivers stable spraying quality throughout different wall finishing stages, allowing contractors to efficiently complete both putty spraying and latex paint spraying while improving consistency on large interior projects.
Educational buildings often include gymnasiums, auditoriums, and other high-ceiling interior spaces where manual wall finishing is time-consuming and labor-intensive. With a maximum spraying height of 6.2 meters, the robot efficiently covers tall walls while supporting both putty spraying and latex paint spraying on the same robotic platform.
Hotels and commercial buildings require consistent wall finishes across large numbers of guest rooms, corridors, lobbies, and public spaces, while meeting strict project deadlines. By switching spraying materials, one robot supports both putty spraying and latex paint spraying, helping contractors improve efficiency, reduce equipment investment, and deliver uniform finishing quality throughout the project.
The industry-leading ultra-compact body, measuring less than 800 mm on each side, is equipped with a proprietary omnidirectional mobility platform that delivers zero-turn-radius maneuverability. The robot moves easily through narrow corridors in internationally standardized building spaces, including elevators, and confined indoor construction areas, allowing seamless access to different work zones on large projects.
The innovative Telescopic outrigger design automatically adapts to different working conditions: Stays compact in retracted mode for efficient passage through tight spaces; when deployed, it forms a four-point stable base to ensure safety during high-altitude spraying.
Designed for demanding construction environments, the robot operates for up to 8 hours of continuous operation on a single charge—sufficient for full-day high-intensity tasks, supporting continuous wall finishing throughout a full working shift.
The dedicated high-efficiency putty mixer adopts a "one-grind, dual-filter" process to ensure putty material is smooth and free of particles. Stable material preparation helps improve spraying consistency, reduces equipment downtime, and supports reliable performance during large-scale wall finishing projects.
Built-in patented progressive filtration system performs three-stage purification before spraying, effectively eliminating impurities for a clean and consistent spray finish.
The robot utilizes high-pressure airless spray technology to improve coating transfer efficiency and reduce material loss during application. Compared to traditional air-assisted methods, it minimizes overspray and supports higher-viscosity materials with lower dilution requirements, ensuring more effective material coverage on wall surfaces.
Delivers smooth and consistent coat. The first coat of putty is applied at 1.2–1.5 mm thickness, and the second coat at 0.6–0.9 mm—surpassing manual work quality and outperforming comparable products in the industry.
With the industry’s most compact body (single side < 800 mm) and a self-developed omnidirectional chassis, the robot easily enters narrow spaces and adapts to complex construction environments.
Combined with a 6-DOF robotic arm, intelligent lift system, and AI-powered algorithms, it accurately simulates human motions, enabling seamless automated spraying on walls, ceilings, inside/outside corners, beams, and more—ensuring complete, dead-zone-free coverage.
Spraying efficiency is outstanding:
First coat: 1,000–1,200 m²/day
Second coat: 1,600–2,000 m²/day
Equipped with both active and passive safety systems, the robot performs real-time monitoring throughout operation to ensure zero safety incidents. Since entering the market, it has maintained a 100% accident-free record.
Tablet-based one-click control with an intuitive visual UI —no programming skills required. Ordinary workers can independently run the robot after basic training. Built-in standardized spraying presets enable quick job start and eliminate manual parameter tuning errors, greatly lowering the usage threshold.
The robot delivers stable and reliable performance, backed by a professional technical team that ensures fast response and comprehensive support throughout the product’s lifecycle.
