Putty Spraying Robot (3.3m)
Putty Spraying Robot (3.3m)
95%+ Putty Coverage | Up to 1,000 m²/Day | 1 Robot + 2 Operators
Combines automated putty spraying and latex paint spraying into a single workflow
Designed for interior wall paint and putty spraying in residential buildings, apartments, hotels, office buildings, and other large-scale construction projects, the house painting robot streamlines the process with consistent quality.
One robot works with two operators: one operator controls the robot while another completes putty scraping and surface finishing, allowing spraying and manual finishing to proceed simultaneously.
The robot delivers finishing quality that surpasses traditional manual methods, with putty spraying coverage exceeding 95%. Daily productivity reaches 500–600 m² for the first coat and 800–1,000 m² for the second coat, helping contractors complete large-scale wall preparation more efficiently.

New residential developments, apartment complexes, affordable housing, and multi-building communities require wall preparation and finishing across hundreds of units. By supporting both putty spraying and latex paint spraying on one platform, this Legend Robot putty spraying robot helps contractors standardize wall quality, reduce labor dependency, and accelerate project delivery throughout large-scale residential construction.
Hotels, serviced apartments, student dormitories, rental housing, and other multi-unit buildings involve repetitive wall finishing across rooms with nearly identical layouts. This Legend Robot putty coating robot automates both putty spraying and latex paint spraying, allowing contractors to complete repetitive interior wall finishing more efficiently while maintaining consistent surface quality from room to room.
Office buildings, shopping malls, healthcare facilities, educational institutions, and mixed-use developments often require extensive interior wall finishing within demanding construction schedules. By completing both putty and latex paint spraying with one robotic system, this Legend Robot autonomous wall finishing robot improves labor utilization, shortens construction timelines, and delivers consistent wall finishing quality across large commercial spaces.
Existing residential, commercial, hospitality, and public buildings frequently require damaged wall surfaces to be repaired before applying new finishes. This Legend Robot wall finishing robot streamlines wall refurbishment by combining automated putty spraying with latex paint spraying, helping contractors restore interior walls more efficiently while reducing manual workload and ensuring a uniform finished appearance.
Instead of repeatedly stopping to reposition before each spraying cycle, Legend Robot’s pioneering mobile spraying technology enables its advanced construction painting robot to spray while moving, enabling uninterrupted putty application across large wall surfaces. This continuous operation improves spraying efficiency by 1.5–2× compared to traditional stop-and-spray methods, making large-scale putty application faster and more productive.
With the most compact body—measuring under 800mm in both length and width—the automatic spary painting wall robot meets global construction site access standards. Featuring a proprietary omnidirectional chassis with zero turning radius, it easily navigates narrow spaces like apartment entrances, narrow corridors, elevators, and other confined construction spaces without additional disassembly or transport equipment for 100% site accessibility.
Equipped with a dedicated putty mixer, the spray paint robot ensures fine and consistent putty texture through one grinding and two-stage filtration, significantly reducing the robot's failure rate. It can prepare 60L of putty within 5 minutes—enough to supply two robots simultaneously—delivering outstanding production efficiency.
The spray painting robot features an integrated putty filtration system. Before spraying, putty passes through an integrated three-stage filtration system that removes coarse particles and impurities. This significantly reduces nozzle clogging and mechanical failures, ensuring stable material flow and reliable spraying performance throughout long-duration wall finishing projects.
The spraying robot adopts high-pressure airless spray technology to improve coating transfer efficiency and reduce material waste during continuous wall finishing. Compared to conventional spraying methods, it minimizes overspray while supporting higher-viscosity putty and paint materials with lower dilution requirements, ensuring more effective material coverage.
The first coat of putty is sprayed at a thickness of 1.2–1.5 mm, and the second coat at 0.6–0.9 mm. Spraying thickness is precisely controlled, ensuring high flatness and a smooth, even finish.
With the industry’s most compact body and a proprietary omnidirectional chassis featuring zero turning radius, gap-crossing, ramp climbing, and obstacle negotiation, the robot easily navigates narrow and complex spaces for broad site accessibility.
Equipped with a 6-DOF robotic arm, lifting mechanism, and mature spraying algorithms, it flexibly adjusts spray angles to simulate human motion—delivering fully automatic, blind-spot-free spraying of walls, ceilings, and corners.
Powered by Legend Robot’s pioneering mobile spraying technology, our reliable system surpasses the efficiency limits of traditional stationary methods, enabling smooth and highly efficient construction.
The first coat of putty——500–600 m² per day,
The second coat of putty——800–1000 m² per day.
Since deployment, no safety incidents have occurred. The robot features dual active and passive safety systems, providing comprehensive protection for worry-free operation.
One-touch tablet control with an intuitive visual UI requires no programming skills. Ordinary workers can independently run the construction painting robot after basic training. Built-in standardized spraying programs enable quick start-up, eliminating complex manual adjustments and errors.
Thanks to the combined effect of the robot’s built-in filtration system and the dedicated mixer, the risk of failure is significantly reduced, ensuring stable and reliable performance. Legend Robot also offers a professional after-sales support that provides prompt response and reliable service.
