[0002] As the architectural decoration market increasingly embraces "green" and "natural" decorative concepts, and demand for low-carbon, environmentally friendly exterior wall coatings becomes increasingly stringent, natural stone paint offers a compelling alternative to stone-like finishes. Its superior performance, including high fidelity, strong stone texture, strong decorative properties, safe use, and long service life, complements its affordable and high-quality stone-like finish. Buildings finished with natural stone paint exhibit a natural, authentic color, creating an elegant, harmonious, and dignified aesthetic. Suitable for both interior and exterior decoration of all types of buildings, natural stone paint is particularly effective on curved surfaces, creating a vivid, lifelike effect and a return to nature. As a result, it has become a leading coating material for exterior wall finishing in my country. Natural stone paint demands high surface quality, including consistent coating thickness, strong adhesion, uniform color, and the absence of color bridging, white streaking, dripping, blisters, or brush marks.

[0003] In the prior art, a spray gun is usually used for spraying real stone paint. An operator holds the spray gun and moves it along the surface, and manually controls the distance between the spray gun and the surface.

[0004] However, the strength of the operator's holding the spray gun and the distance between the nozzle and the finish are greatly affected by time, fatigue and replacement of operators, resulting in uneven spraying, uneven surface thickness, white stripes, flow and other problems, and later peeling, which seriously affects the appearance.
