[0002] In the modern construction industry, the selection of exterior wall decoration materials is crucial for the overall aesthetics and durability of buildings. Traditional stone materials such as limestone are favored for their unique texture, color, and hardness, and are widely used in the decoration of building exterior walls. However, due to the weight of stone materials, they are prone to falling over time. Therefore, to meet the demand for exterior wall decoration, safer limestone-imitating stone material effect paint has emerged. Limestone-imitating stone material effect paint is mainly used to imitate limestone, German beige, lime stone, and other special irregular mottling series of stone materials, and is particularly suitable for the decoration of exterior facades of French buildings that pursue natural and elegant styles.

Currently, most limestone-imitating stone material effect paint products on the market have the following problems: the construction process of limestone-imitating stone material effect paint is complex, and the color point texture is prone to blooming, which tests the construction level of construction personnel and often results in problems such as the overall effect not matching the sample.
