In the building coatings market, stone-like paint, real stone paint, and multicolor coating are often used interchangeably, causing cognitive confusion for consumers and industry practitioners. Recently, industry experts have conducted in-depth disassembly from the dimensions of concept, formula and process to help the market clarify the essential differences between the three.
    Stone-like paint is essentially a marketing concept, not a strict product classification. As long as it presents a stone texture through formula and construction, regardless of the system and process, it can be called stone-like paint, covering interior texture paint, exterior real stone paint, multicolor coating, etc. Its core is the simulation of visual effects, not fixed technical standards.
    Real stone paint is a clearly defined product. Its core feature is that more than 70% of the formula consists of sand and powder of different meshes, with visible sand particle distribution on the surface and obvious granular feel when touched. Its reference formula shows that emulsion accounts for only about 20%, mainly used to bond sand and stone. The visual effect core relies on natural aggregates themselves, and the formula structure is relatively simple.
    Multicolor coating is an independent product system, with water-in-water sand as the mainstream, composed of three parts: base paint, granulating liquid and continuous phase. The paint formation requires steps such as color mixing, sand addition (no sand for water-in-water system), color dot cutting, and mixing with continuous phase. The color dot effect is significantly affected by the construction technique. Emulsion is a core control factor in multicolor coatings, determining the formation, stability and color performance of color dots. Its formula and process complexity are higher than that of real stone paint, and the price is also relatively higher.
    It is worth noting that the number of colors is not the distinguishing standard of the three. Real stone paint can achieve multiple colors by mixing colored sand, and multicolor coating can also be made into a single color. The key difference lies in whether the color source is natural aggregates or color dot structure. In terms of construction, the spray gun structure of real stone paint is simple, and the air pressure needs to be fully opened to ensure atomization; multicolor coating needs to coordinate the pressure of the air valve and the discharge container to avoid color dot damage, which has higher requirements for construction experience.
