The main performance of water whitening of stone like paint: Although the paint is completely dry, it will still turn white after exposure to water, and the paint will become loose. After drying in the sun, the coating still can not restore the original color and luster. The main reasons for the whiteness of stone paint exposed to water are as follows:

In the production process of genuine lacquer, an unsuitable emulsion was added. In order to increase the stability of emulsion, some emulsion manufacturers use excessive surfactants. The presence of these surfactants will greatly reduce the water resistance of the emulsion itself.

In order to save cost, only a small amount of emulsifier is added by the stone like paint manufacturer, so the paint film is loose and not dense enough after the stone like paint is dried. The film has high water absorption and low bonding strength. In the long-term rainy weather, the rain will gradually penetrate into the paint film, so as to make the paint film white.
