The large color difference exists in a dry and wet state, and particularly, when the surface is dry, the surface is dull and obviously whitened, so that the stone-like visual effect is seriously influenced. The common finishing agent can improve the gloss and reduce the dry-wet color difference of the surface after being sprayed on the surface, but the inner pores of the PC stone-like water permeable brick are changed into hydrophobic property to ensure that the PC stone-like water permeable brick is impermeable to water.
