However, the problems of peeling, bubbling, bursting, color change and the like of some wall surfaces can be caused, and the use effect of the external thermal insulation system of the external wall and the external wall coating is influenced. The reason for this is that, in addition to the quality of the coating, most of the primer is poorly understood or improperly used. The building outer wall base material is mostly cement mortar or concrete surface and is characterized by multiple gaps and strong alkalinity. The porous structure enables the water absorption of the coating to be strong, so that the surface of the coating is not smooth enough, the coating is easy to wrinkle, and the coating is dried too fast to crack the finish paint, so that the finish paint is wasted; and the strong alkalinity can cause the chemical degradation of resin in the coating, accelerate the aging of the coating film and reduce the service life of the coating. Therefore, the primer with excellent waterproof performance, alkali resistance and sealing performance is used in the coating of the outer wall, so that the outer heat insulation system of the outer wall can achieve better effect.
