Because the main body of the building structure adopts a reinforced concrete structure, alkaline substances continuously seep out in the using process due to the characteristics of cement, if no sealing measure is adopted, the coating can quickly generate the conditions of efflorescence, fading, pulverization and the like, the whole coating effect and the protection life are influenced, and for the renovation of the existing building, because the conditions of the original wall surface are complex, such as oil stain, pulverization and the like, and if primer is not adopted, the coating after construction is easy to drop, crack and the like.
In the actual construction process, because the primer coating needs to be carried out by one additional labor, the conditions that construction workers do not coat the primer, the primer coating is not uniform or the primer is directly added into the finish paint for construction can occur under many conditions, so that a large number of building decoration adverse conditions are caused.
Therefore, the building interior and exterior wall coating with the integrated bottom and interior walls is developed, the purposes of sealing and strengthening the wall base layer and achieving the decorative effect by one-time construction are achieved, a large amount of labor cost can be saved, the problems caused by multiple constructions are reduced, the work efficiency is improved, the consumption of primer can be saved, the consumption of raw materials is reduced, and good social and economic benefits are achieved.
