1. The foundation of stability. Careful inspection and confirmation are carried out in the construction of the base. The price of putty powder for exterior wall, the flatness, strength and water absorption of the base are checked. There are basically no powder, loose and alkali phenomena, no obvious cracks, cracks (water wall method inspection) and whether the foundation is stable. If the foundation can not meet the construction requirements of putty powder for external wall, the corresponding technical treatment should be done first. If the foundation meets the construction requirements of putty powder for external wall, the construction of putty powder for external wall can be carried out.

　　2. The strength of foundation must be greater than that of putty powder for exterior wall. According to the theory and practice of bonding materials, if the strength of the wall base is less than that of the putty powder, the putty powder of the external wall is prone to "pull out", "empty drum" and "fall off". If the strength of foundation is greater than that of putty powder, these problems will not occur.

　　3. Strictly handle the interface. To remove floating ash, the outer wall should be made of good putty powder and grease (including release agent), fill the cracks in the blowing base, pick out the uneven areas, such as obvious unevenness in the base, and use crack-resistant mortar as leveling first. If the foundation is particularly dry, water absorption is strong, and the environment is very dry, it will affect the adhesion and strength of the putty powder and the base of the external wall. Therefore, it is suggested that before construction, the base of the water-wet wall should be built, and then the putty powder of the external wall should be built. If conditions permit, after 2-3 days, the putty powder of the external wall can be wet cured 1-2 times, and the crack resistance effect and strength will be better.
