The relationship between the performance and quality of putty powder for exterior wall and the interface of base layer depends fundamentally on the quality and performance of various materials selected by putty. If the performance is stable and the quality of raw materials used is good, there will not be too many problems in production. Whether it is manual or mechanical mixing, as long as the mixing is uniform, the quality of putty powder for exterior wall can be guaranteed. In terms of project quality assurance, attention should be paid to the relationship between grass-roots level and interface.

　　基层和基层界面的处理包括以下内容:

　　The treatment of grass-roots and grass-roots interface includes the following contents:

　　1. 稳定的基础。在基地的建设进行仔细的检查和确认,外墙腻子粉的价格,检查基础的平面度、强度、基地吸水率,基本没有粉,宽松,碱的现象,没有明显的裂纹,裂纹(水墙方法检查),基础是否稳定。如果基础不能达到外墙腻子粉的施工要求，应先做相应的技术处理，如果基础满足外墙腻子粉的施工要求，则可以进行外墙腻子粉的施工。

　　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. 基础的强度必须大于外墙腻子粉的强度。根据粘接材料的理论和实践，如果墙体基层的强度小于外墙腻子粉，外墙腻子粉容易出现“拔根”、空鼓、脱落等现象。如果基础强度大于外墙腻子粉的强度，这些问题就不会发生。

　　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.严格处理界面。清除浮灰，外墙先为良好的腻子粉、油污(包括脱模剂)，填补吹基层的裂缝，挑出凹凸不平的地方，如基层有明显不平之处，先用抗裂砂浆作平整。如基础尤为干燥,吸水性强,环境气候非常干燥,会影响外墙腻子粉粉和基层的附着力和力量,因此,建议在施工之前,水湿墙基层,然后建设外墙腻子粉,如果条件允许,建设2 - 3天后,可以湿养护1 - 2次,抗裂效果和强度会更好。

　　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.
