Because of the stress deformation of the wall structure, cracks often appear after the completion of the external wall decoration. Some people think that cement-based putty powder for exterior wall is easy to crack. As long as the product has high elasticity, the crack problem can be solved. The specific situation of the crack is as follows:

　　了解我国建筑史(1)每个人都知道，建筑质量问题是由于设计、施工、材料、木材、中国古建筑——北京故宫的城墙，使用弹性外墙腻子粉，现在560年过去了，没有出现裂缝、开裂、脱落墙面革、渗水等问题。

　　To understand the history of architecture in China (1) everyone knows that the quality of architecture is due to the design, construction, materials, wood, the wall of Beijing Imperial Palace, the ancient Chinese architecture, and the use of elastic putty powder for external walls. Now 560 years have passed, there are no cracks, cracks, peeling off wall leather, water seepage and other problems.

　　而我们所谓的现代高科技产品，如“真石漆”、“乳胶漆”、“氟碳漆”、“釉面瓷砖”、“弹性腻子”、“GS防水材料”等，可以有几年、几十年、几百年的使用寿命。采用弹性腻子的建筑，在材料和工艺上均可达到故宫博物院的水平。

　　And our so-called modern high-tech products, such as "real stone paint", "latex paint", "fluorocarbon paint", "glazed ceramic tile", "elastic putty", "GS waterproof material", can have several years, decades, hundreds of years of service life. The building with elastic putty can reach the level of the Palace Museum in material and technology.

　　现代建筑工程，包括基础设施建设和装修，由于施工高峰期，为节省资金和麻烦，质量隐患较多，是多年以后，这些隐患依然存在，薄层腻子，尤其是弹性腻子不能从根本上解决这些问题。

　　Modern construction engineering, including infrastructure construction and decoration, has many quality hidden dangers due to the peak period of construction, in order to save money and trouble. After many years, these hidden dangers still exist. Thin layer putty, especially elastic putty, cannot fundamentally solve these problems.

　　弹性腻子的重要技术指标之一:动态抗裂性(底部开裂)≥0.1mm， <0.3mm。

　　One of the important technical indexes of elastic putty: dynamic crack resistance (bottom crack) ≥ 0.1mm, < 0.3mm.

　　外墙腻子粉,以满足这个索引是很容易的,我们添加更多的好的弹性乳液可以做,问题是当乳胶材料数量越大,影响越大基于水泥的后期强度和稳定的腻子,弹性乳胶维持时间是非常有限的。

　　External wall putty powder is easy to meet this index. We can add more good elastic emulsion to do it. The problem is that the larger the amount of latex material, the greater the impact. The strength of cement and the stable putty, the maintenance time of elastic latex is very limited.

　　墙体产生裂缝后,可以存在,及其裂纹大小,每,每一小时,24小时不断变化的,它会随环境温度的变化,湿度和变化,这种变化可以继续建筑使用寿命结束的时候,要选择质量好、灵活性好外墙腻子粉。

　　After the wall cracks, it can exist permanently, and its crack size will change continuously every day, every hour and 24 hours. It will change with the change of ambient temperature, humidity and change. This change can continue to the end of the service life of the building. When the quality and flexibility of the external wall putty powder are good, it is necessary to choose.
