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:

　　了解我國建筑史(1)每個人都知道，建筑質量問題是由于設計、施工、材料、木材、中國古建筑——北京故宮的城墻，使用彈性外墻膩子粉，現在560年過去了，沒有出現裂縫、開裂、脫落墻面革、滲水等問題。

　　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.

　　而我們所謂的現代高科技產品，如“真石漆”、“乳膠漆”、“氟碳漆”、“釉面瓷磚”、“彈性膩子”、“GS防水材料”等，可以有幾年、幾十年、幾百年的使用壽命。采用彈性膩子的建筑，在材料和工藝上均可達到故宮博物院的水平。

　　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.

　　現代建筑工程，包括基礎設施建設和裝修，由于施工高峰期，為節省資金和麻煩，質量隱患較多，是多年以后，這些隱患依然存在，薄層膩子，尤其是彈性膩子不能從根本上解決這些問題。

　　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.

　　彈性膩子的重要技術指標之一:動態抗裂性(底部開裂)≥0.1mm， <0.3mm。

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

　　外墻膩子粉,以滿足這個索引是很容易的,我們添加更多的好的彈性乳液可以做,問題是當乳膠材料數量越大,影響越大基于水泥的后期強度和穩定的膩子,彈性乳膠維持時間是非常有限的。

　　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.

　　墻體產生裂縫后,可以存在,及其裂紋大小,每,每一小時,24小時不斷變化的,它會隨環境溫度的變化,濕度和變化,這種變化可以繼續建筑使用壽命結束的時候,要選擇質量好、靈活性好外墻膩子粉。

　　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.
