Many people see their house decorated with white putty powder is so smooth and bright, but some putty powder will appear blistering phenomenon, do you know why, for you to analyze the reasons, as long as the construction avoids the next will make a bright wall.

　　1.基材吸水量過低。導致膩子批刮時相對保水時間過長而使膩子在墻上長期處于漿料態而不干，使氣泡不容易被泥刀擠壓出！而產生針孔狀毛孔，就是為什么工程上批刮模板頂比墻體氣泡更多的原因，墻體吸水量大，而模板頂吸水量極低。

　　1. The water absorption of the base material is too low. As a result, the relative water holding time of the putty scraping is too long, and the putty is in the slurry state on the wall for a long time, so that the bubbles are not easy to be squeezed out by the mud knife! The pinhole pore is the reason why there are more bubbles on the top of the scraping formwork than on the wall. The water absorption of the wall is large, while the water absorption of the top of the formwork is very low.

　　2.單遍批刮太厚，膩子孔隙中的空氣沒有壓擠出來。

　　2. The air in the pore of putty is not extruded because the single batch scraping is too thick.

　　3.基層過于粗糙，有細小孔洞。批刮時膩子將孔洞內空氣壓縮，之后空氣壓力反彈形成氣泡。

　　3. The base is too rough with small holes. The putty compresses the air in the hole during batch scraping, and then the air pressure rebounds to form bubbles.

　　4.耐水涂料、高標號混凝土等密閉性好的基面不透起泡。

　　4. Waterproof coatings, high-grade concrete and other well-sealed base surfaces are impervious to foaming.

　　5.基層過于干燥，吸水率過高，易致面層膩子氣泡多。

　　5. The base is too dry, the water absorption rate is too high, and the surface putty is easy to cause more bubbles.

　　6.纖維素添加量過大。

　　6. Excessive cellulose addition.

　　7.高溫施工時膩子易產生氣泡。

　　7. Putty is easy to produce bubbles during high temperature construction.

　　選擇合格的膩子粉，加上施工的正確性會做出滿意的效果。

　　Selection of qualified putty powder, together with the correctness of construction, will achieve satisfactory results.
