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.基材吸水量过低。导致腻子批刮时相对保水时间过长而使腻子在墙上长期处于浆料态而不干，使气泡不容易被泥刀挤压出！而产生针孔状毛孔，就是为什么工程上批刮模板顶比墙体气泡更多的原因，墙体吸水量大，而模板顶吸水量极低。

　　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.单遍批刮太厚，腻子孔隙中的空气没有压挤出来。

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

　　3.基层过于粗糙，有细小孔洞。批刮时腻子将孔洞内空气压缩，之后空气压力反弹形成气泡。

　　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、高标号混凝土等密闭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.基层过于干燥，吸水率过高，易致面层腻子气泡多。

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

　　6.纤维素添加量过大。

　　6. Excessive cellulose addition.

　　7.高温施工时腻子易产生气泡。

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

　　选择合格的腻子粉，加上施工的正确性会做出满意的效果。

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