In the process of using light plastering gypsum, I believe many people are still easy to see a phenomenon: blistering. Now, after a period of construction, the foam problem seriously endangers the actual effect of the beautiful and decent wall. Especially after the construction, we must make a thorough analysis of the cause and do well in the project construction before the project is built, so as to prevent this kind of behavior from happening.

下面，抹灰石膏廠家帶大家了解一下問題怎樣解決！首先，膩子表面起泡的原因可能是：基層太粗糙，配料速度太快；一次施工膩子層過厚，大于2.0mm；基層含水量過高，密度過大或過小。膩子孔隙豐富，含水率高，密封性好，空氣封閉在孔隙中，不易解決。施工一段時間后，表面剝落主要是使用抹灰石膏時攪拌不均勻造成的。泥漿中含有不能及時溶解的粉狀顆粒。

Next, the plaster manufacturer will show you how to solve the problem! First of all, the reasons for the foaming of putty surface may be: the base course is too rough and the batching speed is too fast; The putty layer for one-time construction is too thick, greater than 2.0mm; The water content of the base course is too high, and the density is too large or too small. The putty has rich pores, high moisture content, good sealing performance, and the air is sealed in the pores, which is not easy to solve. After a period of construction, the surface peeling is mainly caused by uneven mixing when plastering gypsum is used. The mud contains powdery particles that cannot be dissolved in time.

施工后大量吸水膨脹形成剝落；如果基層太干，墻體吸水率太高或水泥標號太高，容易產生氣泡。泡泡的地方到處都是空洞。分析原因后，在施工中應做好以下幾點：出現大面積氣泡的膩子面，用刮刀直接將小氣泡口壓碎，重新粉刷石膏刮去發泡面層；膩子粉一般攪拌均勻，靜置10分鐘左右，再用電動攪拌機在墻上再次攪拌。二是施工中如有起泡現象，在去除水印前應先用刮刀去除起泡，以保證墻面無氣泡。

After construction, a large amount of water absorption and expansion form peeling; If the base course is too dry, the water absorption of the wall is too high or the cement grade is too high, it is easy to produce bubbles. Bubbles are full of holes. After analyzing the causes, the following points should be done during construction: for the putty surface with large bubbles, crush the small bubble mouth directly with a scraper, repaint gypsum and scrape off the foaming surface; Generally, the putty powder shall be stirred evenly, left for about 10 minutes, and then stirred again on the wall with an electric mixer. Second, if there are bubbles during construction, remove the bubbles with a scraper before removing the watermark to ensure that there are no bubbles on the wall.

1、若墻面氣泡或空鼓較小，可打磨處理，然后刷界面增強劑，再分批刮除；

1. If the bubble or hollowing on the wall is small, it can be polished, then brushed with interface enhancer, and then scraped off in batches;

2、如果墻面空鼓較大，造成大面積脫落，建議全部拆除后刷上界面加強劑，然后批刮。抹灰前應將基層清理干凈，抹灰前澆水，注意砂漿配合比，使底層砂漿與地面粘結牢固；抹灰應分層分次壓實。踢腳板和踢腳板施工操作要小心，認真吊垂直，拉線找直找方，抹灰后用板尺刮平，上口要壓實平整。

2. If the hollowing of the wall is large, resulting in large area falling off, it is recommended to brush the interface reinforcing agent after all removal, and then scrape it in batches. The base course shall be cleaned before plastering, watered before plastering, and the mortar mix proportion shall be paid attention to to ensure that the bottom mortar is firmly bonded with the ground; Plastering shall be compacted in layers and times. The construction operation of skirting board and skirting board shall be careful. The skirting board shall be hoisted vertically, and the wire shall be straightened and square. After plastering, it shall be scraped with a board ruler, and the upper mouth shall be compacted and leveled.
