膩子層偶爾出現開裂、起泡、空鼓等問題。請問這是什么原因？所謂“三分料、七分工”，濟南膩子粉廠家認為除了優良的產品質量，良好的施工工藝起著重要的作用！

Occasionally, the putty layer may experience cracking, blistering, hollowing, and other issues. May I ask what is the reason for this? The so-called "three parts and seven division of labor", Jinan putty powder manufacturer believes that in addition to excellent product quality, good construction technology plays an important role!

膩子打磨后出現劃痕的原因：

Reasons for scratches after putty polishing:

①拌時混入顆粒狀物質；

① Mix with granular substances during mixing;

②膩子產品本身較細膩，打磨時使用砂紙的目數與膩子不匹配，從而導致后期墻面漆噴涂后無法遮蓋。

② The putty product itself is relatively delicate, and the mesh size of sandpaper used during polishing does not match the putty, resulting in the inability to cover the wall after later painting.

解決辦法：

Solution:

膩子打磨須選用360目及以上水砂紙進行打磨。批刮膩子后，膩子層開裂是怎么造成的，如何處理？

Putty polishing must be done using water sandpaper with a mesh size of 360 or above. How is the cracking of the putty layer caused after applying putty in batches and how to handle it?

膩子開裂的原因：

Reasons for putty cracking:

①干濕變化形成的干縮裂縫；

① Dry shrinkage cracks formed by changes in dry and wet conditions;

②溫度變化與熱脹冷縮引起的溫度裂縫；

② Temperature cracks caused by temperature change and thermal expansion;

③墻體結構變形引起的結構裂縫等。

③ Structural cracks caused by deformation of the wall structure.

④施工工藝（批刮厚度、界面處理）、養護方式等諸多因素都可能引發膩子開裂。

④ Construction techniques (batch thickness, interface treatment), maintenance methods, and many other factors may cause putty cracking.

解決辦法：

Solution:

微小裂紋：打磨，涂刷墻錮后，然后批刮膩子，注意控制厚度；

Minor cracks: After polishing and brushing the wall, apply putty in batches, and pay attention to controlling the thickness;

大裂紋及空鼓：鏟除后涂刷墻錮，再進行膩子批刮；

Large cracks and hollows: After removal, apply wall adhesive and then apply putty batch scraping;

結構性裂紋：鏟除至基層，涂刷墻錮，對結構性裂紋進行修補，然后進行基層抹灰處理，并做加強，再進行膩子批刮。

Structural cracks: Remove to the base layer, apply wall adhesive, repair the structural cracks, then plaster and strengthen the base layer, and then apply putty batch scraping.

膩子層粉化嚴重是怎么造成的，應該如何處理？

How is the severe powdering of the putty layer caused and how should it be handled?

膩子粉化的原因：

Reasons for putty powdering:

①批刮膩子層過薄

① Apply putty layer too thin in batches

②強制通風

② Forced ventilation

③攪拌不均勻

③ Uneven mixing

解決辦法：

Solution:

輕度掉粉可以用濕毛巾將浮灰處理掉，然后用墻錮進行界面處理，再進行批刮即可；

Mild powder loss can be treated with a wet towel to remove the floating ash, followed by wall bonding for interface treatment and batch scraping;

膩子層如粉化嚴重，則建議鏟除后用墻錮做界面處理再進行批刮。

If the putty layer is severely powdered, it is recommended to remove it and then use wall bonding for interface treatment before batch scraping.

膩子層起泡、空鼓是怎么造成的，應該如何處理？

How is the blistering and hollowing of the putty layer caused and how should it be handled?

膩子層空鼓、起泡的原因：

Reasons for hollowing and foaming of the putty layer:

①基層處理不當，如有浮塵、疏松或光滑等，使膩子層與基層接觸不夠緊密，形成夾層；

① Improper treatment of the base layer, such as floating dust, looseness, or smoothness, results in insufficient contact between the putty layer and the base layer, forming an interlayer;

②基層與膩子層之間存在致密層，如用界面劑不加水稀釋進行界面處理，使空氣無法正常向基層擴散。

② There is a dense layer between the base layer and the putty layer. If interface agent is used without water dilution for interface treatment, it will prevent air from spreading to the base layer normally.

解決辦法：

Solution:

如果墻面氣泡或空鼓較小，可以通過打磨的方式處理后再用墻錮進行界面處理，然后批刮； 如果墻面空鼓較大，已經造成大面積脫落，則建議全部鏟除后用墻錮系列進行處理，然后批刮。

If the bubbles or hollows on the wall are small, they can be polished and then treated with wall bonding for interface treatment, and then scraped in batches; If there is a large hollowing on the wall, which has caused a large area of detachment, it is recommended to completely remove it and then use the Wall Gu series for treatment, and then batch scrape it.
