墻面裝修時刮膩子粉一般需要2遍，刮膩子也容易產生很多問題，其中掉粉是比較嚴重的問題，膩子掉粉指的是膩子批刮上墻并經過一段時間干固后，用手指壓按揉搓墻面，手上沾滿白粉末，并且部分粉末掉落墻體。下面濟南膩子粉廠家來講講外墻膩子粉掉粉的原因以及解決方法。

When decorating the wall, it usually takes two times to apply putty powder, and it is easy to cause many problems when applying putty. Among them, powder falling is a relatively serious problem. The putty powder falling refers to that after the putty is applied to the wall in batches and dried for a period of time, the wall is rubbed with finger pressure, and the hands are covered with white powder, and some powder falls off the wall. Next, Jinan putty powder manufacturer will talk about the causes and solutions of the putty powder falling off the exterior wall.

外墻膩子粉掉粉原因

Reasons for peeling of exterior wall putty powder

1、材料本身及其配比問題;

1. Material itself and its proportion;

2、施工問題:涂抹過薄;加水后攪拌不充分，助劑沒有完全發揮作用;

2. Construction problem: too thin coating; The mixing is not sufficient after adding water, and the auxiliary agent does not fully play its role;

3、氣候因素:高溫干燥、強光照射、強風氣候，容易失水過快;

3. Climate factors: high temperature, dry, strong light, strong wind, easy to lose water too fast;

4、基層受潮或不牢固;

4. The base is damp or insecure;

5、基層吸水率太高(墻面太干燥)，尤其是翻新墻面，導致膩子干燥速度過快，沒有充足的水分進行固化;

5. The water absorption of the base layer is too high (the wall surface is too dry), especially the renovated wall surface, resulting in the drying speed of the putty is too fast, and there is not enough water for curing;

6、產品超過保質期，粘結力度大幅度下降;

6. When the product exceeds the shelf life, the bonding strength decreases significantly;

7、產品儲存不當，吸潮后粘結力大幅度下降。

7. Due to improper storage of the product, the adhesive force decreases greatly after moisture absorption.

8、膩子粉拋光時間掌握不好，表面已經干燥后再進行拋光處理就答易脫粉。

8. The polishing time of putty powder is not well controlled. If the surface is dry and then polished, it will be easy to remove the powder.

避免膩子掉粉的解決方法

Solution to avoid putty powder falling

1、對材料質量進行嚴格把關。

1. Strictly control the quality of materials.

2、基層吸水率太高導致膩子干燥太快，沒有水分進行固化而起粉，解決辦法就是刮膩子之前提前先用清水潤濕尤其是翻新墻面。

2. The high water absorption of the base layer causes the putty to dry too quickly, and there is no water to cure and powder. The solution is to wet the putty with water in advance, especially the renovated wall.

3、基層受潮或不牢固:基層進行防水處理，鏟除不牢固的基層后用抹灰材料找平后再刮膩子。

3. Damp or insecure base course: the base course shall be subject to waterproof treatment, and the unstable base course shall be removed and leveled with plastering materials before puttying.

4、天或高溫強風氣候條件下，在施刮膩子前好先用清水潤濕墻面,墻面表面無明水后即可施刮膩子。

4. In weather or high temperature and strong wind conditions, wet the wall with clean water before applying putty, and apply putty after there is no open water on the wall surface.

5、產品一定要在保質期內使用,如果超過保質期，必須進行試刮，經檢驗合格后，再行施工。

5. The product must be used within the shelf life. If it exceeds the shelf life, it must be scraped and tested before construction.

6、產品一定要注意防水處理，應存在陰涼干燥處。

6. The product must be waterproof and stored in a cool and dry place.

此外膩子粉掉粉可能是因為材料本身及其配比，還和施工問題、氣候因素都有關系。建議您在使用產品前后多去了解相應的內容問題以及預防措施，更好的進行施工。關注我們http://www.sjzmx.cn了解更多事項！
