Putty powder is a kind of material used in construction. Putty powder is generally used as a foundation before wall painting. The next step can only be carried out after the putty powder is painted and dried thoroughly. But what should we do if the putty powder will fall off after it is dry. Next, let Fuhua building materials show us.

一、膩子粉掉粉的原由：

1、 The reasons of putty powder dropping are as follows:

1、內墻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會脫粉。

1. If the polishing time of internal wall putty powder is not well controlled, the powder will be removed after polishing after the surface is dry.

2、膩子粉批刮比較薄，在夏天高溫條件下，水分揮發過快造成膠黏體系破壞，因而容易脫粉。

2. Putty powder scraping is relatively thin. Under the high temperature condition in summer, the moisture volatilizes too fast, resulting in the destruction of the adhesive system, so it is easy to remove the powder.

3、產品超過保質期，粘結力度大幅度下降。

3. When the product exceeds the shelf life, the bonding strength decreases greatly.

4、產品儲存不當，吸潮后粘結力大幅度下降。

4. If the product is not stored properly, the adhesive force will decrease greatly after moisture absorption.

5、基層吸水率高，導致膩子干燥速度很快，沒有充足的水分進行固化。

5. Because of the high water absorption of the base course, the putty drying speed is very fast, and there is not enough water for curing.

二、掉粉解決方法

2、 Solution of powder dropping

1、內墻膩子面層拋光時要掌握適宜的拋光時間，拋光的時期就是待膩子表面水印消失后，立即進行拋光。

1. When polishing the putty surface of interior wall, we should master the appropriate polishing time. The best polishing time is to polish immediately after the watermark on the putty surface disappears.

2、內墻膩子批刮時，將厚度控制在1-2mm之間，這樣可以有效避免厚度太薄造成的脫粉以及厚度太厚造成的膩子開裂。

2. When scraping the inner wall putty, it is better to control the thickness between 1-2mm, which can effectively avoid the powder removal caused by too thin thickness and the putty cracking caused by too thick thickness.

3、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。

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

4、產品一定要注意防水處理，應存在在陰涼干燥處，并且保證包封完好。

4. Products must pay attention to waterproof treatment, should exist in a cool and dry place, and ensure good encapsulation.

5、夏天或高溫強風氣候條件下，在施刮膩子前先用清水潤濕墻面，墻面表面無明水后即可批刮膩子。

5. In summer or high temperature and strong wind climate, it is better to wet the wall with clean water before applying putty, and the putty can be applied after there is no clear water on the wall surface.

膩子粉是我們現在裝修時很長用到的材料，如果膩子粉在干后嚴重掉粉的話，那么我們只能重新粉刷一遍了。如果大家想要購買膩子粉的話，可以向我們濟南膩子粉廠家進行購買。

Putty powder is the material we use for a long time in decoration. If putty powder drops seriously after drying, we can only paint it again. If you want to buy putty powder, you can buy it from Jinan putty powder manufacturer.
