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、腻子粉掉粉的原由：

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

1、内墙腻子粉抛光时间掌握不好，表面已经干燥后再进行抛光处理就会脱粉。

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、腻子粉批刮比较薄，在夏天高温条件下，水分挥发过快造成胶黏体系破坏，因而容易脱粉。

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、产品超过保质期，粘结力度大幅度下降。

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

4、产品储存不当，吸潮后粘结力大幅度下降。

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

5、基层吸水率高，导致腻子干燥速度很快，没有充足的水分进行固化。

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、掉粉解决方法

2、 Solution of powder dropping

1、内墙腻子面层抛光时要掌握适宜的抛光时间，抛光的时期就是待腻子表面水印消失后，立即进行抛光。

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、内墙腻子批刮时，将厚度控制在1-2mm之间，这样可以有效避免厚度太薄造成的脱粉以及厚度太厚造成的腻子开裂。

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、产品一定要在保质期内使用，如果超过保质期，必须进行试刮，经检验合格后，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、产品一定要注意防水处理，应存在在阴凉干燥处，并且保证包封完好。

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

5、夏天或高温强风气候条件下，在施刮腻子前先用清水润湿墙面，墙面表面无明水后即可批刮腻子。

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.
