外墙腻子粉掉粉原因

Reasons for peeling of exterior wall putty powder

1、材料本身及其配比问题;

1. Material itself and its proportion;

2、施工问题:涂抹过薄;加水后搅拌不充分，助剂没有完全发挥作用;

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、气候因素:高温干燥、强光照射、强风气候，容易失水过快;

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

4、基层受潮或不牢固;

4. The base is damp or insecure;

5、基层吸水率太高(墙面太干燥)，尤其是翻新墙面，导致腻子干燥速度过快，没有充足的水分进行固化;

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、产品超过保质期，粘结力度大幅度下降;

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

7、产品储存不当，吸潮后粘结力大幅度下降。

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

8、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答易脱粉。

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.

避免腻子掉粉的解决方法

Solution to avoid putty powder falling

1、对材料质量进行严格把关。

1. Strictly control the quality of materials.

2、基层吸水率太高导致腻子干燥太快，没有水分进行固化而起粉，解决办法就是刮腻子之前提前先用清水润湿尤其是翻新墙面。
