The quality of putty powder adhesion coating will directly affect the construction. Many projects found that the adhesion of putty powder is poor in the construction process, but the construction of large-scale external wall putty powder has been completed, construction cycle and other aspects of cost considerations, can not change the external wall putty. In this case, is there any way to improve the adhesion of putty powder?

　　在现有施工项目中，发现外墙腻子附着力较差。可采用以下方法提高腻子的附着力:

　　In the existing construction projects, it is found that the external wall putty has poor adhesion. The following methods can be used to improve the adhesion of putty:

　　1、浇筑养护方法提高腻子的附着力:外墙腻子的主要成分是水泥，水泥会增加水的强度。因此，外墙腻子施工后，可以通过滚涂或喷水来保养，以提高腻子的附着力。

　　1. Casting and curing methods to improve the adhesion of putty: the main component of putty is cement, cement will increase the strength of water. Therefore, after putty construction, it can be rolled or sprayed to improve the adhesion of putty.

　　2、透明渗透底漆提高腻子的附着力:一旦发现外墙腻子的附着力差,不要用有色抗碱底漆、使用透明的封闭底漆,透明密封引物相对于有色底漆、渗透率会更好,可以加强外墙腻子,提高腻子的附着力。

　　2. Transparent penetrating primer improves the adhesion of putty: once it is found that the adhesion of external wall putty is poor, do not use colored alkali-resistant primer, use transparent sealing primer. Transparent sealing primer is better than colored primer and permeability. It can strengthen external wall putty and improve the adhesion of putty.

　　3、密封底漆适量的水，提高腻子的附着力:很多工程施工中，底漆直接使用后打开，会影响底漆的渗透性;合理的做法是关闭底漆，适当加水稀释，使底漆能够渗透到腻子的底面，从而提高外墙腻子的附着力。

　　3. Sealing primer proper amount of water, improve the adhesion of putty: In many engineering construction, the opening of primer directly after use will affect the permeability of primer; the reasonable way is to close the primer, add water to dilute properly, so that the primer can penetrate into the bottom of putty, thereby improving the adhesion of external wall putty.

　　4、底漆施工远离阳光直射墙面可以提高腻子的附着力,特别是在夏天,阳光直射的墙面温度非常高,底漆滚涂膜后不久,不能够深入基层墙上,会导致附着力差,相反,远离阳光直射的墙面,适当底漆更多的水,让底漆充分渗透到基层腻子中，提高腻子粘合力。

　　4. Primer construction can improve the adhesion of putty, especially in summer, the wall temperature of direct sunshine is very high. Shortly after primer roll-coating, it can not penetrate into the base wall, which will lead to poor adhesion. On the contrary, far away from the wall directly sunshine, appropriate primer more water, so that primer can fully penetrate into the base putty. In order to improve the adhesion of putty.
