Putty powder adhesion will directly affect the quality of paint construction, many projects found in the construction process that putty powder adhesion is poor, but the external wall putty powder construction has completed a large area, construction cost and other elements of thinking, once can not replace the external wall putty, this situation, whether there are ways to improve putty powder adhesion?

　　遇到曾经施工的项目，发现外墙腻子附着力差，能够经过以下几个方法来改善腻子附着力：

　　In the past construction projects, found that the external wall putty adhesion is poor, through the following ways to improve the putty adhesion:

　　1、淋水颐养办法改善腻子附着力：外墙腻子主要成份是水泥，水泥遇水后会增增强度。因而，外墙腻子施工完成后，能够滚涂或喷水办法养护腻子，进步腻子附着力。

　　1. Improving the adhesion of putty by soaking water: The main component of putty on external wall is cement, which will increase its strength when it meets water. Therefore, after the construction of putty for exterior wall is completed, it can be rolled or sprayed to maintain putty and improve the adhesion of putty.

　　2、透明浸透底漆改善腻子附着力：一旦发现外墙腻子附着力差，千万不能运用有色抗碱封锁底漆，要运用透明封锁底漆，透明封锁底漆相关于有色底漆，浸透性会比拟好，可以强化外墙腻子，进步腻子附着力。

　　2. Transparent soaking primer improves the adhesion of putty: once it is found that the adhesion of external wall putty is poor, we must not use colored alkali-resistant blocking primer. We should use transparent blocking primer. Transparent blocking primer is related to colored primer. The permeability of transparent blocking primer is comparable to that of colored primer. It can strengthen the adhesion of external wall putty and improve the adhesion of putty.

　　3、封锁底漆恰当加水进步腻子附着力：很多项目在施工时，底漆开桶后直接运用，这样会影响底漆的浸透性；合理的做法是，封锁底漆恰当加水稀释，让底漆可以浸透到腻子基层里面，从而进步外墙腻子附着力。

　　3. Blockade primer properly watered to improve putty adhesion: many projects in the construction, primer barrel directly after use, which will affect the permeability of primer; a reasonable approach is to block primer properly watered dilution, so that primer can be soaked into the base of putty, thereby improving the adhesion of external wall putty.

　　4、底漆施工时避开阳光直射墙面能够改善腻子附着力：特别是在夏天，阳光直射的墙面温度十分高，底漆滚涂后很快成膜，不可以浸透到外墙基层里，就会形成附着力差，相反，避开阳光直射的墙面，底漆恰当多加水，让底漆充沛浸透到腻子基层里，会进步腻子附着。

　　4. Avoiding direct sunshine during primer construction can improve the adhesion of putty: Especially in summer, the temperature of direct sunshine wall is very high, primer film is formed quickly after rolling, and can not be soaked into the outer wall base, which will result in poor adhesion. On the contrary, avoiding direct sunshine wall, primer should be properly watered, so that primer can be fully soaked into the base of putty, which will improve the adhesion of putty. With.
