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?

　　遇到曾經(jīng)施工的項目，發(fā)現(xiàn)外墻膩子附著力差，能夠經(jīng)過以下幾個方法來改善膩子附著力：

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

　　1、淋水頤養(yǎng)辦法改善膩子附著力：外墻膩子主要成份是水泥，水泥遇水后會增增強度。因而，外墻膩子施工完成后，能夠滾涂或噴水辦法養(yǎng)護膩子，進步膩子附著力。

　　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、透明浸透底漆改善膩子附著力：一旦發(fā)現(xiàn)外墻膩子附著力差，千萬不能運用有色抗堿封鎖底漆，要運用透明封鎖底漆，透明封鎖底漆相關于有色底漆，浸透性會比擬好，可以強化外墻膩子，進步膩子附著力。

　　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、封鎖底漆恰當加水進步膩子附著力：很多項目在施工時，底漆開桶后直接運用，這樣會影響底漆的浸透性；合理的做法是，封鎖底漆恰當加水稀釋，讓底漆可以浸透到膩子基層里面，從而進步外墻膩子附著力。

　　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、底漆施工時避開陽光直射墻面能夠改善膩子附著力：特別是在夏天，陽光直射的墻面溫度十分高，底漆滾涂后很快成膜，不可以浸透到外墻基層里，就會形成附著力差，相反，避開陽光直射的墻面，底漆恰當多加水，讓底漆充沛浸透到膩子基層里，會進步膩子附著。

　　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.
