The adhesion of putty powder has a great influence on the later wall painting, so it is very important to improve the adhesion of putty powder. The following to introduce several methods to enhance the adhesion of wall putty, for your reference.

1）墻膩子主要成份是水泥，遇水后會增加強(qiáng)度。所以，墻面施工完后滾涂或噴水方法養(yǎng)護(hù)膩子，以此提高膩子附著力。

1) The main component of wall putty is cement, which will increase the strength when meeting water. Therefore, after the wall construction, roll coating or water spraying method is used to maintain the putty, so as to improve the putty adhesion.

2）如果墻面膩子附著力差，使用透明封閉底漆，透明封閉底漆相對于有色底漆，滲透性會比較好，能夠強(qiáng)化外墻膩子，提高膩子附著力。

2) If the wall putty has poor adhesion, the transparent sealing primer has better permeability than the colored primer, which can strengthen the putty and improve the putty adhesion.

3）底漆開桶后影響底漆滲透性；正確做法是封閉底漆適當(dāng)加水稀釋，讓底漆能夠滲透到膩子基層里面，從而提高外墻膩子附著力

3) After the primer is opened, the permeability of the primer will be affected; the correct way is to add water to dilute the primer, so that the primer can penetrate into the putty base, so as to improve the adhesion of the putty on the exterior wall

4）夏天，墻面受陽光照射溫度高，底漆滾涂后很快成膜，不能夠滲透到外墻基層里，就會造成附著力差，相反，避開陽光直射的墻面，底漆適當(dāng)多加水，讓底漆充分滲透到膩子基層里，會提高膩子附著。

4) In summer, the temperature of the wall exposed to sunlight is high, and the primer roll coating will form a film quickly, which will cause poor adhesion. On the contrary, to avoid the direct sunlight on the wall, add more water to the primer to make the primer fully penetrate into the putty base, which will improve the putty adhesion.
