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?

　　在現有施工項目中，發現外墻膩子附著力較差。可采用以下方法提高膩子的附著力:

　　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、澆筑養護方法提高膩子的附著力:外墻膩子的主要成分是水泥，水泥會增加水的強度。因此，外墻膩子施工后，可以通過滾涂或噴水來保養，以提高膩子的附著力。

　　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、透明滲透底漆提高膩子的附著力:一旦發現外墻膩子的附著力差,不要用有色抗堿底漆、使用透明的封閉底漆,透明密封引物相對于有色底漆、滲透率會更好,可以加強外墻膩子,提高膩子的附著力。

　　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、密封底漆適量的水，提高膩子的附著力:很多工程施工中，底漆直接使用后打開，會影響底漆的滲透性;合理的做法是關閉底漆，適當加水稀釋，使底漆能夠滲透到膩子的底面，從而提高外墻膩子的附著力。

　　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、底漆施工遠離陽光直射墻面可以提高膩子的附著力,特別是在夏天,陽光直射的墻面溫度非常高,底漆滾涂膜后不久,不能夠深入基層墻上,會導致附著力差,相反,遠離陽光直射的墻面,適當底漆更多的水,讓底漆充分滲透到基層膩子中，提高膩子粘合力。

　　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.
