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?

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. 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. 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. 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. 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.
