Information

Putty adhesion will directly affect the construction quality of the paint. Many projects find that the putty has poor adhesion during the construction process, but the exterior wall putty construction has been completed in a large area. Considering various factors such as construction period and cost, the exterior wall can no longer be replaced. Putty, in this case, is there a way to improve the adhesion of putty?

Encountered projects that have already been constructed, and found that the adhesion of the external wall putty is poor, the following methods can be used to improve the adhesion of the putty:

1. Water spray maintenance method to improve the adhesion of putty

The main component of exterior wall putty is cement, which will increase its strength when exposed to water. Therefore, after the exterior wall putty construction is completed, the putty can be cured by rolling or spraying water to improve the adhesion of the putty.

2. Transparent penetrating primer improves the adhesion of putty

Once you find that the adhesion of exterior wall putty is poor, you must not use colored alkali-resistant sealing primer. Use transparent sealing primer. Compared with colored primer, transparent sealing primer has better permeability, which can strengthen exterior wall putty and improve Putty adhesion.

3. Properly add water to the sealing primer to improve the adhesion of the putty

During the construction of many projects, the primer is used directly after opening the barrel, which will affect the permeability of the primer; a reasonable approach is to properly dilute the primer with water so that the primer can penetrate into the putty base layer, thereby improving the exterior wall putty Adhesion.

4. Avoid direct sunlight on the wall during primer construction to improve the adhesion of putty

Especially in summer, the temperature of the wall exposed to direct sunlight is very high. The primer will quickly form a film after rolling and cannot penetrate into the base layer of the external wall, which will cause poor adhesion. On the contrary, avoid the wall exposed to direct sunlight. Add more water to the primer to allow the primer to fully penetrate the putty base layer, which will improve the adhesion of the putty.
