[0002] Over time, the exterior walls of buildings may fade, crack, corrode, etc., seriously affecting the beauty of the building. Through exterior wall renovation, these old and damaged exterior wall materials can be replaced with new materials, cracks and damage can be repaired, and the building can be renewed and rejuvenated.

[0003] In the process of exterior wall renovation, putty, primer, midcoat and other coatings are often used to brush the exterior wall to achieve the purpose of exterior wall renovation. When applying paint, putty is usually the first process, which is used to perform preliminary leveling of the base layer. Then comes the primer to enhance the adhesion of the base layer and the moisture-proof and anti-corrosion effect. Finally, the midcoat is used to further process the putty layer to improve the protective effect.

[0004] However, such a construction scheme often requires more processes, which not only takes a long time to construct, but also requires a lot of manpower, thus increasing the cost of exterior wall renovation. In addition, it is easy to cause delamination between putty, primer and midcoat, which affects the integrity of the coating and leads to unsatisfactory anti-corrosion effect.
