^_^ Good luck and prosperity ^_^
I previously had a balcony painted with interior wall paint, which has become a bit loose. Now I want to change to Meihui water-based sand. How can I ensure that the base is not loose and more solid during construction?
Teacher Wu from Meihui Technical Service Department:
This type of problem can be analyzed in two situations regarding the looseness of the base.
The first situation is that the underlying putty layer is loose. In this case, it is recommended to scrape it off and reapply. If the looseness of the underlying putty layer is not resolved, no matter how the construction is done on top, it is easy to have delamination; furthermore, after scraping off the loose putty layer, we need to pay attention to applying wall primer before applying the putty layer, otherwise, the strength of the underlying cement mortar layer may be insufficient.
The second situation is that the strength of the underlying putty layer is still intact. We only need to sand and roll the interface, and fill in the areas that need to be filled. If the wall is relatively flat, we can directly apply sealing, primer, middle coat, and top coat without reapplying the putty layer; if the wall is relatively uneven, after finishing the interface, we need to reapply and sand the putty layer before proceeding with sealing, primer, middle coat, and top coat.

Why does the top coat look uneven after it dries?
Zhao Guozhi, Meihui dealer from Tiantai County, Zhejiang:
Analysis:The main reason for this is uneven rolling:
1. Missing spots. Meihui stone texture paint R series coarse surface, some areas cannot be rolled evenly;
2. Multiple rolling. Local repeated rolling is not uniform, especially in coarse surface depressions, which can easily cause material accumulation.
Recommended solution:1. Apply two coats of top coat. Especially when applying the first coat, it needs to be rolled evenly; 2. Pay attention to rolling at the joint positions, and when rolling multiple times, ensure that excess material is rolled evenly and adjusted to the same line.
What can be said about parting:
After rolling the top coat, it turns white when it rains. Why is that?
Liu Sidong, Meihui dealer from Linyi City, Shandong:
Analysis: This type of problem can be divided into the following three situations:
1. The paint film has not completely vitrified, and some capillaries have not fully cured. A large amount of rainwater washes over, causing moisture to seep into the film, resulting in whitening and softening;
2. The solid content of stone texture paint is high, and the paint film is thick, leading to extended drying time.
3. The paint film is surface dry but not completely dry.
Recommended solution: 1. After spraying the middle coat, let it sit for 2 days before applying the top coat. The environment for applying the top coat: low humidity weather, temperature not lower than 5 ℃.
2. If this situation has occurred, it will naturally disappear after sitting for a while and will not affect the quality.
In this issue of "Getting Close to Meihui", we first answer the above three questions. Congratulations to the two dealers for their active responses and the three friends for their enthusiastic questions. You will receive a beautiful gift from Meihui.
