Scrape and do it again.
Preventing blisters: construction is as important as maintenance
In order to prevent the wall paint from bubbling, it must start from the construction stage. Waterproofing must be done during decoration, and cracks should be repaired on the base of the wall. In addition, after decoration, the wall surface cannot be air-dried quickly, but must be dried in the shade to prevent the inside of the paint from being completely dry.
For daily maintenance, it is necessary to check frequently whether there is any leakage of the water pipe into the wall. If leakage is found, it must be dealt with immediately to prevent the water vapor from softening the putty and wall paint and causing the wall paint to bubble.

It is recommended to use elastic paint, and now many brands have introduced elastic film, which can more effectively prevent paint cracking.
If there are only cracks on the paint surface, shovel off the cracked part and repair it with the same color paint. Note that after the paint is repaired, the joints between the old and new paint must be smoothed with sandpaper to increase the aesthetics.
Anti-cracking skills: good environmental temperature and humidity control
Common wall cracks are generally caused by sudden changes in climate, which cause the wall to rapidly expand with heat and contract with cold, resulting in cracks. Therefore, in the changeable weather, the indoor temperature and humidity should be adjusted through the opening and closing of doors and windows, air conditioners, and dehumidifiers to avoid “early retirement” of walls.
