Uneven stress on the wall
Uneven stress on the wall is one of the main causes of wall cracking. In order to solve this problem, we need to do some "minor operations": first remove the cracks around the wall, then "slim down" the wall with a brick knife, put it in barbed wire and fix it, and finally scrape putty and repaint it, and the wall will be completely new!

Toya, the putty didn't dry during the decoration, which is one of the reasons for the wall cracking. Solving this problem is relatively simple: first fill the gap with putty, and then brush the top coat. As long as there is no color difference after painting, the wall is beautiful again!
