Should I paint the walls or install the doors first when decorating the house? Why?

You should install the door first, and then paint the wall. The main reasons are as follows: when installing the door, use tools such as chainsaws. If you have painted it, your wall will be dirty. When installing the door, there will be doorways, basic blockboards and other materials Those materials are long and hard. If you are not careful, you will break the wall. Although the wall can be repaired, there is a certain gap between the wall always repaired and the wall made at one time.
