If you are from the countryside, you have learned the relevant contents from your parents at home, and you have the skills of plastering and wall plastering. You can repaint the mottled facade with putty powder. If there is no relevant technology, you can buy some wall latex paint and brush it again, so that the mottled wall becomes clean and flat, and it will not cause dust to fall down.

But latex paint is still harmful to human body, especially since we have to stay in this dormitory every day. Once the wall is painted with latex paint, the living time is short, which is likely to lead to the spread of formaldehyde, thus causing health problems.

So the best way is to cover it with posters and wallpaper, which is the simplest and cheapest choice. All the mottled walls will be sealed, which will look more pleasing to the eye, more personalized and outstanding.

Or use posters, the cost will be higher, but it will highlight your personality. Others will be attracted by it, especially the senior sister who comes to inspect the dormitory. Seeing this scene may interest you a little and give you a chance to strike up a conversation.

Besides, if you really don't want to spend money by yourself, you can also tell the housekeeper that the wall beside your bed is a little dusty. Can you ask the master to repair it?

In addition, the school will carry out a major overhaul during the summer vacation, and will go to each dormitory to ask questions before the repair. Such as air conditioning, washing machine, light bulbs, etc. , as well as locks and windows, all kinds of things. In short, we can report this when we register this, and then there will be relevant personnel to repair it.

However, this will take a long time. Generally, after a holiday, if you will change your dormitory during the holiday, you don't have to bother. Let's put up a wallpaper. In short, there are many ways to deal with it, and the key is yourself.
