13. The Popcorn Wallpaper (Raufaser)

I mentioned it previously in my rant about the bathroom but let's dive into it.
Because, it is such an eyesore.
It is so ugly, but in an apartment intended for rent, it is of course such a cheap way to mask all irregularities on a wall.

It can hold, from what I have read, 4 or 5 layers of paint, mandatory feature in Germany because all tenants must repaint all the walls when leaving the apartment. Some layers can be several decades old.

Other types of patterns exist, but it seems that (probably only) in Germany, the ugliest one persists and found favour with this country, because in France, most walls that are covered are covered with wallpapers / sort of canvas that are painted over, but the patterns are more discreet, subtle and nice like Chevron (herringbone pattern).
Cheap is not necessary synonym with Ugly, right?
Of course, it is not!
