Technical term requested (for translation)

I am currently translating a text into German, in which there is a word I do not know. Maybe an expert from the forum could help me?

It is about the ceiling of a room that has a crack. But this ceiling is covered with a paper that was then whitewashed. And this "paper" or fabric is torn.

What is it called?

In the picture attached, you can see exactly what I mean.

Thank you very much for any help!

That will be painter's fleece

Or wallpaper. But just say the word in the language you are translating from!

Thank you very much for the answer. The word is "biasi" in Georgian, but that probably doesn't help. In any case, it is a classic, multi-story building, the story takes place around 1960, a subway is being constructed under the building and the walls are cracking. At one point it also says: This "bsari" is cracked - as can be seen in the photo from the film based on the book. Maybe it really is simply wallpaper? Ceiling wallpaper? Or a painter's fleece? I am also sending another photo. Thank you very, very much!

Please write the word again using the Georgian alphabet.
