What plaster/mortar? Interior wall damaged to the brick

[Galenskaparen]

Hello,

I'm trying to determine if repairing an interior wall is something I should undertake myself. I have plenty of enthusiasm and a lack of knowledge...

Situation:

• Interior wall in the bedroom, the plaster has come off in a corner, all the way to the brick.
• The wall is made of some kind of stone, I think it's a type of hollow stone or something like that. The properties don't seem to match straight-up brick when I've drilled into it...
• Area is about half a square meter
• I've never repaired anything like this before. I've only filled a few small holes with house fix

What should I repair with?

How should I proceed?



How did this happen? Well, an old ugly wall trim was glued so tightly that when I tried to cut and pry it off, the plaster started to come off... and once it started cracking, it was too late. FML.

Have I posted in the wrong subforum? Or is the question poorly formulated, or too easy? I don't think I can find any similar cases even though it should be very simple. Maybe I've searched with the wrong terms.

Search for plaster putty. It is the easiest for a beginner to fix plaster with.

Ok, thank you!

Got advice elsewhere that plaster and then some filler would suffice.

As above, use gypsum plaster, much easier!
