I took down some aerated concrete walls at home and read everything I could beforehand. It turned out that my 200 kr Jula reciprocating saw with the included blade cut down the wall and went through rebar without any problems. The blade got a little bent at the end but managed three walls, which isn't bad
Then I took gypsum and built up a nice edge on the outward-bent corners. It was a bit tricky, but it was quite okay in the end! The only mishap was a piece of aerated concrete wall that fell and made a small dent in the parquet, so my advice to others is to put some masonite board on the floor as protection and not just paper like I did!
