How to demolish an interior aerated concrete wall as dust-free and simply as possible?

If you want to keep a piece of wall at the top, I would build it afterward with studs and plaster. It's a good idea to have a "stop" at the ceiling to prevent cooking odors from spreading throughout the room.

Yes, it's a good idea. Since the meeting between the wall and ceiling is a soft plastered impression of stucco, it would be nice to keep it, but it might risk falling down and being difficult to arrange.

Otherwise, I was thinking one could attach a board, see image.

Count on the fact that the inner wall is not securely fastened to the ceiling to be preserved. In my 1936 apartment, the only securing of the inner walls to the ceiling is four-inch nails driven into the ceiling, bent, and coated in mortar.

It is better, in that case, to tear down the entire wall and then build a drywall-clad framework structure attached to the ceiling and walls. The vaulted ceiling angles you have now can be recreated with gypsum plaster against the ceiling and drywall.

Expect that the interior wall is not secured tightly enough to the ceiling to be preserved. In my 1936 apartment, the only securing of the interior walls to the ceiling is four-inch nails driven into the ceiling and then bent and coated in mortar.

Better in that case to demolish the entire wall and then build a drywall-clad frame structure attached to the ceiling and walls. The vaulted ceiling angles you have now can be recreated with plaster against the ceiling and drywall.

Awesome! Thanks for the tip!

How did it go tearing down the wall? Do you have any advice? I have a similar wall to tear down and discovered that it's made of slaggplattor.

Hi! Sorry for the late reply, we tore it down with a demolition hammer, taking down slaggplatta by slaggplatta. It went well, a bit of dust, but we sprayed with a plant sprayer to quickly bring it down to the floor (which was covered). How did it go for you?

Perforated a 20x20 cm area and then went at it with a hand sledgehammer. Dusty as anything! Stood by the window from time to time so the neighbors wouldn't think there was a fire. Now the wall is gone and I've got a taste for more.

Perforated a 20x20 cm patch and then used a hand sledge. Very dusty! I stood by the window every now and then so the neighbors wouldn't think there was a fire. Now the wall is gone and I've got the taste for more.

Haha, yes, doesn't it give you the taste for more?

Haha, ja, isn't it addictive?

Hi Oscar, how did you manage up against the ceiling, did you save 20 cm or was it impossible to save so it just fell down like that?

Hi Oscar, how did you manage up to the ceiling, did you save 20 cm or was it impossible to save so it just fell down, you know?

I cleared everything all the way to the top.
The issue was that years of paint caused the wall/ceiling to "stick together" due to the paint, and chunks of the ceiling paint peeled off.
If I were to do it again today, I would cut into the ceiling concrete so the ceiling paint wouldn't come off.

If I had retained a part of the wall against the ceiling, I would have made a cut before I started tearing down. Then the cut needs to be staggered so you don't end up with remaining wall over your head.
