Okay, then it's probably best if I ask him to talk to the association. Thanks for the detailed response.J JohanLun said:From the 1920s, it's probably thick lime plaster that can only hold a very light picture with a nail (no plugs), and underneath this, I would guess, are solid wood or brick walls. I would continue drilling and find out what the wall is made of. Even better is probably to ask the board in the association as they surely know the wall's construction.
As I said, the plaster can't support anything heavy, in my experience. In any case, not an Elfa system or a TV set. But in a 1920s house, there's definitely something behind it that you can hang anything on. Not like 1970s houses with simple plasterboard followed by air or blue concrete. Back then, they probably thought the heaviest thing to put up was a pinned-up picture from OKEJ with Samanta Fox.
We had similar problems when I helped my son change his kitchen. No matter how deep we drilled, it only turned to powder. The plug just spun in the hole.
I resorted to anchor mass. It held well.

If black dust is coming out, it's probably slaggplattor, drill for my 8 mm plug and insert a 10 mm plug, thin wall difficult with fastening, thick wall drill so deep that the bottom stops about 2 cm from the other side and plug with 2 plugs if possible (otherwise cut a plug) the plug is tapped in with a hammer.
