Hello everyone, we originally planned only one ceiling connection in the dining room, but now we want to install two ceiling lights there. The idea is to have the lights hang over the dining table, one over each half. We are looking for a way to achieve an elegant and stylish cable management. A standard plastic cable conduit is only an emergency solution. The ceiling lights have already been chosen. They will be the Ikea Hektar. Best regards, Alex

I just took a look around the apartment I’m currently in. The plaster on the ceiling is about 15mm (0.6 inches) thick...

Exactly, concrete priming – even so, it wasn’t a pleasant sight.

But the question remains... why use precast concrete slabs then? Of course, I’m not a construction expert, but I have seen quite a few buildings. And everywhere, only filler was applied – you can often read that, as it’s a completely normal task for the painter.

Isn't 15mm (0.6 inches) also very tight to properly install a cable there? Otherwise, prisoners have managed to dig escape tunnels through hard materials, although whether this is practical for cable installation is another question...

According to proper standards, you are not allowed to chase channels in concrete. If there is plaster, I would simply install it WITHIN the plaster, as this minimizes damage.

Using a flat cable is no problem under the plaster (this was how wiring was usually installed on the ceiling in the past), especially if it’s just a short section.

By the way, in our case, the painter did not take care of the ceiling. It was quite normal for the plasterer to handle it. It wasn’t even a question and was also very cost-effective. We don’t have precast ceilings but rather traditional formwork. However, as mentioned, I also know this with precast ceilings. No filling or sanding and, if necessary, leveling out any offsets—just plaster it over and that’s it.

Yes, with in-situ concrete, it also depends on the formwork used. And of course, that’s not done by the painter.

You’re writing as if it were easier this way – but it’s not. You still need to apply filler and sand a plastered ceiling if you want it smooth. Or are you trying to tell me that the plasterer delivered that surface perfectly smooth right away?

As I said, plastering precast concrete elements seems to me a very unnecessary solution, and I still don’t understand the point of it.
