Hello everyone,
As you can easily see in the pictures, I have a lot of electrical cables that required corresponding chases. Now all the cables are in place, and I need to close the large recesses, especially the big gap at the rear right in the picture.
Should I use the usual patching plaster (such as Knauf Rotband), or are there special materials that are more flexible and less likely to develop cracks over time?
To bridge cracks, I will of course incorporate fiberglass mesh or similar reinforcement.
It is also important to me that the filling material is strong enough to restore at least some structural stability to the masonry, which I don’t expect from Rotband.
Could I possibly use masonry or plaster mortar, or even cement mortar for this? Are NYM-J cables allowed to come into contact with these materials?
Thank you in advance and best regards,
Scami

I don’t see any problem with data cables laid parallel to the power lines. For me, it would be an issue if they weren’t installed so they can be replaced. I would always put them inside a conduit.You are absolutely right in principle! Since I don’t want to cut any more or deeper grooves, I’m accepting this compromise. The applicable standard (DIN) also requires empty conduits in this case, but I prefer not to implement it.
However, where I will definitely use conduits is for the route between the door intercom/motorized lock and the distribution cabinet.

....and don’t be surprised if later on some LEDs blink/light up even though they are switched off...So, do you install wiring to light fixtures in a separate conduit? Please enlighten me.. What if I operate decentralized actuators in a KNX system.. could they still light up then? 🙂)
