Hello,
I am currently setting up my apartment and want to mount the TV on a wall. I drilled the first hole but I’m not sure if the wall plugs are suitable, as drilling was relatively easy.
Based on the drilling dust, it seems to be gypsum (see pictures). However, the wall does not sound hollow and is about 25cm (10 inches) deep. What material could this wall be made of? And will standard plastic wall plugs work in this type of wall?
Thanks and best regards

How about getting a "stud finder" that detects different materials or their position inside the wall? 🙂That would be a bit expensive just to drill four holes, and you usually assume that a wall is free of foreign objects anyway.S

- Check the building plans – none available.
- Use a cable/stud detector – too expensive.
- Carefully drill/scratch and check.
The much-mentioned crystal balls, like many other essential building materials, are currently in short supply 😉

First, I would make sure that there are really no cables or pipes running through the wall! So a cable and pipe locator would definitely be helpful. I always use mine to be on the safe side (I once drilled into a power cable – so I know that no matter how careful you are, you can still hit a “direct hit”).
If you have a TV mount with multiple mounting holes, you could probably do without one screw. I can only advise using proper wall plugs suitable for your wall type (for example, something like fischer Duopower).
