I was going to put up a picture in our bedroom, as it is a large piece sized 70x100cm with an oak frame, so it weighs a few kilos, a simple nail felt far too flimsy.

I used some sort of 6mm universal plug from Clas Ohlson which, according to them, should work well in aerated concrete. Since the frame has quite a thick frame, I needed a screw that stuck out a little longer to be able to notch into the hanging bracket on the frame.

The problem, however, came when I screwed in the screw, fairly quickly the plug started to push out again and the drilled hole just widened.

I have now removed the plug and the hole that was initially drilled to 6mm is about 8mm wide and at the entrance about 10mm... So what do I do now? Is it best to fill the hole, if so how, and then drill a new hole and use a better type of plug?

You have probably drilled too shallow and when the screw reaches the bottom, it pushes out the plug.
 
then the screw is a bit on the thickest side, a 3.5-4 mm thick screw is sufficient
 
Drill deeper and insert a new plug and screw, problem solved.
 
The combination with a 4.5mm screw is good for that, as long as you haven't hit anything since the screw is 60mm long. But it almost looks like you have masonite as a wall? What's behind? How deep did you drill?

Certainly! The screw I intended to use was 30mm and was supposed to protrude slightly from the 28mm plug; the hole was undoubtedly drilled according to the plug's length :dizzy:

So how do I proceed to solve this mess?
  • Use some form of liquid plug, like Fischer Fill & Fix?
  • Use an even larger plug? Will it hold since the hole currently feels a bit uneven as it measures 8mm inside but 10mm at the outer part.
  • Fill the hole with something like husfix and then try to drill a new hole. Should I use a different type of plug then?

No, but I mean there's supposed to be a painting there. It won't be visible.

True, but we might move one day as well, so I think it's best to clean up right away :)
 
But if you drill the hole deeper, won't the plug fit? Alternatively, find an 8mm plug after you've drilled.
 
Just don't make it complicated, just go up a size on the plug if the hole is too large. I think spackling is unnecessary, you'd probably have to do it anyway when someone eventually moves out.
 
I agree with the previous speaker, but I do agree that at least the surface layer looks like masonite or something equivalent. So just a dumb question to double-check: Are you sure that's what the wall material underneath is?
