Plug that does not hold

[leosoleo]

Hi, I've messed up a bit and I'm not very knowledgeable.

I put up a type of plank on the wall, and in one of the holes I made, the drill just went right through (probably concrete walls, I think, apartment from the 40s) while the other two holes required some effort with the hammer drill. In the hole where the drill went right through, I noticed after I attached the plank that the plug doesn't hold. So it's just two of the screws holding the plank, and the third is, so to speak, loose and just spins around when you try to screw it in. Is there any way to get it to hold without having to unscrew everything again? The other two are already tightened, and it feels a bit tricky to have to remove those plugs again, etc...

sounds like you've drilled into a plastered brick wall. In one of the holes you drilled, you probably hit between the bricks, hence the feeling that you flew through. Old plaster is not very good for anchoring. Try drilling a new hole so you hit a brick. Then, if the plug still sits poorly, there is a special 2-component compound that you mix and press into the hole before inserting the plug. Once everything has set, you'll get significantly better "pull" when you screw in.

However, I don't remember the brand of the compound, but most well-stocked hardware stores have it.

Plastic Padding usually works.
