I live in an apartment building that has concrete/cement walls. I am still not sure which one it is. I included the image which has the wall in the background.
I would like to know which screws i should use to let's say hang shelves or paintings. Do i need to get concrete screws like tapcon and use an impact drive to screw them in? Can i just make a hole and use plastic anchors with regular screws? I did hang a picture on the wall but i had tough time getting the screws in with a cordless drill. Some of the wall chipped a bit.
Also are there beams behind the concrete wall or there is no reason to have them. I can just screw almost anything to it? I have a beam finder and it does detect some beams but i wonder if it's a false positive because it is a concrete wall.
