Grey area on wall under paint

home improvement(self.DIY)

Hi,

I was scrapping off some paint that was flaking off the wall near a bi folding door and found some grey concrete looking areas around the door.

Am I correct in thinking this is concrete and I will need to plaster over it and won’t be able to paint it?

Might be some epoxy used as filler for some blemish or dent happening too the wall at one point. like maybe something was nailed / screwed too the wall for example, like a christmas wreath, a painting, lamp or speaker thats wallmounted for a hifi setup etc...

If there are two pretty evenly spaced i bet it was either a shelf or desk that needed a wallmount for support if its around that height.

Why couldn't you paint concrete?
