Some weeks back I woke one morning to find a large flake of spackle(?) had cracked and almost come completely off the wall in my apartment entrance:
According to the board of our housing cooperative there have been multiple reports of similar damage in other apartments, and it seems the building suffers from some foundation shifting.
Behind the flake the wall seems to be solid concrete. Here's a close up of the flake material from a small piece I broke off:
Looks like it's just paint on spackle on old newspaper?
I have never done much DIY work before, so any advice on how to repair this would be greatly appreciated.
My initial thoughts would be to:
- Carefully remove the flake and any loose bits around it (hopefully avoiding having to remove the clothes rack).
- Fill in the hole with some flexible(?) spackle (there may be more movement in the building foundation in the future)
- Paint over
