Lines on wall in updstairs bedrooms

[boxtree]

Hi,

I've noticed that the bedrooms have 'lines' on the walls.... I think that this might be the timber frame inside of the wall showing through the plaster? Alternatively it could be where the plasterboards are joined together? This is in every room upstairs but not downstairs.


Is there anything I can do to fix this? It is very ugly. I was wondering if it was as simple as screwing the plasterboard back onto the wall?


Sorry for the quality of the picture but it looks much worse in real life and it visibly sticks out.

It's been taped, sanded and painted. It needs skimming (plastering).

Thank you for the feedback.

Does the whole wall have to be plastered or just the lines.

If I push on the lines it goes back toward the wall, like the board has come away from the wall. Can I not just screw it back onto the wall?

I'm looking for a DIY approach if possible.
