Bumpy bathroom wall

tdsmithj

One side of our bathroom wall is really bumpy and wondered what is the best way to handle it. There's places where it's higher by millimetres but you can easily see it with the paint.
Any help would be grateful.

You have to find out why it is bumpy first - by trying to remove the excessive plaster. I guess you'll find something unexpected underneath.

What sort of wall is it? Plasterboard? Bricks?

Is this an old house with brick walls?  It looks like the plaster has blown entirely (popped off the wall, hence the bulging) and needs replacing.

Its plasterboard. House is about 35 years old.

In which case it looks like someone is trying to break through from inside. 😳

I'd cut out the offending patch of board and replace.  Easier than messing around with the board, which does look broken.

I got the electric sander and looks like it's done the trick.

It just looks like very bad filling to me in which none of it was sanded down at all to a level finish.
