The plaster in my whole house which im doing up is in poor condition. Some of it has popper off the wall but most of it sounds hollow when you tap it with your knuckles.
If i hit it with a hammer a patch about the size of my hand will pop off the wall fairly easily.
Do I need to remove all of this to eather plaster or dot and dab
