I'm hoping that somebody will be able to assist. I have a bedroom wall with decent plaster on, so I filled the few gaps/cracks, and then put on my primer - ready to paint the wall red.
Unfortunately this is what has happened:
The filler is showing through the primer, and the rest of the wall is patchy/runny. What can I do? I don't really want to add the paint now if it is going to look like this.
Any assistance/advice would be greatly appreciated!
