I have a spot on my wall where a significant amount of paint has bubbled up and pealed away revealing the plaster underneath. The total area is about 10 inches wide at the widest point and a couple feet from bottom of the damaged area to the top.
There was obviously a roof leak, and we've had our roof replaced so the leak is gone. Now I want to patch this area so it all ends up nicely finished and flush.
I'm assuming the plaster has now dried out and can just be patched/filled and brought flush with the rest of the wall. It's probably no more than 1/4" deep at the lowest spots where the old plaster is showing. And then it feathers out to surface depth (hope that makes sense).
What is the best kind of material to use for this kind of wall patching job? And what are the tricks to getting it on right so it looks like new again?
