Blistering, flaking and salt-pushed paint each mean something different. Read the failure first, because repainting the wrong one is a waste of a weekend.
Continuous drainage done right, including the air gap rule that explains the commonest failure and the places you are not allowed to send the water.
The measuring method, the right soil, and the clearance limit that decides whether you can fill at the wall or have to cut at the far end.
