Had a water leak in the garage and I've got a wall with some damage about 6 inches up the side. What is the simplest way to repair this? I don't want to just cover it up, so I'm going to have to tear down the sheetrock and replace it? It's an area about 4-6 inches high, about 6 feet along one wall.
The wall is just plain sheetrock, painted.
