This is the wall in my apartment, near the head of my bed, that's been destroyed by an inner-wall leak over the last two days. Tragic. Next step is either getting my building to replaster and repaint (how do you match paint colors anyway?) or drying out the wall (somehow) and repainting. I'm afraid I'm terribly un-handy with these things, so I've been Googling up a storm. My main concern is preventing mold from developing as a result of the damp. Would it be inadvisable to slather my wall in Purell?
