This morning we woke up and gave the boys a set of plastic gloves and a bucket with warm water. Their mission, in which they weren't given a choice - was to wash the walls. I can't believe how dirty the basement is! I went first with my bucket filled with TSP-90, when I got done washing the walls, the water in my bucket was a gross shade of brown.
The basement looks a little sad right now - dirty walls with lots of scars and dents, irregular concrete flooring, and sagging overhead lighting.
Next is wall spackling and floor sealer. See here for before photos.
