I still haven't bleach cleaned the other sides, yet to be painted. But the results are so much nicer, when it's all done. I've used textured paint, so it's covered a multitude of cement sins. Just normal wear and tear. I've spent close to a grand on paint. More than I thought I needed, or wanted to spend.
I consider it an investment however. Which I'll share more about, when I finally get this job finished. It always takes longer than I think!
