Painting Concrete

Today's chore was to paint the concrete in the back of the house.  It was looking pretty bad and the rough texture of the concrete was a magnet for dirt and the growth of mildew.  It required power washing about twice a year to get all the gunk off of it.  It should be much easier to maintain now.  I painted this concrete 12 years ago but it pretty much wore off after about 8 years.
