I purchased my home with pool in August 2013. The previous homeowner had installed concrete rockscape around the pool 3-4 years ago. This includes planter beds, pool deck, columns wrapping the patio cover and the pool waterfall. Anyways, it looked nice (and freshly painted) when I bought, but a year later the paint on the rockscape surfaces has started to deteriorate significantly and patches of "white" (the paint color was a sort of medium caramel) are showing everywhere. I've never done much painting of outdoor concrete surfaces but would like to try vs. hiring someone. Does anyone have any experience with painting large outdoor "rockscape" and pool deck surfaces? What products seem to work well and "stand the test of time"? It appears the existing paint was sprayed on (based upon the multiple areas of over-spray), but can it be rolled and brushed on? Could probably get access to a decent paint sprayer if I had to. Thanks in advance to anyone that can help out with guidance and advice.
