I do want to do the sides..at least the parts that are showing. Our Patio is stained and stamped, so I don't really want the gray showing on the sides. The additional piece that I would like to do is with the sides of the house that the poured concrete walls are showing by the patio area. Right now I have Hardi board siding, but it doesn’t come all the way down. So in some areas I do have some gray areas which I would like to paint using the same paint from my house. It sounds like this might not be recommended…so any advice on how to do that part too would be greatly appreciated!
