The neighbors kicked in and helped my stucco my home near Tampa. I saved even more money by mixing the stucco myself.
One of the neighbors is a painter for a living and told me that I shouldn't use anything other than Elastomeric. If you pour some of it out and let it dry it's actually stretchable. I didn't need to use any primer. I'm in Tampa Florida, so have similar climate at least as far as the temperature goes.
I had also just added an outside chimney on for a fireplace. I had to “overbuild” that to death. If the plywood moved, the stucco was going to crack.
For me it was a matter of simple luck, but if you haven't decided on a paint color yet I have a very helpful suggestion for you. You should consider a light tan, that is also a fairly good heat reflecting color.
Stucco does tend to get “hairline” cracks in it. If you have them match the color of the paint to DRIED light tan caulk you can make a crack vanish and only have to clean the caulk off of the end of your finger.
