I had my roof replaced last November. There was around 40 feet of stucco

flashing where the roof met stuccoed vertical walls on the second story.
Some companies do a double layer of stucco, but my contractor did one.

The contractor told me I should prime the new stucco after a month or
two. I did some research and evidently you use a special primer for
stucco. But people said you should paint after priming. So far, I've
done neither. Rains will start in a few weeks, maybe a month, maybe
longer I'm not ready to paint the whole house exterior (two story, 1925
square foot). Should I just prime and paint the unpainted stucco anyway
(use some innocuous color topcoat, water based) in the mean time? Thanks
for guidance.

It strikes me that the prime coat has to do with paint, not stucco.
I would check with stucco manufacturers.
They want their product to work and have tech staff to deal with
questions like this.
