Kathy - most importantly - make sure your painter does a PH test on that stucco before he or she paints it.
The PH needs to be below 13.0 or you could have what is called a burn - best it will discolor your paint - worst - it will come off!
My best advice is to make sure that your painter is using the best 100% Acrylic XT paint that manufacturer produces. We all have our favorites - and painters are notoriously dedicated to their brands!
