In the end, the work performed was acceptable, but getting there required a lot more supervision and quality control work on my part than I would have preferred. For our project, we chose to have a stucco over-coat applied to our original stucco instead of painting it, partly to ensure a texture match but also because bare stucco would not have to be re-painted in a few years. The stucco over-coat developed a mild blotchy pattern after the painting. Approved Contractor consulted the stucco manufacturer who advised the discoloration was probably due to the stucco getting wet again before it was completely cured. They acknowledged that it was probably caused by their paint crew power-washing the eaves too soon after the stucco was applied. Their recommendation was to paint over the stucco to achieve a uniform color. We declined because we think that even with the discoloration the stucco will age better than paint (the reason we paid extra for the stucco overcoat in the first place). I feel bad for them, since there doesn't seem to be any other practical remedy that would work for us. But I hope they have learned how to avoid this problem in future projects.
