My house is undergoing a remodel, and was recently stuccoed and painted. A few weeks ago, I leaned against the house with my foot as I was talking to someone and when I pulled my foot off the house there were little white areas as I had pulled stucco off the house. Fast forward a few days and I bumped the house with some wonder board, again a little white patch showed. These areas now have be touched up. Is there any way to correct this, it appears that too much sand was added to the stucco. When my wife asked the contractor about it he said we should have added color to the stucco but we chose not too. As this were our fault because we wanted a color that was not on the stucco color chart.
House was painted with a spray gun, if that is important. Any advise would be appreciated.

What was the time frame between finishing the stucco work and then painting. Also was there a primer used that bonds to cement.
From stucco to paint was about 24 to 48 hours, maybe a little longer depending on where they finished one and started the next but there was not a lot of time in between. A primer was used but I do not know if the primer used was for bonding to cement.

Stucco was still too wet, the primer and/or paint did not have a proper substrate. Tell the contractor he has to strip all the paint off ... that won't be difficult ... and repaint the house when the stucco has cured."Put your creed in your deed." Emerson

24 to 48 hours? I can't believe people do that stuff.

What is the proper cure time for stucco?
Normal summer weather dry and hot 30 days to both allow the moisture to dry and the chemical reactions to stop. Add moisture and cooler temperatures it could take 4+ months. Then I would slightly acid wash the stucco to neutralize any alkaline ph. Then wait one more month and then paint.
What is the proper cure time for stucco?
Best Practice:
28 days wet/moist for the scratch coat, then brown coat and another 28 wet/moist days. Of course, that's only followed on large, educated client jobs.
Then; Depending on the weather, a couple of weeks after the last coat for drying before painting.
Ps: Your contractor is/was a hack.

I'm always right! Except when I'm not.
I have never seen 28 day cure time for the scratch coat. Usually about a week."Put your creed in your deed." Emerson

Government spec in CA.
Also 28 moist days is concrete 98% cure time.
28 years =~ 99.9? % cured.
'Crete in the Colloseum is probably 100% cured. =~2000 years.
Better cure in scratch coat = less cracks in Brown coat.
Better cure in Brown = better waterproofing.
