The stucco sub for my new home applied cement on a cold, windy day with temps dropping from 40 to 20 overnight. After I questioned him, he removed a lot of brown coat the same day and says he will clean remaining loose cement off the scratch coat before restarting. One portion of brown coat, however, remains. In that portion are two volleyball size spots that are soft.
Here are my questions:
If the remaining
portion is hard, is it okay to
Is the cleaned-off scratch coat probably okay as a base, if hard? (another couple of hundred feet). Should areas of scratch coat showing slight softness be stripped and started over?

What a mess… Thanks for your thoughts!
About the only way to make sure you get all
the frozen mortar off is with a hose or a broom. Frozen mortar is
powdery stuff which can
prevent a good bond. If you use a hose and the
wall is saturated, it may take days to dry out,
A couple of volleyballs aren't too bad so you may get by with just a good scraping.
I hope I never have this depressing experience
We had to scrape the whole side of a house when
the scratch coat got hit by freezing rain. I had a finish
coat pop off once several years ago when we put the finish over a
frozen brown coat .
The scratch coat is never as hard as your brown
coat, the fact is you may be able to scrape your scratch coat easily
with a nail (even in warm weather) and not your brown coat.
The give away on frozen mortar is the color- a dead body grey that you can spot a mile away. By now you know the color and should be able to detect it.
It sounds to me like everything is OK
except the volley balls. Tearing stucco off is a real real chore, and
it doesn't sound necessary.
