I have a customer who wants me to spray some type of silicone coating onto her stucco. I seem to have read somewhere that you should’nt do this. Any info?
Thanks,
Charlie

Seems to me you'd be risking sealing water vapor in the stucco which could cause it to deteriorate (e.g., spall during cold weather.
I don't know this for sure viz a viz stucco, but it sure is true for other masonry veener products (e.g., brick.
There might be a masory sealer which you could use, which supposedly allow vapro to pass thru but block liquid water.
