I am adding some decorative masonry block to my stucco home. This is the
heavy troweled type stucco finish. I notice today that some of the work

water in the mix...or too little...or maybe something else.

I'm no stucco expert but the first thing I'd suspect is too heavy of a
coat which could cause uneven drying.

The same might be caused by the substrate sucking the moisture from
the mud too quickly.
