~1980 house is built of stucco over cinder block (in some places) and

There are long, narrow, noticeable cracks in the exterior stucco

Is it OK to just patch these cracks? Or, should we expose the
underlying
blocks to get an idea as to how much they've penetrated the structural
block?

If *just* superficial, any advantage to polymeric patches vs. (cement)
"stucco patch"?

And, if the cracks permeate the underlying block (presumably on mortar
lines), what's the recommended remedy? Anything "injectable"?
(fine mortar, cement adhesive, etc.)

Thx!

I would start out by looking at websites for a couple of paint companies
and look at the technical stuff for particular conditions. Read the
recommendations for product and application. Then, so you have an idea
of how one SHOULD approach the problem, get a couple of estimated from
reputable paint contractors. The better prepared you are, the less they
will try to over-sell and you might get additional good recommendations.

Some time ago, wasn't it discussed here about stucco painting vs. fogging?
I asked around about fogging here and no one seems to know what it is.
I think people get confused about different types of
stucco....stucco/concrete block is almost only thing used in Florida.
Stucco on lath, IDK. In Florida, it is also almost universal to use
semi-gloss acryllic paint. Semi to discourage mildew from clinging.
