Default stucco cracks

Help! My 18 month old stuuco is cracking. Cracks are horizontal at
about 2 feet on center and general alligator cracking all over,
especially at corners. Stucco is on galv. mesh on wood frame
structure. Mason (#$$!!!**^!!) used only 2 coats of stuuco (instead of
3) and topped it off with 2 coats of masonry paint. I had another
mason look at it and he said it was "horrendous". He thinks either
wrong sand was used (brick sand?) or mesh was stretched wrong. He
suggested elastomeric paint. I don't want to use the elastomeric paint
on the painted stucco because we have water problems in area as well
and I want stucco to breathe. I have been monitoring the cracks and
they seem to have slowed down. Should I patch the bad ones with stucco
patch and repaint or will cracks below just come right through? Remesh
and restucco with 3 coats???

Can't address the basic cracking problem, only covering. We have stucco
on concrete block, Florida. 40 yr. old building. We had quite a few
hairline cracks prior to painting by good prof. contractor. They used a
brushable caulk on cracks prior to priming and painting. None of the
cracks have reappeared, and the caulk doesn't telegraph through the
paint. We were told, for this climate, acryllic paint better than oil
for the breathability; have also read about the same. Our condo chose
to go with one coat of paint rather than two. Our old paint job was
horrible - didn't caulk around windows, probably didn't prime or clean
prior to painting. The old paint job had lots of blistering, with
mildew under the coat of paint, and lots of peeling. The "new" paint
job was done in 2001 and still looks great.

You could have major structural issues with your stucco. Stucco is not
waterproof and as water gets behind it must have an avenue of escape
(drainage). This has become a bigger and bigger problem in the past 10
or 15 years as homes have become more efficient and sealed tighter with
house wraps etc. Water used to dry to the inside of older homes but on
new homes it can't. As a result it will destroy stucco.

Start at this website to get the basics of stucco problems / solutions.
Good Luck

Parlallel cracks at two feet sounds like the mesh was not put up
correctly.
Water behind the stucco suggests flashing problems.
Water between stucco and wood frame promises rot.
I'm working with a contractor repairing that kind of problem and it is
expensive.
I would look for a forensic architect or engineer to document the
problem and suggest a fix.
