Default Painting an exterior cement block wall

I have a wartime house and at some point the cement foundation blocks that
are above ground were painted. I have owned the house for 16 years, so it
was at least 17 years ago, but probably more like 25. I bought the house
from a couple in their late 80's and the living room wallpaper was a scene
of a golf course (circa 1960 something). Anyway, the paint is starting
to peel and chip from the cold and snow.
Should I paint it again and if so with what kind of paint?


When our Florida condo was painted, the contractor used acryllic latex
paint, which is standard for masonry. The pressure washed below grade
about six or eight inches so as mortar absorbed moisture beneath the new
paint coat, it would be buried and not show peeling. They applied a
bleach solution prior to p.w., which didn't make a lot of sense, but the
job turned out wonderfully and lasted. For hairline cracks, they used a
brushable caulk, then one coat primer and one coat paint. They had rec.
two coats paint, but condo went for lower cost and the results could not
have been better. The previous paint job was poorly done, with loads of
mildew (no prep) under the peeling paint.
