So I'm wondering if our problem is more due to inside moisture in
summer than seepage from outside which we would be able to fix by a
dehumidifier. Can this result in effervescence?
Doubtful. "Effervescence" is a quality of bubbly-ness in your
soda/champagne. Or a really perky person. "Efflorescence" is a result
of hydraulic pressure from behind a masonry wall.
I would also like
to fix up the walls but it will be near impossible
and certainly a major pain in the back to scrape the walls to bare
masonry. I was hoping to just paint over but have heard conflicting
reports how to do this. Being that the majority of the wall surface,
approx 90 percent has paint, I plan to scrape the peeled areas and
they cover with primer and they latex paint. However I heard that you
don't need to prime masonry first?
You'll definately want to wire brush the loose stuff off. I'd get a
can or two of Dry-Loc and follow the directions.
Yer welcome. Tom
