I am pulling my hair out. I had a bedroom and bathroom constructed in
my basement. 5 days after the drywall had been mudded and sanded I
put on one coat of Kilz Oil based primer. The next day I put on a
coat of satin latex based Behr paint on the ceiling. 1 day following
the ceiling paint I used Behr Bed and Bath paint on the walls, WITHOUT
cutting in, I was leaving the cut in for last (doesn't make sense I
know). I followed that up the following night with a second top
coat. The second coat was applied pretty thick with a 3/4" nap. That
night I left a window open in the basement to help alleviated the
smell. It got down to 45 degrees that night and I had 65% humidity in
the basement. When I checked the bathroom the following morning there
was sweat all over the walls. There was even a small amount of sweat
above the shower where there would be green board (the shower has
never been used). That's my first mystery. I let the room sit for two
days without touching it. After two days I went to remove the tape
and the layers of top coat peeled away in many areas when I tried to
remove the tape. The walls felt like they could have been a slight
bit dusty underneath. I'm trying to figure out what caused these
issues and what I should do next. PLEASE HELP!!

Hi,
Holly cow! What's the rush? Oil and Latex? I don't get it.
For me using anything oil is thing of past! No exhaust fan in the bath
room?

Kilz I believe is a lacquer, I've used it many times on walls mostly
stained it keeps the stains from bleeding threw. I have never had a problem
putting latex over it. On a newly taped wall usually you use PVA to seal it.

I'm wondering how bad it is really peeling. If the chips are big, like
fingernail size or bigger, then I'd say you have adhesion problems.
But even the best paint jobs will chip when you pull the masking tape,
if you leave it on too long. Masking tape should be pulled as soon as
possible. You should also score the cut line with a razor knife,
especially if you have waited too long before pulling it. Really, pro
painters don't use a lot of masking tape. It is better to cut with a
brush.

As for the condensation, that happened because paint introduced a lot
of moisture into the air, and by opening the window, the air got below
the dew point. Shouldn't really cause any problems provided the paint
was dry to the touch before water got to it.
