As a result of Hurricane Sandy, some rain seeped through an upstairs
bathroom vent pipe collar, down to the bathroom ceiling above the shower.
After it dried and left a stain, I twice sprayed Kilz on the spot. I had
purchased a type of Kilz that blends in with the regular color of the
ceiling, so that you can't even see it.
Since then, whenever someone takes a shower, the spot has moisture from the
humidity/steam from the shower binding to the spot, until the moisture
dries. This isn't from above the ceiling.
What can I do about this - would simply painting the area solve this?
It may be from the fact that you didn't paint the whole
ceiling, just the spot. The Kilz must have a surface that
attracts moisture more than the regular paint. Also, don't
know if Kilz was ever intended as a final coat. I've
never used it that way. If it were me, I'd give it another
coat of Kilz, then give the whole ceiling two coats of
Thinking about this a bit more, here's what I suspect is
happening. It's likely unheated and cooler above the ceiling,
right? Kilz is designed to block, so it's going to be
impenetrable to moisture. If you have regular flat paint on
the rest of the ceiling, that will absorb some moisture.
So, the moisture hits the colder ceiling and condenses.
But you only see it where the Kilz is because the other
paint absorbs the small amount that's present.
Trader is right on. Repaint the area in question with a couple of
coats of regular latex paint and things should be fine. Did you get
up on the roof and repair the area where the leakage occurred?
Not yet, but that was a biblical event, 12 inches of wind-blown, directional
rain. It has rained normally several times since then with no evidence of
an issue. I will have the pipe collar looked at by someone. I don't go on
Have tem take a bucket of rooding cement with them and a putty knife
tospread it around with. Get someone you trust who will tell you the
honest truth about what they found. Someone looking for work can
always find something wrong on a roof, but what they find may not be
of any real importance.

Make sure they put the correct size pipe collar on because my leak was
caused by an incorrect size .... I think my repair guy said my roofer
put on a 2" collar which should have been 1.5" so I had a small leak
which I had repaired about 3 weeks ago. Today had a good rain and I
went in the attic to check that vent/vent pipe just below the roof and
it was nice and dry so things are looking good. Now I have to paint
that spot again.

I think you are 100% correct as evidenced right now on my wall. At
the time, I painted the brown stain with Kilz with at least 2 coats
and then 2 or 3 coats latex. It looked fine until now where I see
additional brown stains (perhaps 1" in width) just on the perimeter of
my original painting. My original painting still looks. So I suspect
your reasoning is correct and I didn't paint enough area. And yes I
had the roof leak fixed some time ago.
Probably not - I have the same problem in my hall left over from a previous
Painting - at least with a water based emulsion - simply allows the stain to
move through the paint.
I've tried spray on stainblock. I think I will try again next year with a
paint on blocker - or some neat SBR
which, once dry, is uttery water resistant - and paint sticks well to it.
It's become my favourite all time additive for mortar mixes and a general
"fixit" liquid - far more versatile than PVA.

Any of these choices should work......
1. Stop taking showers, or only take cold ones.
2. Cover the ceiling with ceiling tiles.
3. Replace the ceiling.
4. Replace the house
5. Move to another house.
6. Paint the ceiling black.
7. Put a picture or poster over it.
8. Require anyone using the bathroom to wear dark glasses.
9. Go blind.
10. Just dont worry about the stain, it wont kill anyone. There are more
important things in life to worry about.
