OK,
i've notice that some folks are jumping to conclusions that I did not read in Mike's ariginal post. Mike, tell me if I'm wrong or right.
First and most glaring. calcimine - although the bane of our existance here in Mass, Mike said it was blue board and plaster. although the house was built, in the 40's (hay-day of calcimine ceilings) it sounds like this ceiling was installed in the 60's - 80's (just a quess) I'm saying, no calcimine.
Second, my good friend PWG implies Kilz is a big Z product (correct me me if I'm wrong about that assumption). Just because it has a "z" on the end, don't make it a "Z" product. kilz is made by Masterchem Industries, Inc, .... and they lie also.
BUT, I 100% agree, kilz is not intended to be an all-over primer (i think that is on the can - or it used to be)
Third, another comment was made that there was poor adhesion to the 1940's plaster. Other comments made about layers and layers of paint in a 60 + old bathroom. Again, blueboard and skim coat - not 40's materials. AND Mike is talking about the PVA primer coming off the JC that was applied over the Kilz.
Plus other comments.
Hey, I could be wrong about what I read, but I did read Mike's original a couple of times.
My take ? Kilz was innappropriate all-over primer.
AND, I've NEVER liked PVA primer. Never trusted it. I know that's an arguable opinion, but it's mine.
I think the steam from the shower migrated through the PVA and re-wet the JC. I know an overly simple explanation - but usually the simple answer is the correct answer.
About 5 years ago we had moisture, steam, peeling, mold problems in our bath. I washed (bleach and water), scraped, sanded, and patched (all purpose JC). Applied two coats of Zinsser Perma-White. The ceiling is still in excellent shape (knock on wood) - and I'm no Zinsser fan, so I would not promote anything of theirs out of loyalty. They should have stayed ONLY in the shellac business, IMO
