Had a call from the electrican a few days ago. He was moving a house’s panel and needed a basement lathe and plaster ceiling torn down ASAP, and the client wanted the exposed floor joists vacuumed and sprayed with a stain blocking primer. No big deal, “Here’s the price.”
We were a little surprised to find some fire damaged floor joists reinforced and rebuild back sometime when knob and tube was still popular.
I’ve said before how nice the waterbased Kilz2 is to work with and 5 gallons was shot in two coats yesterday. I showed up this morning to vacuum the floor and the entire basement smelled like a dank smoldering camp fire after a midnight rain. It was really bad, much worse than if nothing had been done.
Apparently the Kilz2 transmits smells from fire damage quite well.
10 hours, a few gallons of BIN and the problem went away. An expensive lesson.

That's interesting
I've used the white pigmented shellac (bin) for the same application as you, but would have thought that the Kilz would have done the same job. Apparently NOT. I've always found the Bin a pain to work with, (kinda watery, messy) and WOULD have been tempted to use the Kilz.
Thanks for the heads up.
the kilz has an odor to it till it dry. might just be the paint. it smelled like mildew rotten eggs..A man is a success if he gets up in the morning and gets to bed at night, and in between he does what he wants to do...

The house smelled like a smoldering campfire after a rainstorm passed over. The clients admitted to being alarmed in the morning when the smell was strongest and checked to make sure the house wasn't on fire!

It was the latex kilz2, not the regular stuff. I still like the kilz2, but not for this application. :-)

There's two kinds of Kilz. You must have used Kilz2, which is a latex primer. I use it for paint issues.
I liked your "second" choice. Bin is great for really "sealing in" stuff like fire or dead dog/cat/ferret smells. Don't ask how I know...

What Karp said. Use Shellac. It's the only primer that will hold the smell down, unless you use three coats (three days) of oil-based primer.
Zinser's BIN is a white-pigmented shellac that will work well. But any of the clear shellacs would do just as well.
But remember that shellac is alcohol based. Be sure that you use ventilation, and be sure that all pilot lights are out. And no smoking or lights.
It will probably take 3 or 4 coats to hide that smell. The good news is that a coat usually dries in about 15 minutes.
Support our Troops. Bring them home. Now. And pray that at least some of the buildings in the green zone have flat roofs, with a stairway.
And no smoking or lights.
How do you see without lights? Just kidding.
For ventilation I've been having great results with a portable dust collector without the dust bag. 30' of 4" flex hose reached down to the basement and created enough negative pressure in the surounding rooms that the client couldn't smell the BIN at all.
The dust collector also works great to vent dust from rooms. In the two years I've had it the bag rarely gets used since it cuts down on air flow so much.

Always oil base Kilz or Zinser.
Im working on one now.
Latex is porus. Oil is not .

we had the same problem years ago with a spray-seal job done with latex.
had to be re-sprayed with oil.
we don't spray BIN very often.
too many clogging tip issues

After the first go around I finally invested in a 36" extension and swivel attachement to change the tip angle to reach around corners and wow did that make a difference in speed, not to mention it was much cleaner for me.
