HI Tony,
To seal the surfaces of old OSB or plywood I have used both the AFM product
that Chris has recommended and BIN Shellac, which is smelly until it off
gasses but does the job and is inert once cured...however this brings up
many more questions. What is in the walls behind the boards you are trying
to seal? It is just as likely that they are not airtight and that something
in the wall could be causing the reaction.
