If you want to use shellac try Zinsser BIN. Its a shellac based sealer
that will give it a bright white finish.

Any ideas on how to paint celotex?
The shop I've inherited (on the corner of our lot) was finished with
celotex. I've tried painting it, but it is really absorbent. Also, where
there had been water leaks from the ceiling, the celotex is discolored,
and
paint doesn't cover the stains.
My intent is to paint it white to brighten up the shop. I've been using
a
brush and roller, and I'm considering spraying paint in the future.

Shellac. Give it a good coat of shellac. You can then paint over the
shellac and the stains won't bleed, or at least not as badly.
