Great Stuff seems to work.



And who said you never give helpful answers?

Likely you have never even tried it because great stuff isn't UV
resistant so it quickly turns yellow and gets brittle. Other than that
it looks great on those infomercials.


I have tried it. Six years ago to fill the voids around a new circuit
breaker box. It's still there.

In the event it does turn brittle decades from now, who cares? Bricks are
brittle. As long as bricks, or Great Stuff, are not under shear stress,
brittleness is irrelevant.


Absolutely relevant for the application. There is a really valid reason
why certain methods become standard methods.
