One last drywall Q -- sealing to brick - Aram - 07-09-2016
Thanks for being patient with me. I got the fire resistant drywall screwed in under my stairwell, tape and mud done -- but how do I seal the edge where drywall meets brick? Some kinda caulking, or...?
Thanks,

I'd use paintable caulk if you're worried about air sealing, I'm not sure i would be, and then cover it with a trim board.

Usually a J bead or L bead is used if the brick is fairly straight. You may be able to slip an L bead behind the sheet rock.J bead is installed on the edge of the panel before installation. I would try to slip an L bead behind the pane,it will not slip in if there are screws in the way.
If you hit a screw an indentation will show up on the hidden edge, cut a piece out of any places a screw may be. Then the bead will slip in .You do not need to fasten J bead or L bead in most cases.Make sure if you do use a bead that you get the correct thickness.1/2" & 5/8 " bead are available in aluminum or vinyl.

Why are you sealing between the brick and the drywall? Appearance or a fire rating? I assume a fire rating since you are using fire-resistant drywall. In that case, whatever you use also has to be fire-resistant. There's fireblock expanding foam but that's probably not what you want.

Fire rating.
It's an under-stairs storage area and not visible.
Also, LIL, thanks everyone who answered so far.

Your local Borg should have firestop caulking. It will remain flexible.
