My bad. I didn't read close enough. Your right liquid nails would be best:embaresseBrads would probably have a tough time penetrating the brick. I think I would go with your first reaction and try liquid nails, just a thin bead so it doesn't squeeze out behind the ¼ round.

You could try taking something heavy, sitting it on the floor and then push it against the wall. That might help it stick to the wall better.
Larry, I knew you overlooked the brick part! I wish it would be that easy!
If I do use liquid nails, how would I "clamp" it to the wall long enough to hold it in place while it dries? Duck tape maybe? I'm talking a 20' run.
Thanks George and Larry!
This would be a great job for Dave's shop elves wouldn't it?
