I'd be concerned that the brick may be deteriorated enough that it wouldn't withstand the high heat. It's also going to be a serious chore to remove the paint (which needs to be removed).
AquaBright will adhere to just about any surface.
Can you post some pictures?

I did not even think of the heat! This is an inside pool as well. Will that make a difference?
