How would I paint a bare concrete outdoor water fountain?

You might also check the marine paints for below the water line. Don't know if it works on concrete but some of those boats are ferro cement. I know Rustoleum has 1 quart cans of it.

Yes, I saw both of those. I sent a note to Rustoleum and they replied that they didn't have any paint they would recommend for the inside of a fountain. The SF gate info vaguely states "oil based latex" but I've seen otherwise in other places. It's frustrating! Thanks for the help though.

thank you, I will look into that.

what paint? I did find some pool paint but it only comes in pool colors. Don't think we want a bright white or blue fountain. Did you find something else?

Called the company that makes it, not for fountains. Too bad, it looks great!
