We have wooden porch chairs that were supposed to be painted with outdoor paint but they have succumbed to some sort of mold. To repaint these would I have to sand/strip all of the existing paint & mold off? Is there a way to just prime the chairs and then paint over it all without fear of bleeding?

Note: I've tried removing the mold with every means I could think of (cleaners, bleaches, etc). It only comes off with severe abrasion to the point where the paint is coming off with it
