The front of my house has a small decorative Mission tile decorative roof. Three years ago, the tile was painted over and the house was re-stuccoed. There was a bit of running from the paint in the first two years after the work was done but last winter it started really running.
I don't know the kind of paint that was applied though I could possibly find out from the builders who did the work. I have found that it eventually does come off the white, unpainted stucco with oxygen bleach and light scrubbing.
Eventually I'd like to replace the tile but can't do that immediately. Is there something I can do to prevent the streaking? For example, is there a type of sealer or coating I could apply to the painted tile?
