Store employee asked what I was planning to paint over -- oil or latex. I replied that I didn't know because it was already on the house when we bought it, and (unlike with many of the interior paints) the previous owner hadn't left any of the exterior paint.
Store employee asked if the existing paint was cracking. I said that it was, and she said, "Then it must be oil based, because latex paints don't crack."
Is that true? So if I prep properly and paint with a 25-year warranty latex, the only reason to repaint within that time would be that we get tired of the color?
