I have a 1920's stucco house in upstate New York. It is obviously not the right climate for these houses. These houses were built by a guy named Winchester and there are nearly 2 beautiful streets full of them. My problem is, it has been painted, but the paint blisters off after one year. What would be the best way to waterproof and paint this type of house? I'm wondering if it needs to be sand-blasted to it's original stucco and the simply waterproofed. It's been painted about 3 times in all its years. After all the scraping and caulking I've done, it would be great to get a reasonable solution. Thanks very much.
