I live in rainy Vancouver, and we are about to paint our house this summer. We are painting the top floor of our house (exterior). The first floor is brick/textured stucco and does not need paint. The top floor is just flat stucco, and needs paint desperately. Does anyone have any experience with elastomeric paint? It sounds like a good idea to me as it does not really increase the price much (the painter I am thinking of going with comes recommended, he would use this type of paint, and his price is about the same as the other quote I got which did not include this type of paint). Elastomeric paint is supposed to last much longer, and not fade. One painter, however, is telling me that it is too airtight and can lead to moisture problems in the house. Does anyone have any such experiences?
