I'm in New Orleans, which at this point in the summer runs about 70% humidity and afternoon rain. I know that one is not generally supposed to paint without a 24 hour window.
We've been painting houses in this sort of weather using a Kelly Moore recycled paint. I've never had any problems with paint bubbling up.
However, two houses, in the same geographical area, have had problems with the paint bubbling 24-48 hours after having painted it. This only has happened with Behr paints. In both instances the environment was high humidity with possible rain (it did rain between 4 and 12 hours after application). The surface was scraped or pressure washed, depending on the lead content. In both cases we had several other houses running concurrently within a few blocks, so ostensibly, the same weather conditions.
One house was previously painted wood, the other was previously painted aluminum siding. On the wood house there were large (a few inches wide) bubbles, on the aluminum house there were small (several millimeters wide) bubbles. The surface was primed with Zinsser peel stop.
Has anyone ever run into these problems with Behr paints? And if so, are there solutions that anyone can give?
