What Houston Does To Paint
Chalking is old exterior paint breaking down into powder. Paint over it without washing and priming and your new coat is bonded to dust, and it will look perfect for about a year. Mildew grows on shaded elevations and under eaves and will grow straight back through new paint if it is killed and cleaned rather than just covered. And paint applied late in the day can catch dew before the film sets, which is why a crew racing to finish at six produces work that fails early.
