What peels paint on Miami block homes
Concrete block and stucco hold moisture. In Miami the summer rain soaks the wall, the sun bakes it dry again, and salt air drifting in from the coast settles on top of everything. Paint rolled over a wall that was never washed turns chalky first, then blisters, then lets go in sheets.
Hairline stucco cracks let water in behind the paint film, and the shaded sides of a house grow mildew that a fresh coat will not hide. Jalousie frames, terrazzo thresholds and trim edges usually show the first failures, because water sits there the longest.
