Stucco is a durable and beautiful building material, but homeowners should accept that it just isnât waterproof. If youâre concerned about damage to your home, look from these signs that your stucco is, indeed, due for a waterproofing job: Paint coating stucco is chipping, peeling, fainting, or cracking.
For stucco and other masonry surfaces a flat sheen is best, this allows the stucco to âbreath. When it rains the exterior of your house acts as a sponge absorbing small amounts of water. The flat paint allows the water to escape from stucco and brick without bubbling your paint.
