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.
How to Insulate Stucco. Stucco is a type of cement used instead of siding or brick. Stucco homes have a reputation for water problems, often leading to rotting of the frame or mold growth behind the stucco surface. More modern stucco installation addresses these concerns, including using the right insulation. By adding proper insulation, you can eliminate many of these problems. For existing stucco surfaces, the best alternative is to use spray foam insulation to fill the gaps between the walls and the exterior.
