        "text": "The lifespan of exterior wall weatherproofing depends on the materials used, the quality of installation, and environmental exposure. High-quality elastomeric coatings can last 10-20 years or more, while silicone-based sealants might offer similar longevity. Regular acrylic paints and sealants may require reapplication every 5-10 years. Coastal areas, like Pacifica or Half Moon Bay, experience harsher conditions that can reduce lifespan. Regular maintenance and periodic inspections can help identify areas needing attention, ensuring the longevity of your weatherproofing investment.",
