Lighthouse Lives On
Faced with constant pounding from 30-foot-high waves off the southeast mouth of Pleasant Bay, near Addison, Maine, the white brick exterior of the 132-year-old, 36-foot-tall Nash Island Light had seen its better days. During a recent renovation, the Maine Historic Preservation Commission searched for a coating that could withstand the harsh conditions (its previous coating had eroded in less than two years). The commission specified Silin Masonry Paint, a silica-based coating that bonds chemically with old or new masonry, blocking the penetration of water and minerals. Developed specifically for the maintenance and restoration of historic masonry structures, Silin also permits the release of water vapor that accumulates inside the masonry, reducing spalling and other structural failures.
