Salt air on the Isle of Capri, Isle of Palms and Paradise Island patios
Isle of Capri, Isle of Palms and Paradise Island sit on the bay side of Treasure Island with water on most sides of the lot, and the covered patio is where owners there want a second TV. Out there the enemy is salt, not rain. Zinc-plated lag bolts bloom rust within a season, and a powder-coated bracket starts to bubble wherever a wrench scratched it, so every exterior fastener we use on the isles is 316 stainless and every scratch gets touched up before we leave. On a ground-level block house the bracket goes into the CBS house wall with stainless masonry screws through the stucco, each hole primed with sealant before the screw goes in, and the masonry surcharge applies. On a home raised on pilings it lags into the framing behind the siding. The TV has to be outdoor-rated, or tucked so far under the roof that neither sun nor wind-blown spray can reach it. Power comes from a GFCI outlet under a weatherproof in-use cover, with a surge protector in line. A patio install on the isles takes 75-100 minutes.
