| Material | Saltwater Resistance | Maintenance Needs | Weight (Per Panel) | Aesthetic Appeal |
|---|---|---|---|---|
| White Travertino MCM | Excellent—salt cannot penetrate surface | Low—just wipe with water; no sealing needed | Light (10-15 lbs/sq ft) | Warm, natural travertine look with subtle veining |
| Natural Travertine | Poor—porous; absorbs salt, leading to pitting | High—seal every 6-12 months; prone to staining | Heavy (25-30 lbs/sq ft) | Timeless, but fades/discolors quickly in coastal areas |
| Fair-Faced Concrete | Moderate—resists but can develop salt stains | Moderate—may need pressure washing; cracks over time | Very Heavy (40-50 lbs/sq ft) | Industrial, modern—lacks warmth for many coastal styles |
| Rust Board | Poor—iron content rusts rapidly in salt air | High—requires regular rust treatment; lifespan short | Medium (18-22 lbs/sq ft) | Rustic, weathered look—until rust spreads unsightly |
