Welcome to The Composite Company's guide to selecting the best decking materials for a coastal retreat.

Choosing the right decking materials is crucial to ensure your outdoor space can withstand these conditions while maintaining its beauty and functionality. In this blog post, we will explore the best decking materials that are specifically designed to withstand saltwater, UV rays, and other coastal challenges. Trust The Composite Company to provide you with high-quality decking solutions that combine durability, aesthetics, and longevity, ensuring a breathtaking coastal retreat.

Understanding Coastal Challenges

Living in a coastal area exposes your outdoor space to several challenges that can impact the longevity and performance of your decking. Here are the key challenges to consider:

  1. Saltwater Exposure: Saltwater can cause corrosion, rot, and decay in certain decking materials, compromising their structural integrity.

  2. High Humidity and Moisture: Coastal areas often experience high humidity levels, leading to increased moisture content in the air. Moisture can promote mold, mildew, and rot if the decking material is not moisture-resistant.

  3. Intense UV Radiation: Coastal regions also face intense sunlight and UV radiation, which can cause fading, discoloration, and deterioration of certain decking materials.

Best Decking Materials for Coastal Retreats

  1. Composite Decking: Composite decking is an excellent choice for coastal retreats due to its durability and resistance to saltwater, moisture, and UV rays. Composed of a blend of wood fibers and recycled plastic, composite decking offers the natural look of wood with enhanced durability and low maintenance. It does not warp, splinter, or rot, making it ideal for saltwater environments.

  2. PVC Decking: PVC (polyvinyl chloride) decking is another popular option for coastal areas. It is highly resistant to saltwater, moisture, and UV rays. PVC decking is lightweight, low-maintenance, and doesn't require sealing or staining. It offers excellent durability and is available in a variety of colors and finishes.

  3. Tropical Hardwood Decking: Tropical hardwood decking, such as Ipe, Cumaru, or Tigerwood, is naturally resistant to saltwater, insects, and rot. These dense and durable hardwoods have a rich, natural beauty that complements coastal aesthetics. However, they do require regular maintenance and periodic sealing to maintain their longevity and appearance.

  4. Aluminum Decking: Aluminum decking is gaining popularity for coastal applications due to its corrosion resistance and low maintenance requirements. It is impervious to saltwater, won't warp or splinter, and has excellent heat reflection properties, keeping the surface cooler under the hot sun.

Maintenance Tips for Coastal Decking

  1. Regular Cleaning: Regularly clean your coastal deck to remove salt residue, dirt, and debris. Rinse the deck surface with freshwater and use a mild detergent to remove any stubborn stains. This helps prevent salt buildup and maintains the appearance of your decking.

  2. Sealing and Finishing: Depending on the decking material you choose, consider applying a protective sealant or finish to enhance its resistance to saltwater, UV rays, and moisture. Follow the manufacturer's recommendations for sealing and finishing products and maintain a regular reapplication schedule.

  3. Decking Inspections: Perform regular inspections of your coastal deck to identify any signs of damage or wear. Look for loose boards, corroded fasteners, or any other issues that may compromise the deck's stability and safety. Address these issues promptly to prevent further damage.

  4. Proper Ventilation: Ensure proper ventilation underneath the deck to promote air circulation and minimize moisture buildup. This helps prevent mold and mildew growth, which can be common in humid coastal environments.
