FEB 28, 2025

When choosing marine canvas, UV protection is one of the most important factors to consider. The sun’s rays can degrade fabric over time, causing fading, weakening fibers, and potentially leading to tears.

How UV Protection Works in Marine Fabrics: Marine canvas materials like Sunbrella and Harbortime are designed with UV inhibitors to block harmful rays. These inhibitors are embedded into the fabric during manufacturing, helping to prevent sun damage.

Why UV Protection Matters: Without UV protection, the fabric loses its strength and vibrancy. Over time, the material will become brittle and more prone to damage. UV-resistant fabrics extend the lifespan of your canvas, saving you from frequent replacements.

Maintenance Tips:

  • Wash Regularly: Dirt and saltwater can wear down UV inhibitors. Regular cleaning helps preserve them.
  • Store Properly: When not in use, store the canvas in a shaded, cool area.
  • Reapply UV Coating: Some fabrics may require a reapplication of UV-protective coatings every season.

By choosing high-quality UV-protected fabrics and following proper care routines, your boat’s canvas will stay strong and beautiful for years to come.
