Sun can cause your fiberglass pool to fade or crack. UV rays make the problem worse as they break down the surface over time. This post will show simple steps and tips for better fiberglass maintenance, sun protection, and longer-lasting pools.

Key Takeaways

  • Sunlight can fade and weaken fiberglass pools by breaking down their gel coat.
  • Use a pool cover to block harmful rays.
  • Coatings like ecoFINISH give strong UV protection, so colors last longer and surfaces stay smooth.

Understanding Sun Damage to Fiberglass Pools

Strong sun can break down the gel coat on fiberglass pools. Harmful UV rays fade colors and weaken the surface, causing cracks or chalky spots. Over time, this damage leads to rough pool walls that hurt your skin or snag swimsuits.

Ultraviolet light strips away protection from surface coatings. The pool may lose shine and look dull or patchy in just a few seasons without UV protection. Regular fiberglass maintenance stops these problems early, protects your investment, and keeps water safe for swimmers.

Preventive Measures for Sun Protection

Sun damage can hurt fiberglass pools, making them fade and weaken. Protecting your pool from the sun keeps it looking good and lasting longer. Here’s how:

  1. Use a pool cover. It blocks sunlight, keeping the water cool and protecting the surface.
  2. Install shade structures. These reduce direct sunlight on your pool, lowering temperature and sun exposure.
  3. Regular maintenance checks for fading or damage early, keeping small issues from getting big.
  4. Keep the chemical balance right. Proper pH levels protect the coating from breaking down in the sun.

By following these steps, you can enjoy a durable, beautiful fiberglass pool despite the sun’s harsh effects.
