Addressing the Challenges of Acrylic Spa Maintenance

For spa service professionals and yacht owners alike, maintaining the aesthetic and functional integrity of an on-board spa can present unique challenges. Exposed to harsh marine environments, including relentless sunlight and potentially aggressive water treatment chemicals, acrylic spas can suffer from fading, crazing, and cracking, compromising their luxury appeal and usability. The quest for a viable solution to restore such weathered spas without resorting to costly replacements is a common one.

The Limitations of Conventional Coatings

The idea of applying a quick, cosmetic fix like Zolatone® or other pool paints might seem appealing for addressing surface wear. However, these products, designed for dry and semi-wet conditions, fall short in the constantly moist environment of a spa. Hybrid lacquer paints, including Zolatone®, are formulated for aesthetic applications in non-immersive settings and will rapidly deteriorate when applied to surfaces subjected to continuous water exposure.

Similarly, bathtub refinishing coatings, marine finishes, and even gel coats are ill-suited for spa resurfacing. These materials are not designed to withstand the dynamic conditions of a heated, chemically treated spa. They may offer a temporary improvement in appearance but fail to address the underlying issues of acrylic surface expansion, contraction, and moisture penetration, leading to peeling, bubbling, and further delamination.

Introducing the FiberGlass Reinforced Lining (FRL) System

Recognizing the need for a durable, long-lasting resurfacing solution for spas subjected to wet conditions, Multi-Tech Products developed the FiberGlass Reinforced Lining (FRL) system. This innovative approach involves a hand-laid application of special resin embedded with glass fiber reinforcement. This combination creates a robust barrier surface that adheres to the existing spa structure, minimizing expansion and contraction while offering a lifespan of 15 to 20 years.

The FRL system is uniquely designed to withstand normal spa conditions, including constant moisture and chemical exposure. It adds a structural finish approximately 1/8” thick, enhancing the spa’s strength and providing an attractive, textured white finish that conceals underlying damage and resists fading from sunlight.

Application and Benefits

One of the FRL system’s advantages is its straightforward application process, which does not necessitate the removal of spa jets or other fixtures. This makes it an ideal solution for spas with extensive crazing that does not yet result in severe peeling or delamination. The resulting layer not only revitalizes the spa’s appearance but also contributes additional structural integrity, offering an economical alternative to spa replacement in challenging settings like yachts.

Conclusion: A Sustainable Solution for Spa Restoration

The FRL system represents a leap forward in spa resurfacing technology, providing spa servicecompanies and yacht owners with a reliable method to extend the life of acrylic spas. Bychoosing the FRL system for spa restoration, professionals can deliver long-term value, ensuringthat these luxury amenities continue to offer relaxation and enjoyment for years to come.
