Introduction

Steve, a professional spa surface repair contractor, faces a challenging situation with recurring defects after repairing blisters on acrylic spas. This issue not only impacts the reliability of his work but also affects customer satisfaction. Understanding and addressing the root causes of these failures is crucial for ensuring durable repairs and maintaining a reputation for quality service.

Identifying the Problem

The appearance of new problems following initial repair attempts can stem from several factors. Steve’s experience with call-back requests points to a need for a deeper dive into the repair process to identify missteps or overlooked details that could lead to subsequent failures.

Potential Causes of Failure

1. Excessive Catalyst in Acrylic Filler: Using too much catalyst can lead to excessive peroxide, which may migrate to the surface, causing the coating to separate from the substrate and turn yellow.
2. Migration of Original Blister Fluid: Incomplete removal or inadequate sealing of the fluid causing the blisters can lead to the formation of new blisters. Ensuring a thorough drying process and creating a new barrier with binding resin and fiberglass mat is essential.
3. Poor Cure of Repair Coating: The repair coatings need proper curing conditions to harden adequately in wet areas. Premature exposure to water can halt the curing process, leading to blisters and peeling.
4. Improper Filler Use: Opting for non-acrylic fillers like polyester-based fillers can result in water absorption, delamination, and bubbling due to continuous exposure to hot water, chemicals, and sunlight.

Best Practices for Durable Repairs

To avoid the recurrence of blisters and ensure long-lasting repairs, Steve and other repair professionals should:

• Use the Right Materials: Always use Multi-Tech Products Acrylic Filler and the appropriate clear coat to protect the underlying base coat and filler.
• Ensure Proper Curing: Maintain a completely dry environment for a minimum of 5 days post-repair to allow coatings to cure and harden optimally.
• Educate Customers: Inform customers about the importance of the out-of-service period and follow up to ensure compliance with aftercare instructions.
• Avoid Shortcuts: Resist the temptation to save time or money by using alternative fillers. High-performance acrylic resins are necessary for spa repairs to withstand the spa environment.

The key to successful spa surface repairs lies in meticulous attention to detail, using the correct materials, and adhering to proven procedures.
