Introduction

Shane, working in the Warranty & Technical Department, encounters a perplexing issue: a clear topcoat applied during a spa repair process turns white within a month, despite careful adherence to product instructions and favorable repair conditions. This blog post delves into the causes of this discoloration and outlines steps for effective remediation.

Identifying the Cause

Discoloration of the clear topcoat is not only a cosmetic issue but also a sign of underlying problems in the curing process. Several factors can contribute to this outcome, all related to premature exposure to moisture. Understanding these factors is crucial for both prevention and correction.

Potential Causes of Topcoat Discoloration

1. Moisture Contact: If moisture, water, or dew settles on the fresh repair area soon after completion, it can interfere with the curing process, leading to discoloration.
2. Spa Lid Closure: Tightly closing the spa lid during the curing period can trap moisture from the spa’s jet system, keeping the repair area wet and preventing proper curing.
3. Early Spa Filling: Filling the spa with water before the topcoat has fully cured (a minimum of 72 hours at 70°F is recommended) can halt the curing process, resulting in a failure to achieve peak hardness and chemical resistance.
4. Cold Temperatures: Low temperatures significantly slow down the curing time of the coating. Any water contact during this extended curing period can cause the topcoat to turn white.

Steps for Repairing the Discolored Topcoat

To address and repair the whitened topcoat, it’s important to follow a comprehensive approach that ensures the topcoat can cure properly without interference from external factors.
