Preventing Blistering and Bubbling in SPC Wall Panels

SPC wall panels are widely used in bathroom applications thanks to their excellent waterproof and moisture-resistant properties, offering both durability and aesthetic appeal. However, despite these advantages, issues such as blistering and bubbling may still occur if problems arise in materials, production processes, or installation and usage.

Common Causes of Blistering and Bubbling in SPC Wall Panels

1. Material Issues

The core of SPC wall panels is made by hot pressing PVC and calcium carbonate. If the formulation ratio is unbalanced—for example, when the calcium carbonate content is too high or recycled materials are used—the water absorption rate of the substrate increases. Excessive water absorption can easily lead to moisture-related blistering or bubbling.

2. Process Issues

During production, improper control of temperature, pressure, or pressing time can cause poor adhesion. In addition, if the production environment is not clean, dust or air bubbles may remain on the surface, creating gaps between the wear layer and the substrate. These voids often expand under heat or moisture, resulting in visible blistering and bubbling defects.

Some manufacturers even omit the use of a moisture barrier film to cut costs, which eliminates a critical layer of protection and increases the risk of surface problems.

3. Usage Issues

If the wear layer or the moisture barrier film is accidentally damaged during installation, the protective function of the panel will be compromised. Improper maintenance during daily use can also allow water to seep in, leading to surface bubbling or larger blisters that affect both performance and appearance.

How Trioflor Prevents Blistering and Bubbling

1. Material Assurance

Trioflor insists on using 100% virgin raw materials and never recycled content. We strictly follow standardized formulation ratios, and every product undergoes thorough quality testing before leaving the factory. Our panels are backed by CE certification and SGS test reports, ensuring consistent quality and minimizing risks of blistering or bubbling caused by poor material performance.

2. Strict Manufacturing Process

Trioflor strictly adheres to the ISO 9001 quality management system. The pressing process parameters—temperature, pressure, and time—are carefully monitored throughout production. By ensuring precision at every step, we eliminate air pockets and prevent weak adhesion, effectively reducing the possibility of bubbling and blistering over time.

3. Customer Support in Usage

Trioflor provides customers with complete market support tools, including installation manuals and instructional videos. Through training and guidance, we help minimize risks during transportation and installation. In addition, our continuous after-sales support ensures customers enjoy peace of mind, knowing that potential blistering or bubbling issues can be avoided through proper handling and maintenance.

Conclusion

SPC wall panels deliver outstanding waterproof and moisture-resistant performance, making them a reliable choice for bathroom wall applications. While blistering or bubbling may occur if materials, processes, or usage are mishandled, Trioflor effectively prevents these problems through premium raw materials, rigorous production standards, and comprehensive customer support—offering solutions that are truly Durable, Reliable, and Worry-Free.
