The document discusses the problems that occur with aging interior wall and ceiling finishes in food processing facilities, such as peeling, flaking, and corrosion. This deterioration increases cleaning costs and food safety risks over time. Common solutions such as painting, covering with panels, or replacement are temporary and restart the cycle of deterioration. The best solution is the FIXXUS engineered sanitation system, which has been used in 69 projects over 12 years to rehabilitate metal panels and concrete, seal joints and penetrations, providing a seamless hygienic surface and reducing long-term costs and risk of product contamination.
