How to Maintain GRC? Qinglong Group's 28 Years of Maintenance Experience Explained

As a high-performance architectural decorative material, GRC should be maintained following the scientific principle of "prevention first, combining prevention with control." Qinglong Group, with 28 years of full-chain experience in GRC design, production, installation, and maintenance, has established a complete GRC maintenance system, dividing maintenance work into three levels: routine inspection, regular maintenance, and professional repair. In the Hainan International Convention and Exhibition Center project, by formulating an annual maintenance plan, we carried out systematic maintenance of 120,000 square meters of GRC roofing, maintaining a component integrity rate of over 99.5% over ten years, fully demonstrating the importance of scientific maintenance.

Establishing a Tiered Maintenance System Is Key

GRC maintenance should be managed in tiers according to component location, service environment, and importance. Qinglong Group divides GRC maintenance into three levels: Level 1 maintenance is routine inspection, conducted monthly, mainly checking superficial issues such as surface contamination and minor damage; Level 2 maintenance is periodic inspection, conducted every six months, with in-depth checks of key areas such as connection joints and sealant condition; Level 3 maintenance is professional testing, providing a comprehensive evaluation of structural safety and durability. In the maintenance of the "Red Lantern" curtain wall of the Wuhan Han Show Theater, we used drones for high-altitude inspection, greatly improving inspection efficiency and safety.

Targeted Maintenance Strategies for Key Areas

GRC components in different locations require different maintenance strategies. For exterior wall panels on high-rise buildings, focus on checking the corrosion of embedded parts and connection joints; for ground-level landscape components, focus on impact resistance and surface wear resistance; for components in humid environments, pay special attention to the condition of waterproof seals. In Qinglong's maintenance practice at the Shenzhen Pingshan High-tech Zone Comprehensive Service Center, we developed differentiated maintenance plans for GRC panels with different orientations and positions, effectively extending the material's service life.

Selecting Professional Maintenance Tools and Materials

Proper maintenance requires professional tools and materials. Qinglong Group has developed a dedicated GRC maintenance kit, including neutral cleaners, penetrating protective agents, and special repair mortars. For surface protection, we recommend silicone-based water repellents, which effectively prevent moisture intrusion while maintaining GRC's breathability. In the Nanning Wuxiang China Resources MixC One project, regular application of protective agents kept the GRC curtain wall looking as good as new after five years of use.

Establishing a Complete Maintenance Archive System

Scientific maintenance requires a complete record system. Qinglong establishes independent maintenance archives for each GRC project, recording in detail the time, content, problems found, and corrective measures for each maintenance. Such archives not only help track component conditions but also provide data support for future maintenance. In the Dongguan Women and Children's Activity Center project, complete maintenance archives helped us accurately predict component maintenance cycles, greatly improving maintenance efficiency.

GRC maintenance is a systematic project that requires professional knowledge and extensive experience. With 28 years of technical accumulation, Qinglong Group can provide customers with comprehensive GRC maintenance solutions, ensuring buildings remain in optimal condition over the long term.
