How to Maintain GRC? Full Life-Cycle Maintenance Guide and Qinglong Professional Maintenance Solutions

Although GRC materials offer excellent durability and stability, long-term exposure to the natural environment still requires scientific maintenance to extend service life and keep the appearance intact. A sound maintenance plan can effectively prevent cracking, aging, contamination, and other problems. Drawing on 28 years of industry experience, this guide outlines the key points and practical methods for GRC maintenance throughout its full life cycle.

1. Routine Regular Inspections: Detect and Address Potential Issues Early

The core of routine maintenance is regular inspection. It is recommended to conduct an appearance check once a month and a comprehensive inspection once a quarter. Inspections should focus on the connection points, edges and corners, and surface coatings of GRC components, checking for looseness, cracks, peeling, color difference, and other problems. In the Pingshan High-Tech Zone Comprehensive Service Center project in Shenzhen, Qinglong established a professional inspection mechanism, using 3D laser scanning to compare component deformation data and ensure timely identification of potential hazards. For high-level GRC curtain walls, professional equipment must be used for elevated inspections to avoid blind spots missed during manual checks. Qinglong is equipped with a full set of high-level inspection equipment and can provide third-party professional testing services.

2. Targeted Cleaning and Care: Maintaining Appearance and Performance

Develop a targeted cleaning plan based on the service environment of the GRC components. Outdoor components should be regularly cleaned of surface dust, oil stains, bird droppings, and other contaminants—cleaning once every six months is recommended, using neutral detergents with soft tools to avoid scratching the surface. In coastal areas, increase the cleaning frequency and focus on removing salt spray residue to prevent corrosion. For coastal projects such as Poly Peninsula No. 1 in Hainan, Qinglong developed a dedicated anti-salt-spray cleaning and care agent that effectively enhances the corrosion resistance of components. Cleaning of indoor GRC components should focus mainly on dust removal; avoid cleaners containing corrosive ingredients, and promptly dry surface moisture after cleaning to prevent dampness and mildew.

3. Protection and Repair in Special Environments

In severely cold northern regions, anti-freeze protection is essential. Before winter arrives, check whether the sealant on components is intact and promptly replace aged sealing materials to prevent water infiltration that causes freeze-thaw damage. In high-temperature regions, monitor the aging of surface coatings and periodically reapply protective coatings; Qinglong's dedicated protective coating can enhance the components' UV resistance and extend their service life. If minor cracks, damaged edges and corners, or similar problems are found, repair them promptly using GRC-specific repair materials to ensure that the repaired performance matches that of the original components. Qinglong provides professional repair services and develops repair plans for different types of damage. For example, in the Third-Front construction project in Panzhihua, Sichuan, locally damaged GRC curtain wall panels were precisely repaired to restore their appearance and performance.

4. Long-Term Maintenance and Professional Support

Long-term maintenance of GRC components requires complete documentation, recording inspection results, maintenance measures, repair records, and more for easy traceability and management. A comprehensive assessment every 5-10 years is recommended, with renovation or replacement plans developed according to the degree of component aging. Qinglong provides 1-3 years of free maintenance service for cooperation projects; after the period expires, a long-term maintenance agreement can be signed, offering full-process support including regular inspections, professional maintenance, and technical consultation. Its professional maintenance team has extensive experience and can develop customized maintenance plans for different project types, ensuring the long-term stable use of GRC components.
