How to Maintain GRC? Full Life-Cycle Maintenance Guide and Key Points

The core of GRC maintenance lies in "regular inspection + scientific cleaning + timely repair". With proper standardized maintenance, high-quality GRC products can have a service life extended to 20-50 years. Backed by 28 years of maintenance experience, Qinglong has developed full-process maintenance solutions adapted to different scenarios.

I. Daily Basic Maintenance: Simple and Easy-to-Operate Daily Care

Daily maintenance focuses on preventing contamination and minor damage. Regular cleaning: Indoor GRC should be cleaned every 3-6 months and outdoor GRC every 1-3 months, wiped with clean water and a soft-bristle brush to prevent dust buildup from affecting the appearance; Damage prevention: Striking or scratching the GRC surface with sharp objects is prohibited, and heavy objects must not be stacked on outdoor components. Qinglong provides a "Daily Maintenance Manual" at delivery, clearly specifying prohibited behaviors; Environmental protection: In coastal areas, salt spray on the surface must be removed regularly; in northern winters, snow and icicles should be cleared promptly to avoid freeze-thaw damage. Qinglong provided a dedicated coastal maintenance solution for the Hainan Poly Peninsula No. 1 project.

II. Regular Professional Inspection: Identifying Potential Hazards in Advance

Professional inspection is key to extending service life. Inspection frequency: at least once a year during the warranty period and once every 2-3 years after the warranty period; major projects may entrust the manufacturer with special inspections. Inspection content: check the surface for cracks, fading, and weathering; check whether connectors are loose or rusted; and check whether the sealant has aged. Qinglong's inspection team is equipped with professional equipment capable of accurately detecting fine cracks (≤0.1mm). Problem recording: establish inspection files that record the location and severity of problems in detail to provide a basis for subsequent repairs. Qinglong sets up electronic inspection files for partner projects, supporting full life-cycle traceability.

III. Maintenance in Special Environments: Targeted Protection Solutions

Different environments require differentiated maintenance strategies. Coastal areas: High-salt-spray environments easily cause corrosion of metal connectors; apply anti-corrosion treatment to connectors every 1-2 years, and a hydrophobic agent may be coated on the GRC surface to enhance salt-corrosion resistance. Qinglong's Ouargla Hotel project in Algeria adopted a dedicated anti-corrosion coating with no rusting over 5 years. Cold regions: Winter freeze-thaw cycles easily cause cracks; clear surface water before it freezes, and cracks ≥0.3mm must be repaired promptly. A Qinglong municipal project in Northeast China avoided freeze-thaw damage through dedicated winter maintenance. Industrial environments: For dust and chemical corrosion, increase cleaning frequency and install protective covers where necessary. GRC railings at a chemical industrial park maintained by Qinglong with regular dust removal plus anti-corrosion coating showed no deterioration after 4 years of use.

IV. Core Maintenance Principles: Minimal Intervention, Precise Repair

GRC maintenance should avoid excessive operations and focus on key issues. Prevention first: identify hazards such as loose connectors and fine cracks early through regular inspections and address them promptly to keep problems from escalating. Scientific repair: minor cracks can be filled with a dedicated repair agent, while severe damage requires contacting the manufacturer to replace components; Qinglong provides original factory parts to ensure that repaired performance matches the original product. No blind handling: do not use strong acid or strong alkali cleaners without authorization and do not polish the surface arbitrarily, to avoid damaging the GRC structure and appearance. Qinglong once provided repair services for a project damaged by improper operation, achieving a restoration rate of over 95%.
