How to Maintain GRC? Qinglong's Scientific GRC Maintenance Guide

As a high-performance building material, GRC products' maintenance directly affects their service life and aesthetic appearance. Based on 28 years of engineering practice, Qinglong GRC has developed a scientific maintenance system. Through regular inspection, professional cleaning, timely repair, and preventive protection, GRC products can be kept in good condition over the long term.

In the Shenzhen Yirui Biotechnology Building project, the maintenance program implemented by Qinglong achieved remarkable results: two comprehensive inspections per year, with drones assisting surveys of high-altitude areas; professional cleaning once per quarter using neutral cleaning agents and soft tools; and a digital maintenance archive recording every maintenance activity. Over 5 years of operation, the GRC curtain wall system has remained as good as new with no decline in strength performance, and maintenance costs were 30% lower than expected. In particular, to address the rainy southern climate, anti-mold treatment and water seepage detection were added, effectively preventing common problems.

Key Points for Regular Inspection and Maintenance

A comprehensive inspection is recommended every six months, focusing on joint sealing condition, surface coating integrity, and fastener security. Use the tapping method to check for hollowing, and immediately mark any issues found. Establish an inspection record sheet to track problem resolution progress.

Standard Procedure for Professional Cleaning

Cleaning frequency is determined by environmental conditions, generally once per quarter. Use a specialized cleaning agent with a neutral pH, together with a soft brush or sponge. Control the high-pressure water washer at 50-80Bar, with the nozzle at least 30cm from the panel surface. After cleaning, check that the drainage system is unobstructed.

Preventive Maintenance Measures

In heavily polluted areas, consider using anti-stain coatings. Coastal areas require enhanced anti-salt spray treatment. Regularly check the integrity of the waterproof layer and reapply protective agent promptly. Establish a preventive maintenance plan to eliminate problems at an early stage.

Requirements for a Professional Maintenance Team

Maintenance personnel must receive professional training and be familiar with GRC characteristics. High-altitude workers must be certified and equipped with safety protection gear. Establish an emergency maintenance mechanism with response to sudden problems within 24 hours.

Scientific maintenance can significantly extend the service life of GRC. It is recommended to develop a detailed maintenance plan and implement it strictly to maximize investment value.
