How to Maintain GRC? Qinglong's Scientific GRC Maintenance System Explained

Scientific maintenance of GRC products is key to ensuring their long-term performance and aesthetics. Based on 28 years of engineering experience, Qinglong GRC has developed a four-in-one maintenance system of "regular inspection, professional cleaning, timely repair, and preventive protection." Under normal conditions of use, high-quality GRC can achieve a service life of over 50 years with scientific maintenance.

In a commercial complex project in Shenzhen, Qinglong GRC established a comprehensive maintenance archive: a full inspection every six months, focusing on joints and surface color changes; professional cleaning every year using neutral cleaning agents; and protective coating renewal every five years. A follow-up visit after 8 years of use showed that the products remained as good as new, with maintenance costs accounting for only 0.5% of the construction cost. This scientific maintenance system ensures the long-term performance of GRC.

Regular Inspection System

A comprehensive inspection is recommended every 6 months: check whether joint sealants have aged or cracked; observe the surface for contamination or discoloration; check whether connectors are loose. Establish an inspection archive to record each inspection.

Professional Cleaning Standards

Professional cleaning is carried out once a year: use a pH-neutral specialty cleaning agent; keep the water temperature between 15-35℃; keep pressure washing equipment at ≤50Bar. Avoid using strong acid or alkali cleaners.

Timely Repair Measures

Address cracks immediately upon discovery: cracks ＜0.2mm are treated with surface sealing; 0.2-0.5mm with low-pressure grouting; cracks ＞0.5mm require professional repair. Repair materials must be compatible with the base material.

Protective Coating Renewal

Protective coating is renewed every 5 years: choose a breathable silicone coating; thoroughly clean the base surface before application; ensure the coating thickness is uniform and meets standards. This effectively extends the service life.

Scientific maintenance requires professional guidance. It is recommended to develop a detailed maintenance plan. Qinglong GRC provides customers with comprehensive maintenance guidance services.
