GRC Maintenance Guide — Qinglong GRC Scientific Maintenance System

As a durable building material, GRC products require a systematic maintenance plan. Routine maintenance consists of three levels: daily cleaning (once per quarter), regular inspection (once every six months), and professional maintenance (once per year). Qinglong GRC recommends: clean surface dust with a neutral cleaner (pH=7±1), use specialized cleaning agents for stubborn stains, repair cracks ≤0.2mm wide with low-pressure grouting, and have major damage handled by professional teams. With scientific maintenance, the service life of GRC can exceed 50 years.

Maintenance standards: daily cleaning pressure ≤5MPa, water temperature ≤60°C; inspection uses a rebound hammer (strength), crack observation instrument (width), and moisture meter (moisture content); maintenance uses a specialized protective agent (weather resistance ≥10 years). The GRC components of a historic building, maintained under the Qinglong GRC maintenance system, remain in good condition after 30 years of use, with maintenance costs only 15% of the initial construction cost.

Daily Cleaning Specifications

Ordinary dust: soft brush or clean water rinse; oil stains: wipe with neutral cleaner; moss: remove with specialized moss remover; rain streaks: acidic cleaner (concentration ≤5%). Regular cleaning preserves appearance.

Regular Inspection Key Points

Crack inspection: record width, length, and direction; strength testing: year-on-year change in rebound values; connection inspection: looseness of anchors; waterproofing inspection: aging of joint seals. Preventive inspection identifies problems in time.

Professional Maintenance Measures

Surface protection: fluorocarbon coating (durability ≥15 years); crack repair: epoxy grouting (strength ≥ substrate); reinforcement: carbon fiber fabric (tensile strength ≥3000MPa); anti-corrosion treatment: rust inhibitor penetration (depth ≥10mm). Professional maintenance extends service life.

Maintenance Cycle Planning

Daily cleaning: once every 3-6 months; detailed inspection: once a year; professional maintenance: once every 5-8 years; major overhaul and renewal: once every 15-20 years. Scientific cycles control costs.

Scientific maintenance ensures long-term use. Qinglong GRC provides professional guidance to help you carry out maintenance properly.
