How to Protect Finished GRC Components After Installation?

Finished product protection for GRC components after installation must cover the full stages of 'transport protection, on-site protection, and later maintenance,' with the core goal of preventing impact, contamination, and weathering damage. Through customized protection plans, Qinglong keeps the damage rate of components after installation below 0.3%. Projects such as Qiangwei Garden in Zengcheng, Guangzhou, and Kaiyin New Town in Zhongshan have all been delivered flawlessly.

1. Protection During Transport and Installation: Avoiding Immediate Damage

Transport and installation are the key stages for protection. Transport protection: components are packaged with 'foam board + geotextile + steel frame,' with anti-collision strips (thickness ≥50mm) added at corners and edges; Qinglong's custom packaging keeps the transport damage rate ≤0.1%. Hoisting protection: flexible lifting devices (slings, spreader beams) are used, with soft pads placed where the lifting device contacts the component to avoid scratching the surface; Qinglong prohibits direct hoisting with steel wire ropes to prevent surface indentations. Installation protection: tools must not collide with components during installation, and safety nets are set up below work at heights to prevent injuries from falling objects; Qinglong installers are equipped with tool bags, and throwing tools around is prohibited.

2. On-Site Protection: Preventing Contamination and Accidental Damage

The on-site environment after installation can easily cause secondary damage. Contamination protection: component surfaces are covered with protective film (PE protective film, thickness ≥0.1mm) to avoid contamination from paint and cement slurry; Qinglong's protective film is self-adhesive, applied flat and bubble-free. Impact protection: protective barriers (wood or plastic) are set up at corners and protruding parts of components, with height ≥1.2m and warning signs posted; Qinglong keeps protective barriers at a distance of ≥10cm from components to avoid friction damage. Environmental protection: avoid prolonged exposure to sun and rain; when placed outdoors, the top should be covered with waterproof tarpaulin; Qinglong's outdoor protection period for components is ≥7 days, lasting until other exterior wall work is completed.

3. Later Maintenance: Extending Service Life

Long-term maintenance ensures stable component performance. Cleaning and care: promptly clean surface dust and stains after installation using neutral cleaners (pH 6-8); strong acids and alkalis are prohibited; Qinglong uses soft brushes and sponges as cleaning tools to avoid scratching surfaces. Regular inspection: inspect once a year to check the surface for cracking, peeling, or rust; Qinglong's coastal projects are inspected every 6 months to promptly address salt spray corrosion risks. Repair: minor cracks (width <0.3mm) should be repaired promptly with special repair agents; cracks with width ≥0.3mm require professional treatment; Qinglong's repair agents are compatible with GRC materials, ensuring a consistent appearance after repair. Project case: the GRC exterior wall components of the Shuiyunjian Villa in Changsha were given dual protection with protective film + barriers after installation, along with regular inspection and maintenance; after 5 years of use, the surface remains as clean as new, with no damage or contamination.
