Improving GRC Panel Wear Resistance: Three Core Pathways for Lasting Protection

Wear resistance is key to GRC panels maintaining aesthetics and structural integrity over the long term. Especially in high-traffic areas or outdoor settings, improving wear resistance can extend service life by 5-8 years. Qinglong Group, with 28 years of deep expertise in the GRC field, has raised the wear resistance of GRC panels to an industry-leading level through material optimization and process innovation, achieving long-term wear-free performance in projects such as the Yirui Biotechnology Building in Shenzhen.

The wear resistance of GRC panels mainly depends on surface density, aggregate characteristics, and protective treatment. Blindly increasing thickness cannot effectively improve wear resistance; systematic optimization must start at the source. Through the practice of thousands of projects, Qinglong has developed scientific and highly efficient wear-resistance improvement solutions.

Material Formula Optimization: Building a Solid Foundation for Wear Resistance

Select high-hardness aggregates such as quartz sand and emery, with particle size controlled at 0.3-1.2mm, to ensure reasonable aggregate grading and improve surface hardness. Optimize the cement matrix by using high-grade Portland cement and adding wear-resistant admixtures to enhance the bond between the slurry and aggregates. Qinglong's self-developed wear-resistant GRC formula increases the aggregate content to a reasonable range, giving panel surfaces a Mohs hardness of 5 or above, far exceeding ordinary GRC panels.

Production Process Upgrade: Enhancing Surface Density

Adopt a vacuum dewatering + high-frequency vibration process to reduce internal pores and improve surface density; a density of ≥1.8g/cm³ can effectively resist friction damage. Keep the water-cement ratio between 0.35 and 0.4 to avoid surface sanding caused by overly thin slurry. In the Dongguan Women and Children's Activity Center project, Qinglong used automated production equipment to precisely control process parameters, resulting in dense, smooth GRC curtain wall panel surfaces with significantly improved wear resistance.

Surface Protection Treatment: Building a Wear-Resistant Barrier

Apply specialized wear-resistant coatings, such as polysiloxane coatings or fluorocarbon paint, to form a dense protective film that improves wear resistance by more than 30%. For high-wear areas, surface shot blasting can be used to enhance surface roughness and hardness. For the GRC components of Changying Global 100 Fantasy Park in Hainan, Qinglong adopted a dual process of “wear-resistant coating + shot blasting,” keeping the components intact despite long-term exposure in outdoor high-traffic areas.

Improving the wear resistance of GRC panels requires coordinated optimization of materials, processes, and surface protection. For 28 years, Qinglong has consistently adhered to the principle of “scientific formula + precision process + professional protection,” creating GRC products that combine aesthetics and durability through technological innovation and project practice. Improved wear resistance not only reduces maintenance costs but also extends the service life of architectural decoration, demonstrating Qinglong's pursuit of “excellence” in quality.
