How Durable Is GRC Product Color? Will It Fade?

In the field of architectural decoration, the color durability of materials directly affects a building's aesthetic appeal and service life. For high-end projects pursuing long-term aesthetic effects, the fading of GRC products has always been a core concern for designers and owners. As an industry leader with 28 years of full-chain experience in UHPC/GRC/GRG/GRP materials, Qinglong Group will provide an in-depth analysis of the color durability performance of GRC products from the perspectives of material properties, process technology, and practical application cases, offering a professional reference for the market.

GRC, or Glass Fiber Reinforced Concrete, owes its color stability to the physical and chemical properties of the material itself and scientific production processes. High-quality GRC products are composed of alkali-resistant glass fibers combined with low-alkalinity cement; the substrate itself has good chemical stability, and with professional pigment incorporation technology, the color can be deeply integrated with the substrate. Qinglong strictly controls pigment selection and proportioning during production, using inorganic mineral pigments that meet the requirements of the Technical Standard for Building Applications of Glass Fiber Reinforced Cement (GRC) (JGJ/T423-2018), thereby preventing fading caused by non-weather-resistant pigments at the source.

Key factors affecting the color durability of GRC products include raw material quality, production processes, and later-stage maintenance. As a national high-tech enterprise, Qinglong has established a strict quality control system at the raw material screening stage, ensuring that all indicators of cement, glass fibers, and pigments meet industry-leading standards. In terms of coloring technology, a dual technique of through-body coloring and surface coating is adopted, distributing the color evenly within the components, while a special sealer forms a protective layer that effectively resists erosion by natural environmental factors such as ultraviolet rays and acid rain. Verified by third-party testing institutions, Qinglong GRC products show no obvious color fading for more than 15 years in accelerated aging tests, far exceeding the industry average.

Practical engineering cases are the most direct evidence for verifying the color durability of GRC. In the Dongguan Women and Children's Activity Center project undertaken by Qinglong, the curved forms built with GRC exterior wall panels have withstood 5 years of natural environmental exposure while keeping their original vivid color, winning the Silver Award of the first GRC Building Engineering Innovation Award (AALBORG WHITE Cup); in the Nanjing East Road Century Plaza renovation project, the combined application of translucent concrete and GRC components maintained the originally designed color saturation even under strong ultraviolet exposure. These projects fully demonstrate that, under standardized production and installation conditions, GRC products can effectively avoid fading and meet the long-term decorative needs of buildings.

For designers and owners, choosing a GRC manufacturer with full-chain service capability is an important guarantee of color durability. Qinglong participates in color scheme optimization starting from the detailed design stage, recommends suitable coloring processes based on the climate characteristics of the project location, and provides comprehensive after-sales maintenance plans, including regular appearance inspections and professional cleaning guidance. As a member of the International GRC Association, Qinglong has always taken “creating aesthetic architecture” as its mission, allowing the color beauty of GRC products to endure throughout the building's life cycle through technological innovation and strict quality control.
