How Is the Texture of Biomimetic GRC Shapes Achieved?

How is the texture of bionic GRC shapes achieved? As an industry manufacturer with 28 years of full-chain GRC service experience, Qinglong GRC has summarized, through the implementation of thousands of public building and commercial real estate projects, a mature standardized path for achieving bionic textures—one that reproduces the delicate texture of natural materials while ensuring the durability and installation precision of GRC components.

The first step is the early-stage collection of texture prototypes and their parametric conversion, which is the core step that determines the fidelity of the bionic effect. For different bionic needs such as wood grain, stone grain, and bark textures, the professional team first uses 3D scanning technology to collect high-precision texture data from real natural substrates, then optimizes the texture based on the production characteristics of GRC materials—avoiding overly deep grooves that would make demolding difficult later, while adjusting the depth gradient of the texture to ensure visual layers close to the original material under different lighting angles. Currently, the texture reproduction accuracy of Qinglong GRC can be controlled at the 0.1mm level, fully meeting the aesthetic requirements of high-end projects.

The second step is the precise texture replication process in production. Currently, mainstream industry methods fall into two categories: one is custom mold precasting, where the corresponding texture is replicated on the mold surface and the texture is formed in a single step during the GRC slurry pouring stage; this method is suitable for mass-produced standardized bionic components, with controllable costs and high consistency. The other is later-stage manual fine carving—for custom bionic shapes with special double-curved surfaces, craftsmen with more than 10 years of experience hand-carve the texture during the initial setting stage of GRC, followed by curing, grinding, and sealing treatment, resulting in natural texture transitions with no visible joint marks.

The final step is weather-resistant reinforcement treatment of the texture surface. Many customers worry that bionic textures will fade or wear after long-term outdoor exposure. A proper treatment process involves spraying two layers of special protective coating after the texture is formed: the first layer is a penetrating sealer that fills the fine pores inside the texture to prevent moisture penetration, which would cause powdering of the base layer; the second layer is a weather-resistant matte topcoat that locks in the color saturation of the texture while avoiding glare and visual distortion under direct strong light. GRC bionic components treated with this process can maintain their texture outdoors for more than 15 years.

As an industry organization that participated in drafting the Technical Standard for Building Application of Glass Fibre Reinforced Cement (GRC), Qinglong GRC can now customize bionic textures of any natural material—from the faux stone facades of grand theaters to faux wood components in landscape gardens—balancing design effects with implementation feasibility, and providing full-process technical support for designers and owners.
