How GRC Manufacturers Assess Key Indicators in Surface Treatment Processes: Implementation Methods Explained

GRC Manufacturer Surface Treatment Processes: A Complete Guide to Key Assessment Indicators and Practical Implementation

Surface treatment is the "aesthetic coat" of GRC products and, more importantly, the core process that determines their long-term durability and use value. The technical level of a professional GRC manufacturer is often revealed in the details of this very process.

As a Qinglong GRC manufacturer with 28 years of industry experience, we deeply understand the critical role surface treatment processes play in project outcomes—from the exterior wall textures of high-end commercial complexes to the decorative finishes of municipal cultural venues, every detail tests a manufacturer's process control capabilities. For GRC surface treatment processes, the industry has developed a systematic assessment logic, the core of which can be summarized into three key indicators.

### GRC Manufacturer Surface Treatment Processes: Breaking Down the Three Core Assessment Indicators

First is the appearance and texture indicator, the most intuitive judgment criterion for designers and owners, covering three dimensions: surface flatness, color difference control, and texture fidelity. A quality GRC manufacturer must ensure component surface flatness error ≤2mm/m², color difference controlled within NBS1.5, and precise reproduction of the stone, metal, or special texture effects in design drawings—this is also the key to Qinglong GRC's recognition in numerous landmark projects. Next is the performance durability indicator, focusing on weather resistance, impermeability, and wear resistance. GRC products meeting the requirements of the "Technical Standard for Glass Fiber Reinforced Cement (GRC) Building Applications" (JGJ/T423-2018) must pass a 1000-hour artificial accelerated aging test with no obvious fading or cracking, and achieve an impermeability grade ≥P6. Finally is the environmental compliance indicator. Under the current green building trend, VOC emissions and heavy metal content in GRC surface treatment must comply with national environmental standards—this is also an aspect that Qinglong, as a national-level high-tech enterprise, has always strictly controlled.

### Qinglong GRC Manufacturer: The Standardized Implementation Path for Surface Treatment Processes

Implementing assessment indicators depends on standardized implementation methods. Starting from the full chain, Qinglong GRC manufacturer has built a three-level implementation system of "design first - process control - finished product inspection." In the design phase, we synchronize with designers on surface texture requirements through BIM parametric technology, simulating process feasibility in advance; during production, we adopt a "three-inspection system" to control every procedure—incoming raw material inspection, patrol inspection of the spraying process, and final pre-delivery inspection of finished products—to ensure consistency in surface treatment; for different project requirements, we can also customize and adapt various processes such as stone-effect sandblasting, fluorocarbon spraying, and fair-faced textures, meeting diverse designs ranging from classical European lines to modern minimalist facades.

For GRC manufacturers, surface treatment processes are not merely a technical issue but also a matter of deeply understanding and responding to customer needs. With 28 years of full-chain service experience, Qinglong manages the entire process from detailed design to after-sales maintenance, ensuring that every surface treatment process meets assessment standards, providing designers and owners with GRC solutions that combine aesthetic appeal with long-term durability, and helping projects achieve quality implementation.
