Can the Manufacturer Provide a Usage and Maintenance Guide for GRC Products?

As an industry leader with 28 years of full-chain experience in the UHPC/GRC/GRG/GRP materials field, Qinglong Group understands that high-quality GRC products require not only exquisite design and manufacturing craftsmanship, but also scientific use and maintenance, which is the key to extending their service life and ensuring building safety and aesthetics. Many customers, after purchasing GRC components, often face the problem of 'emphasizing installation while neglecting maintenance,' resulting in degraded material performance and damaged decorative effects. Today, drawing on Qinglong's 28 years of engineering practice, we provide a systematic guide to the use and maintenance of GRC products to help your projects achieve long-term value.

Core Principles of GRC Product Maintenance: Prevention First, Scientific Care

GRC stands for glass fiber reinforced concrete, with cement, glass fibers, aggregates, and admixtures as its main components, offering the combined advantages of light weight, high strength, and flexible shaping. However, as a composite material, GRC maintenance must follow the principle of 'prevention first, categorized care.' During the compilation of the Technical Standard for Building Application of Glass Fiber Reinforced Cement (GRC) (JGJ/T423-2018), Qinglong conducted in-depth research on the aging mechanisms of GRC in different environments and summarized the 'three-stage maintenance method': initial care after installation, regular daily inspections, and special treatment for special environments. Take, for example, a commercial complex project undertaken by Qinglong: through strict implementation of this maintenance plan, its GRC exterior wall cladding panels showed no cracking, color difference, or other problems throughout a 10-year service period, far exceeding the industry average.

Daily Maintenance Essentials: Full-Dimensional Management from Cleaning to Structural Inspection

Daily maintenance is the foundation for GRC products to maintain their performance. First, cleaning should be done with neutral detergents, avoiding acidic or alkaline solutions that could corrode the surface; pay special attention to removing dust, bird droppings, plant sap, and other deposits from the surface. For complex GRC shapes such as decorative moldings and reliefs, a soft brush combined with low-pressure water flow can be used for washing, to prevent surface damage caused by high-pressure water jets. Second, structural inspections should focus on the stability of the anchoring system. Qinglong recommends visually inspecting the connection joints of GRC components every six months to check for loose bolts, corroded metal parts, and similar issues; where necessary, a professional institution can be commissioned to conduct pull-out force testing. In addition, for GRC components exposed to strong ultraviolet radiation and high humidity, a special protective coating can be applied every 2-3 years to improve their impermeability and weather resistance.

Handling Common Problems: Professionalism Determines Maintenance Outcomes

Even with proper daily maintenance, GRC products may still develop localized damage, cracks, and other problems, at which point professional solutions are essential. For small areas of surface damage, Qinglong's special repair mortar can be used to ensure color consistency with the original component. For structural cracks caused by foundation settlement, the crack width and development trend must first be analyzed: if the crack width is ≤0.2mm and stable, epoxy resin injection can be used; if the crack continues to expand, Qinglong's technical team should be contacted for structural reinforcement design. It is worth noting that non-professional repairs may cause secondary damage. For example, one project repaired GRC components with ordinary cement on its own, but inconsistent material shrinkage actually worsened the cracks; the problem was ultimately solved by the 'carbon fiber fabric reinforcement + special repair' solution provided by Qinglong.

Qinglong's Full-Cycle Maintenance Service: From 'Material Supplier' to 'Solution Partner'
