What Protective Measures Are Needed for Interior GRC Decorative Panels? Spatial Aesthetics and Qinglong Group's Interior Application System

While pursuing artistic effects, the application of interior GRC decorative panels requires strengthened protective measures in four key areas: "fire safety, environmental health, moisture and mold resistance, and impact resistance and maintenance." Based on extensive interior project experience with high-end hotels, commercial complexes, and cultural venues, Qinglong Group has established specialized standards: Class A non-combustible GRC materials must be used (with test reports provided); raw materials and finished products must meet green building material standards (e.g., formaldehyde-free, low VOC); hydrophobic and anti-mold treatment is required in damp spaces (such as bathrooms and swimming pools); and localized strength reinforcement or anti-collision strips are needed in impact-prone areas (such as external corridor corners). In a project featuring a 15-meter-high GRC artistic feature wall in the lobby of a five-star hotel in Shenzhen, we passed fire safety and environmental inspections in one go through material optimization and structural design, with no deformation or mold growth after five years of use. Interior applications demand that material performance be examined against higher standards.

Fire Safety and Environmental Protection Are the Bottom Line for Interior Applications

Interior GRC must be Class A non-combustible material, and all components (including adhesives and sealants) must meet the corresponding fire-resistance ratings. Qinglong interior GRC uses inorganic raw materials, eliminating fire risks at the source. Meanwhile, cement free of radioactivity and ammonia emissions is strictly selected, along with eco-friendly water-based release agents, ensuring that indoor air quality meets standards after completion.

Moisture-Proof and Anti-Mold Treatment for Complex Interior Environments

For damp environments such as kitchens, bathrooms, and basements, waterproof mortar should be applied to the back of GRC panels or a moisture barrier should be installed. Panel surfaces can undergo hydrophobic treatment to reduce water absorption and eliminate conditions for mold growth. At the indoor venues of Zhuhai Chimelong Ocean Kingdom, we added anti-mold and antibacterial coatings to GRC components with remarkable results.

Impact-Resistant and Easy-Maintenance Design Enhances User Experience

For GRC walls or columns in high-traffic areas, impact resistance can be improved below a height of 1.2m by increasing fiber content or incorporating flexible composite materials. External corners can be fitted with embedded metal or rubber corner guards. Surfaces are recommended to use scrub-resistant, anti-graffiti protective coatings for easier future maintenance.

Expanding Acoustic and Optical Functions

By designing surface textures and pores, interior GRC can also provide sound absorption, optimizing the indoor acoustic environment. Through pre-embedded light troughs combined with lighting design, unique artistic effects of light and shadow can be created. Qinglong Group provides full technical support from acoustic simulation to lighting testing.

Interior GRC is no longer a simple decorative material but a key element in creating healthy, safe, comfortable, and artistically rich spaces. Through systematic solutions, Qinglong Group achieves the perfect unity of art and function in interior spaces.
