What protective measures are needed for interior GRC decorative panels?

Although interior GRC decorative panels are not directly exposed to sun and rain, their protection requirements are equally significant, requiring systematic measures focused on fire safety, environmental health, stain and scrub resistance, moisture and mildew resistance, and installation stability. Through supplying interior GRC products to numerous star-rated hotels, high-end commercial complexes, and cultural venues, Qinglong Group has developed a comprehensive interior-specific protection system. For example, in the giant GRC art ceiling in the lobby of an ultra-five-star hotel in Shenzhen, we ensured its long-term safety and aesthetics in a densely occupied space through A1-grade fire protection treatment, food-grade surface protective coating, and precision installation.

Fire Safety Is the Lifeline of Interior Applications

The GRC substrate itself is a Class A non-combustible material, but when used indoors, the entire system (including possible backing materials, adhesives, etc.) must meet strict fire safety codes. Qinglong's interior GRC panels can be coated or impregnated with special fire-retardant coatings before leaving the factory, ensuring their combustion performance reaches Class A1 without producing toxic smoke in a fire. For areas with explicit fire resistance duration requirements (such as fire compartment partition walls), specialized fire-resistant structural design is required.

Environmental and Health Indicators Must Be Strictly Controlled

Indoor spaces are where people remain for long periods, making the environmental performance of materials crucial. Qinglong's interior GRC products strictly control the content of radioactive and harmful substances in raw materials, ensuring compliance with the national Standard for Indoor Environmental Pollution Control of Civil Building Engineering. Surface protective coatings are all water-based, low-VOCs (volatile organic compounds) eco-friendly products, and authoritative indoor air quality test reports can be provided upon completion.

Surface Stain Resistance, Scrub Resistance, and Abrasion Resistance

Interior walls and column surfaces are easily soiled by touch. Qinglong's interior GRC surfaces are finished with a dense, hard protective coating that offers excellent stain resistance (easy to clean), scrub resistance (over 10,000 cycles), and a certain degree of abrasion resistance. For hygiene-critical venues such as hotels and hospitals, the coating must also provide antibacterial and anti-mildew functions. We offer a range of textures from matte to high gloss to meet different design styles and functional requirements.

Moisture-Proof and Anti-Mildew Treatment Must Not Be Overlooked

In damp environments such as bathrooms, kitchens, and basements, GRC must undergo moisture-proof and anti-mildew treatment. In addition to the substrate's inherently low water absorption, the surface must be coated with a high-quality anti-mildew protective agent. During installation, air circulation behind the panels must be ensured to prevent long-term condensation. Areas in contact with the ground, such as GRC skirting, require additional moisture-proof sealing treatment.

Installation Stability and Seismic Requirements

The installation stability of interior GRC decorative components, especially large ceilings and elevated wall decorations, directly concerns personal safety. A reliable installation framework must be designed according to the building structure, and connection joints must have anti-loosening measures. In seismic design zones, the seismic loads of components must also be calculated. Qinglong provides a full range of technical services, from detailed design and embedded part positioning to installation guidance, ensuring that every interior GRC decoration is safe and reliable.

Therefore, the protection of interior GRC decorative panels is an all-around concept. Qinglong Group regards interior applications as a more stringent test of material safety, health, and durability, and through targeted technical solutions, ensures that while adding artistic value to interior spaces, there is absolutely no cause for concern.
