What Protective Measures Should Be Taken for Indoor GRC Decorative Panels? Qinglong Group's Environmental Adaptability Design and Maintenance System

The protection of interior GRC decorative panels requires focus on controlling three major risks: "humidity variation, mechanical impact, and cleaning damage", addressed systematically through "material optimization, structural design, and usage guidance". Drawing on projects such as the interior GRC ceilings at Huawei's Songshan Lake Headquarters and the GRG walls at Zhuhai Chimelong, Qinglong Group has summarized key protective measures: maintain ambient humidity at 40-70% to prevent drying shrinkage cracks; use reinforced GRC in impact-prone areas (impact resistance ≥10J); and select scrub-resistant coatings for surface treatment (abrasion resistance ≥1000 cycles). Our interior GRC panels have passed accelerated aging tests with a strength retention rate of ≥90% after 20 years of use, and maintenance costs are only 1/3 of those for exterior panels, making them especially suitable for high-end commercial spaces, cultural venues, and other locations with high demands for aesthetics and durability.

Humidity Control is the Foundation of Protection

The moisture content of GRC panels should be kept stable between 6-8%, with expansion joints reserved during installation (width ≥ 1/500 of the panel length). Qinglong Group provides humidity-regulating GRC for places with constant temperature and humidity, featuring built-in phase-change materials to buffer humidity fluctuations. In a data center project in Shenzhen, environmental monitoring resulted in zero panel cracking.

Mechanical Protection Extends Service Life

In high-traffic areas, panel thickness is increased to 20-25mm, with edges finished with rounded corners (R≥5mm). Qinglong Group has developed high-toughness GRC blended with PVA fibers, increasing fracture energy by 50%. Regularly inspect connection points to prevent loosening.

Cleaning and Maintenance Regimen

Establish cleaning guidelines and prohibit strong acid and alkaline cleaners; inspect surface condition every six months. Qinglong Group provides lifetime maintenance consulting to keep interior GRC looking new for the long term. Scientific protection maximizes the value of the material.
