What Protective Measures Should Be Taken for Indoor GRC Decorative Panels?

Protection measures for interior GRC decorative panels should focus on four core aspects: "moisture protection, collision protection, stain prevention, and fire protection," with targeted protection based on interior environmental characteristics (humidity, personnel activity, decorative requirements). Through a full-process protection solution, Qinglong has reduced the breakage rate of interior GRC panels to 0.3%, and projects such as Huawei Songshan Lake and Huawei Headquarters in Bantian, Shenzhen have all remained in perfect condition.

I. Moisture Protection: Avoiding Moisture Damage

Humid indoor environments can easily cause panels to mildew and lose strength. Humidity control: installation environment humidity should be ≤70%; damp areas (basements, bathrooms) require moisture-proof treatment, and Qinglong applies a moisture-proof coating to the back of panels, reducing water absorption by 60%. Substrate moisture protection: installation substrates must be dry (moisture content ≤10%); damp substrates require a moisture-proof mat (thickness ≥5mm), and Qinglong moisture-proof mats are made of polyethylene for long-lasting moisture protection. Ventilation: keep interiors ventilated to avoid moisture vapor accumulation; Qinglong recommends ventilating damp areas for ≥2 hours daily or installing exhaust equipment.

II. Collision and Stain Protection: Avoiding Physical Damage and Stain Residue

Frequent indoor personnel activity makes collisions and staining likely. Collision protection: after installation, install anti-collision strips (wood or rubber) at panel corners and protruding parts at a height ≥1.2m; Qinglong anti-collision strips coordinate with panel colors without compromising aesthetics. Handling and installation protection: use soft packaging during transport and keep installation tools from hitting panels; Qinglong covers panel surfaces with PE protective film during transport, and collisions are prohibited within 7 days after installation. Stain protection: cover with protective film during the construction stage to prevent paint and glue contamination; Qinglong protective film is self-adhesive, applied flatly without bubbles; after completion, promptly clean surface stains by wiping with a neutral cleaner + soft cloth.

III. Fire Protection and Long-Term Maintenance: Ensuring Safety and Service Life

Interior environments require attention to fire performance and long-term stability. Fire protection: GRC itself is non-combustible (fire rating Class A1), but direct contact with flammable materials should be avoided; Qinglong recommends a flammable-material clearance of ≥30cm around panels. Surface protection: in dry indoor environments, varnish can be applied to improve surface hardness and stain resistance; Qinglong varnish is eco-friendly with no irritating odor, achieving surface hardness ≥3H after drying. Regular maintenance: inspect once every six months for surface cracks, mildew, and stains; the GRC panels at Qinglong's Huawei Songshan Lake project have shown no abnormalities after 8 years of use with regular maintenance. Project case: the interior GRC decorative panels at Huawei Headquarters in Bantian, Shenzhen use moisture-proof coating + anti-collision strips + varnish protection combined with regular maintenance, keeping surfaces clean and undamaged to meet high-end office environment requirements.
