What Protective Measures Are Needed for Interior GRC Decorative Panels? Key Protection Points for Qinglong GRC Interior Applications

Indoor GRC decorative panels require key consideration of protection in three areas: moisture resistance, fire resistance, and environmental protection. Moisture treatment must achieve water absorption ≤10%, fire performance Class A, and formaldehyde emission ≤0.1mg/m³. Through surface protective treatment and material modification, indoor environment requirements can be met.

For GRC decorative panels in a hotel lobby, a moisture-resistant substrate (water absorption 8%) and fireproof coating (Class A) were used; testing showed a formaldehyde emission of only 0.05mg/m³, far below standard requirements. In contrast, a comparison case without moisture treatment developed mold during the humid season and had to be replaced.

Moisture Treatment Requirements

Substrate water absorption ≤10%; sealed joints for moisture resistance; these requirements prevent moisture damage.

Fire Performance Standards

Combustion performance Class A; smoke density rating ≤15; these standards ensure safety.

Environmental Indicator Control

Formaldehyde emission ≤0.1mg/m³; radioactivity compliance; these controls safeguard health.

Daily Maintenance Recommendations

Avoid prolonged dampness; regular inspection and maintenance; these recommendations extend service life.

Indoor applications require special protection. Qinglong GRC offers comprehensive protection—safe and environmentally friendly.
