How Is the Surface Treatment Process of GRC Manufacturers Evaluated? Qinglong GRC Surface Quality Control System

GRC surface treatment process assessment must be evaluated from four dimensions: surface flatness (≤2mm/2m), color difference (ΔE≤3.0), texture restoration rate (≥95%), and durability (no fading for 5 years). Qinglong GRC uses advanced equipment such as the German BYK color difference meter and the British Taylor surface profilometer for quantitative testing to ensure stable surface quality.

In terms of process control, strict control is achieved through four procedures: base surface treatment (flatness ≤1mm/m), primer application (thickness 30±5μm), texture creation (texture clarity ≥95%), and topcoat protection (weather resistance ≥5 years). Each procedure has quantitative standards, with one inspection point set per 100㎡, and data is uploaded in real time to the quality management system to ensure uniform and consistent surface quality.

Flatness Control Standards

Overall flatness ≤2mm/2m; joint misalignment ≤1mm; these standards ensure aesthetics.

Color Difference Control Requirements

Color difference ΔE≤3.0 (measured by instrument); no visible color difference within the same batch; these requirements ensure uniformity.

Texture Evaluation Indicators

Texture clarity ≥95%; texture restoration rate ≥90%; these indicators evaluate the effect.

Durability Verification Methods

Weather resistance test of 1000 hours; stain resistance test reaching Grade 1; these verifications ensure long-term performance.

Surface quality requires precise control. Qinglong GRC's advanced processes ensure products are beautiful and durable.
