How to Choose the Adhesive for GRC Decorative Panels and Substrate? Qinglong GRC Bonding Technical Guide

The adhesive for bonding GRC decorative panels to the substrate should be selected according to the substrate type and service environment. Use epoxy resin adhesive for concrete substrates, with shear strength ≥2.0MPa; use flexible adhesive for lightweight walls, with deformation capacity ≥2.5%. Use weather-resistant adhesive outdoors, with durability ≥20 years.

An exterior wall project used epoxy resin adhesive; testing showed a shear strength of 2.5MPa, meeting seismic requirements. Qinglong GRC recommends dedicated adhesives to ensure secure bonding.
