RAL 7023

Concrete Grey

RAL 7023 Concrete Grey is a warm, natural grey that faithfully replicates the color of cured Portland cement concrete. This authentic, material-honest shade is specified for brutalist architecture restoration, industrial-chic interiors, and modern urban design where the raw aesthetic of exposed concrete is celebrated. Concrete Grey allows designers to achieve the concrete look on metal, wood, and other substrates without the maintenance challenges of actual exposed concrete surfaces.
