Pre-Primed Cornice

Polure pre-primed cornices offer professional contractors and homeowners immediate installation efficiency. Formed from high-density rigid polyurethane (150-220 kg/m³), each profile arrives factory-coated with a technical white acrylic primer that optimizes topcoat paint adhesion. The closed-cell polymer construction exhibits water absorption under 1%, ensuring no swelling, mold, or rot in humid rooms. Rated B2 for fire safety and operating stably from -100 °C / +80 °C, they provide long-lasting architectural elegance. Installation requires precision 45° miter cuts, continuous PU assembly adhesive on contact edges, and mechanical screw anchoring.
