Smooth Column Capital
Polure smooth column capital delivers a minimalist, modern top element for unfluted or smooth architectural columns and pilasters. Molded from high-density rigid polyurethane (150-220 kg/m³), this clean-lined capital offers wood-like structural toughness without adding heavy load to walls or ceilings. Featuring a closed-cell matrix with water absorption under 1%, it remains resilient against humidity, mold, and rot in both interior and exterior environments. It retains shape across temperatures from -100 °C / +80 °C and carries a B2 fire safety classification. Arriving factory-primed in white acrylic paint, it readily accepts water-based or synthetic topcoats. Secure installation requires continuous polyurethane assembly adhesive on all contact edges and mechanical countersunk screws. Fill screw heads and joints with acrylic putty, sand with 180-220 grit, and finish with paint.
