Flat Column Topper
Polure flat column topper provides a sleek, low-profile modern capital for square and round decorative pillars. Engineered from high-density rigid polyurethane (150-220 kg/m³), this flat topper combines wood-like mechanical durability with a light structural footprint that avoids wall strain. Its closed-cell density limits water absorption to under 1%, making it completely resistant to rot, mold, swelling, and insect infestation in humid interiors or outdoor facades. Operational between -100 °C / +80 °C, it holds a B2 fire safety class for self-extinguishing safety. Supplied factory pre-primed with white acrylic technical primer, installation requires continuous PU assembly adhesive on mounting faces paired with mechanical countersunk screws. Fill screw holes with putty, sand smooth with 180-220 grit paper, and apply topcoat paint.
