Exterior Column Molding
Polure exterior column moldings provide clean architectural definition and weatherproof decorative framing for exterior columns and porch posts. Manufactured from high-density rigid polyurethane (150-220 kg/m³), these exterior moldings deliver wood-like durability and impact strength without rotting or denting under extreme weather. The closed-cell material features water absorption under 1%, guaranteeing zero swelling, mold, or moisture degradation in rain, snow, and humidity. Rated B2 for fire resistance and stable from -100 °C / +80 °C, each molding arrives pre-primed with white acrylic primer. Installation is completed by applying continuous polyurethane assembly adhesive to contact faces and joints, securing with mechanical screws, filling fastener heads with facade filler, sanding with 180-220 grit, and painting with UV-resistant exterior paint.
