Classic Crown Molding
Polure classic crown moldings deliver timeless architectural transition lines between ceilings and interior walls. Manufactured from high-density rigid polyurethane (150-220 kg/m³), these cornices feature sharp profile definition and wood-like durability without the heavy weight of traditional plaster. Engineered with a closed-cell polymer matrix and water absorption under 1%, they will never sag, warp, swell, or harbor mold in living rooms, bedrooms, or humid bathrooms. Thermally stable from -100 °C / +80 °C and rated B2 for fire safety, they arrive pre-treated with factory white acrylic technical primer. Installation is simple: cut 45° miters with a fine-tooth saw, apply continuous PU assembly adhesive along rear wall/ceiling contact surfaces and all joint edges, and secure with countersunk screws. Fill joints and screw heads with acrylic filler, sand smooth (180-220 grit), and paint with water-based topcoat paint.
