Decorative Crown Moulding
Polure decorative crown mouldings provide sophisticated ornamental framing along ceiling borders in residential and commercial interiors. Manufactured from high-density rigid polyurethane (150-220 kg/m³), these ornate cornices display intricately molded patterns while eliminating the brittleness and heavy weight of classical plasterwork. Engineered with a closed-cell polymer structure with water absorption under 1%, they will not warp, swell, or cultivate mold in humid interior environments or air-conditioned spaces. Thermally stable across temperatures from -100 °C / +80 °C and rated B2 for fire safety, they come pre-coated with factory white acrylic technical primer. Installation requires precise 45° miter cuts, continuous PU assembly adhesive along wall and ceiling contact lines, and direct screw mechanical anchor support. Fill joints and countersunk screw holes with acrylic putty, sand smooth (180-220 grit), and paint with topcoat paint.
Frequently Asked Questions
What material is used for Polure decorative crown moulding?
It is manufactured from high-density rigid polyurethane (150-220 kg/m³), offering wood-like durability, crisp detail, and B2 fire rating.
Are decorative crown mouldings affected by high indoor humidity?
No, with water absorption below 1%, polyurethane crown mouldings will not absorb water, warp, swell, or mold.
How should joints between decorative crown moulding lengths be glued?
Continuous PU assembly adhesive must be applied along all miter joint edges. Silicone is forbidden as it cannot hold polyurethane joints.
Can decorative crown moulding be painted with standard paints?
Yes, once sanded lightly (180-220 grit), it can be painted with water-based, acrylic, or synthetic interior topcoat paints.
