Polyurethane Crown Molding

Polure polyurethane crown molding delivers seamless architectural transitions between wall surfaces and ceilings with classic carved profiles. Manufactured from rigid high-density polyurethane (150-220 kg/m³), this crown molding offers wood-like mechanical toughness without cracking, warping, or sagging over time. Closed-cell polymer construction restricts water absorption below 1%, rendering the moldings resistant to rot and mold, and suitable for high-humidity bathrooms, kitchens, and exterior eaves (dimensional stability has been tested between -20 °C and +70 °C). Factory-coated with white acrylic primer, each section is ready for water-based or synthetic topcoats. Installation requires miter sawing 45° corner joints with precision, applying a continuous bead of polyurethane assembly adhesive across wall contact lines and joinery edges, and securing with countersunk screws. Fill screw heads and joints with facade acrylic putty, sand smooth using 180-220 grit paper, and finish with two coats of paint.
