Ceiling Corner Molding
Polure ceiling corner molding profile creates a seamless, elegant transition between interior walls and ceilings while accentuating corner junctions with refined detail. Manufactured from high-density rigid polyurethane (150-220 kg/m³), this molding provides wood-like structural strength and exceptional resistance to physical knocks. Polyurethane will not warp, shrink, or crack over time, accommodating temperature variations from -100 °C / +80 °C. With closed-cell water absorption under 1%, it is fully safe against moisture and mold formation in kitchens and bathrooms. Each length is factory-coated with a smooth white acrylic primer layer. Installation involves dry substrate preparation, cutting 45° miter corners using a fine-tooth saw, applying continuous polyurethane assembly adhesive on wall contact edges and butt joints, and securing with screws. Screw recesses and joint gaps are puttied, lightly sanded (180-220 grit), and painted with interior topcoat paint.
Frequently Asked Questions
What density material is used for ceiling corner molding?
It is molded from high-density rigid polyurethane (150-220 kg/m³), ensuring strong structural durability.
Can ceiling corner molding be installed in high-humidity areas?
Yes, water absorption is under 1%, preventing mold, rot, and swelling in humid environments.
How is ceiling corner molding installed at joint intersections?
Cut 45° miter joints with a fine-tooth saw, apply PU assembly adhesive along all joining edges, and anchor with screws.
Does ceiling corner molding require priming before painting?
No, it arrives factory-primed with white acrylic primer ready for water-based or synthetic paint.
