Ceiling Corner Moulding
Polure ceiling corner moulding provides a smooth architectural transition between interior walls and ceilings, disguising structural joints with classic elegance. Molded from high-density rigid polyurethane (150-220 kg/m³), this coving moulding offers wood-equivalent mechanical toughness while keeping ceiling load minimal. Featuring a closed-cell physical matrix, its water absorption stays strictly below 1%, ensuring complete immunity to moisture, swelling, rot, and mold in humid rooms like bathrooms and kitchens. Fire-rated to class B2 and thermally stable between -100 °C / +80 °C, each length is supplied factory pre-coated in white acrylic primer. Installation requires clean surfaces, applying a continuous bead of polyurethane assembly adhesive on contact edges, and compulsory mechanical fixing with countersunk screws. Silicone adhesive is strictly forbidden. Joint lines and screw indentations are filled with acrylic filler, sanded smooth with 180-220 grit paper, and finished with interior water-based or synthetic topcoats.
Frequently Asked Questions
What material is Polure ceiling corner moulding made from?
It is manufactured from high-density rigid polyurethane (150-220 kg/m³), combining wood-like strength with lightweight ceiling mounting and B2 fire class.
Can ceiling corner moulding be installed in wet areas like bathrooms?
Yes. Water absorption is strictly under 1%, making it completely impervious to rot, swelling, or mold in humid rooms.
How is ceiling corner moulding installed?
Apply continuous PU assembly adhesive to contact edges and secure with countersunk screws. Silicone is forbidden. Fill screw holes with putty and sand smooth.
What paint finish is recommended for ceiling corner moulding?
Use interior water-based or synthetic paints for indoors, applied after light sanding with 180-220 grit paper.
