Polyurethane Molding Corner
Polure polyurethane molding corners ensure seamless 90-degree transitions, neat framing joints, and refined wall profile assemblies. Manufactured from high-density rigid polyurethane (150-220 kg/m³), these pre-molded corner elements avoid complicated 45-degree hand cuts while providing wood-like mechanical durability. Thanks to a closed-cell physical structure with water absorption under 1%, they resist humidity, warping, and mold, making them suitable for living spaces, kitchens, and humid bathrooms. Supplied with a factory-applied white acrylic primer, they easily receive final topcoats. Installation requires cleaning substrate surfaces, applying a continuous bead of polyurethane assembly adhesive on backing contact areas and joining edges, and fixing with countersunk screws. Screw holes and miter seams are filled with acrylic putty, sanded with 180-220 grit, and painted.
Frequently Asked Questions
What density material is used in the Polure polyurethane molding corner?
It is made of high-density rigid polyurethane (150-220 kg/m³), delivering high impact strength and B2 fire class safety.
Can a polyurethane molding corner be installed in humid bathrooms?
Yes, its closed-cell structure keeps water absorption under 1%, preventing swelling, rotting, or mold growth.
How is the polyurethane molding corner installed on wall trims?
Apply continuous polyurethane assembly adhesive to contact backs and joining edges, then secure mechanically with countersunk screws. Putty, sand, and paint.
What type of paint should be used on the polyurethane molding corner?
Water-based, synthetic, or cellulosic indoor paints can be applied after a light sanding with 180-220 grit sandpaper.
Is silicone adhesive permitted for mounting the polyurethane molding corner?
No, silicone adhesive is strictly forbidden because it lacks structural bonding strength. Only polyurethane assembly adhesive must be used.
