Plain Wall Corners
Polure plain wall corners feature clean minimalist geometric corner profiles designed to seamlessly connect smooth wall mouldings and wainscoting frames. Molded from high-density rigid polyurethane (150-220 kg/m³), these unornamented corner elements offer wood-equivalent mechanical toughness while keeping structural weight low. 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 piece is supplied factory pre-coated in white acrylic primer. Installation requires clean surfaces, applying a continuous bead of polyurethane assembly adhesive on wall contact backs, 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.
