Curved Corner Joint Element
Curved corner joint elements engineered from high-density rigid polyurethane (150-220 kg/m³) provide seamless 90° transitions for rounded wall panel frames and curved ceiling moldings. Offering wood-equivalent mechanical strength and high impact resistance, these corner pieces ensure sharp architectural continuity without joint cracking. Their closed-cell structural formulation guarantees water absorption below 1%, making them suitable for humid microclimates like bathrooms or kitchens (-100 °C / +80 °C). Factory pre-primed with a smooth white acrylic technical primer, Polure curved corner joint elements allow easy finishing with water-based, synthetic, or acrylic paints. Installation requires clean mating surfaces, continuous PU assembly adhesive, and mechanical screw fixing (silicone is strictly forbidden). Lightly sand with 180-220 grit paper prior to painting for optimal paint adhesion.
Frequently Asked Questions
What is a curved corner joint element used for?
It connects linear wall moulding runs around curved corners, creating elegant rounded panel frames without miter gaps.
What material are Polure curved corner joint elements made of?
High-density rigid polyurethane (150-220 kg/m³), providing wood-like impact resistance and 100% moisture protection.
What adhesive should be used for installing curved corner joints?
Use a continuous bead of PU assembly adhesive along with countersunk screws. Silicone is strictly forbidden.
