Chandelier Medallion
Polure chandelier medallions create a refined architectural centerpiece above hanging lights and ceiling fans. Engineered from high-density rigid polyurethane (150-220 kg/m³), these medallions offer sharp relief details and superior mechanical strength without adding significant load to ceiling joists. The closed-cell polymer matrix resists water absorption below 1%, making it imperious to warping, swelling, rot, or mold growth in bathrooms, dining areas, or outdoor verandas. Possessing high thermal tolerance from -100 °C / +80 °C and rated Class B2 fire-retardant, the medallion holds its crisp profile over long service life. Pre-primed with factory white acrylic primer, it accepts any topcoat smoothly. Mounting requires clean ceiling preparation, applying a unbroken bead of polyurethane assembly adhesive on rear surfaces, securing with mechanical screws, filling fastener countersinks with acrylic filler, sanding smooth with 180-220 grit paper, and painting with two coats.
Frequently Asked Questions
What density is used in Polure chandelier medallions?
Polure chandelier medallions are molded from high-density rigid polyurethane rated at 150-220 kg/m³ (production target ~160 kg/m³), providing wood-like durability.
Can a chandelier medallion be mounted in wet or humid rooms?
Yes, closed-cell polyurethane features water absorption under 1%, preventing rot, distortion, or mold in moisture-heavy environments.
What is the correct procedure for mounting a chandelier medallion?
Apply continuous polyurethane assembly adhesive, anchor with mechanical screws, fill countersunk holes with acrylic putty, sand with 180-220 grit, and topcoat.
Why is silicone adhesive prohibited when installing a chandelier medallion?
Silicone adhesive lacks structural bonding power and cannot reliably support polyurethane components. Polyurethane assembly adhesive and screws are required.
How should a polyurethane chandelier medallion be painted?
Lightly sand the factory white acrylic primer with 180-220 grit sandpaper, then apply two coats of water-based or synthetic ceiling paint.
