Polyurethane Medallion
Polure polyurethane medallions add majestic architectural focus to ceiling centers and wall features. Molded from rigid high-density polyurethane (150-220 kg/m³), each medallion offers intricate classical detailing coupled with impact-resistant mechanical strength comparable to hardwood while staying lightweight. The closed-cell polymer matrix keeps water absorption below 1%, protecting the medallion against rot, warping, swelling, or mold in humid bathrooms, kitchens, and covered exterior porches. With thermal endurance ranging from -100 °C / +80 °C and a Class B2 fire-retardant rating, these medallions retain crisp crisp carved lines indefinitely. Pre-coated at the factory with a white acrylic primer, they accept any paint effortlessly. Installation involves cleaning the mounting surface, applying continuous beads of polyurethane assembly adhesive on rear rims, fixing with mechanical countersunk screws, patching screw holes with acrylic putty, sanding smooth with 180-220 grit paper, and painting with two coats.
Frequently Asked Questions
What material density is used for Polure polyurethane medallions?
Polure polyurethane medallions are produced from high-density rigid polyurethane (150-220 kg/m³), ensuring strong structural durability.
Can a polyurethane medallion be used in moist environments?
Yes, closed-cell polyurethane has water absorption under 1%, preventing rot, swelling, or mold in humid areas.
How is a polyurethane medallion properly installed?
Clean the surface, apply continuous polyurethane assembly adhesive, fix with mechanical screws, fill countersunk holes with acrylic putty, sand with 180-220 grit, and topcoat.
Why is silicone glue prohibited during polyurethane medallion mounting?
Silicone adhesive lacks structural bonding power. Mounting must be performed using dedicated polyurethane assembly adhesive along with mechanical screws.
What paint system is recommended for a polyurethane medallion?
Lightly sand the factory white acrylic primer with 180-220 grit paper, then apply two coats of water-based or synthetic paint.
