The P721 is a premium decorative ceiling medallion designed to anchor interior ceiling layouts, especially around central lighting fixtures. With a substantial diameter of 745 mm and a depth of 48 mm, this architectural element bridges the gap between classic ornamentation and modern material science. It serves as a prominent visual focal point in spacious rooms, seamlessly integrating with chandeliers or hanging lights to elevate the overall architectural character of the space.
Manufactured from high-density rigid polyurethane (150-220 kg/m³), the P721 offers a robust structure comparable to natural wood but at a fraction of the weight. Its closed-cell composition ensures low water absorption, making it highly resistant to moisture, rot, and insect damage. The medallion is supplied with a factory-applied white primer that prepares the surface for painting. While this primer provides an excellent base, paint manufacturers often require their own specific primers for warranty purposes; therefore, applying an additional primer coat remains optional and at the discretion of the installer.
Visually, the P721 showcases an intricate arrangement of Baroque-inspired reliefs. A smooth, recessed central ring is enveloped by highly detailed floral bouquets positioned at four symmetrical axes, interspersed with delicate scrollwork, acanthus leaves, and textured detailing. These deep, 3D relief carvings create dramatic light and shadow play when illuminated from below. Unlike traditional plaster medallions that lose definition over time or crack, this molded polymer alternative retains its sharp, crisp lines indefinitely.
This decorative element is ideal for high-end residential interiors such as living rooms, dining halls, master bedrooms, and grand entrance foyers. It is equally suited for commercial hospitality settings, including luxury hotel lobbies, boutique restaurants, and historic renovation projects. While primarily designed for indoor ceilings, its weather-resistant properties allow for installation in covered outdoor areas like porches or veranda ceilings, provided it is finished with a UV-resistant topcoat.
Installation is significantly faster and safer than plaster or heavy timber alternatives. The lightweight unit is secured using a high-quality polyurethane (PU) mounting adhesive, supplemented by mechanical screws for absolute safety during the curing process. Once cured, screw heads and joints can be easily filled with standard acrylic filler, sanded with 180-220 grit paper, and painted with water-based or synthetic paints. This efficient process eliminates the messy, time-consuming curing times associated with plaster.
- The P721 ceiling medallion is versatile, designed primarily as an architectural accent for ceiling centers
- In residential projects, it is most commonly placed above dining tables, in the center of formal living rooms, or in master suites to frame chandeliers, pendant lights, or ceiling fans
- For larger, grand-scale ceilings, multiple medallions can be arranged symmetrically within ceiling coffers or panels to create a structured, neoclassical ceiling layout
- In commercial spaces such as boutique hotel suites, reception areas, and upscale retail stores, it adds historic depth while remaining lightweight and putting only a limited load on the structure
- Due to its moisture-resistant properties, it can also be safely installed in high-humidity areas such as luxury master bathrooms or covered outdoor balconies, adding a refined touch to areas where plaster or wood would degrade
- Begin by ensuring the ceiling surface is clean, dry, and free of dust or grease
- Mark the exact center of the installation area and pre-drill a center hole if a light fixture wire is present
- Apply a generous bead of polyurethane (PU) mounting adhesive to the flat back rim of the medallion
- Press the medallion firmly against the ceiling
- For secure, permanent placement, mechanical fastening with screws into the ceiling joists or plasterboard is mandatory
- Once the adhesive has cured, fill the screw holes and any peripheral gaps with an appropriate acrylic filler
- Sand these areas smooth using 180-220 grit sandpaper
- Finally, apply a premium topcoat of water-based or synthetic paint to match your ceiling design
- Note that while the factory primer is ready for paint, an optional extra primer coat can be applied based on your paint manufacturer's guidelines
- Maintaining the pristine appearance of the P721 medallion is simple due to its durable, non-porous polyurethane surface
- Regular dusting with a dry, soft microfiber cloth or a static duster is usually sufficient
- For deeper cleaning, the surface can be wiped down with a damp cloth and a mild soap solution
- Avoid using abrasive sponges, steel wool, or harsh chemical solvents, as these can damage the paint finish
- If installed in semi-outdoor environments or areas exposed to indirect sunlight, ensure a high-quality UV-resistant paint is used during initial installation to prevent any yellowing or discoloration over time
Can the P721 ceiling medallion be used in outdoor areas?
Yes, the P721 can be installed in covered outdoor areas such as porches, patios, and verandas. Assess water and moisture exposure using the product technical data, surface finish and installation details. However, to prevent yellowing or degradation from indirect sunlight, it must be finished with a high-quality UV-resistant exterior paint.
What adhesive should be used for installing this polyurethane medallion?
For a secure and lasting bond, you must use a high-quality polyurethane (PU) mounting adhesive. Standard silicones or hot glues should not be used as they do not provide the necessary structural bonding. Additionally, mechanical fastening with screws is mandatory to support the weight while the adhesive cures.
Does the P721 require an extra coat of primer before painting?
The medallion comes factory-primed with a high-quality white base, making it ready for direct painting with water-based or synthetic paints. However, because many paint manufacturers do not guarantee their coatings unless applied over their own brand-specific primers, applying an additional primer coat is optional but recommended depending on your paint choice.
How does polyurethane compare to traditional plaster ceiling roses?
Polyurethane is significantly lighter, making installation safer and easier without structural reinforcing. Assess water and moisture exposure using the product technical data, surface finish and installation details.
Can I install a heavy chandelier with this medallion?
Yes, but the medallion itself must not carry the weight of the light fixture. The chandelier's mounting bracket or chain must be anchored directly into the ceiling's structural joists or concrete slab through the center hole of the medallion. The medallion serves strictly as a decorative cover.
