This large oval polyurethane ceiling medallion (P7149) serves as a dramatic architectural centerpoint, bringing baroque and neoclassical elegance to grand ceilings. Measuring an impressive 740x1100 mm with a 45 mm relief depth, its elongated oval geometry coordinates beautifully with rectangular dining rooms, reception halls, and hotel ballrooms, establishing an instant sense of structural balance.
Formulated from high-density rigid polyurethane (150-220 kg/m³), this architectural ornament offers the crisp, deep details of hand-carved timber without the associated weight or susceptibility to decay. The closed-cell structure provides moisture resistance, with low water absorption (below 1%), helping reduce the risk of warping, cracking, or swelling over time. It comes pre-primed from the factory, preparing the detailed relief surface for finish coatings. While this factory primer readies the surface, an optional secondary primer matching your chosen paint system is recommended for optimal paint adhesion, as paint manufacturer warranties often require specific system primers.
The P7149 features a highly detailed composition of acanthus scrolls, elegant rococo flourishes, and a central ribbed rosette ring. The deep 45 mm profile creates striking shadow lines, giving a three-dimensional depth that draws the eye upward. Its symmetrical, elongated form is ideal for framing grand chandeliers or decorating high-ceilinged reception rooms, providing a high-end finish that mimics traditional hand-carved plasterwork but with modern durability.
Designed for both high-end interior renovations and exterior architectural embellishments, this medallion has dimensional stability tested between -20 °C and +70 °C. For outdoor installations, such as portico ceilings or covered terraces, coating the medallion with a high-quality, UV-resistant exterior paint is mandatory to prevent natural yellowing over time. This makes it a highly versatile alternative to fragile gypsum or heavy wood alternatives.
Mounting the medallion is highly efficient compared to heavy plaster alternatives. The lightweight structure is secured using a polyurethane (PU) assembly adhesive combined with mandatory mechanical screw fixing. Once set, joints and screw heads are easily filled, sanded with 180-220 grit sandpaper, and finished with two coats of water-based or solvent-based paint, ensuring a seamless integration into your ceiling architecture.
- As a large-scale oval medallion, the P7149 is specifically proportioned for rectangular or oval architectural spaces
- Its primary application is as a decorative canopy for grand light fixtures, such as crystal chandeliers in luxury hotel lobbies, historic dining rooms, and spacious residential salons
- Its elongated 110 cm axis makes it perfect for anchoring long tables or centering in wide hallways and vestibules
- Beyond interior ceilings, it can be applied to exterior sheltered ceilings, such as grand entrance porticos, covered verandas, or classical gazebos, provided it is finished with a UV-stable exterior coating
- It can also be creatively mounted as a large decorative wall panel or overmantel ornament above grand fireplaces to introduce classical texture and relief to plain walls
- Ensure the mounting surface is clean, dry, and structurally sound
- Position the P7149 medallion and mark its placement
- Apply a generous bead of high-quality polyurethane (PU) assembly adhesive to the rear mounting rim of the medallion
- Press firmly against the ceiling
- Due to its 740x1100 mm dimensions, mechanical fixing with screws is mandatory to ensure safety while the adhesive cures
- Countersink the screws into the designated ornament crevices
- Once dry, fill the screw holes and any minor perimeter gaps with a suitable acrylic filler or lightweight compound
- Sand smooth using 180-220 grit sandpaper
- Apply an optional primer of your choice to ensure paint compatibility, then finish with two coats of premium water-based or synthetic paint
- For outdoor applications, a UV-resistant exterior paint is mandatory
- The P7149 requires minimal maintenance due to its closed-cell, non-porous structure
- For routine cleaning, dust the deep relief carvings with a soft static duster or vacuum with a brush attachment
- To remove smudges, wipe gently with a damp cloth and mild soapy water; avoid harsh abrasive pads, solvent-based cleaners, or strong acids
- Since the material has low water absorption (below 1%), it helps resist mold and mildew
- If the surface is damaged or scuffed over years of use, it can be easily repaired with standard painter's putty, sanded, and repainted to restore its original pristine appearance
Can this medallion be used outdoors, such as under a porch?
Yes, the P7149 is highly suitable for outdoor use on sheltered ceilings, porticos, and verandas. Assess water and moisture exposure using the product technical data, surface finish and installation details. However, because unpainted material can yellow under direct sunlight, applying a high-quality, UV-resistant exterior paint over the medallion is mandatory to protect it from UV degradation.
How do I hang a heavy chandelier with this medallion?
The medallion itself is decorative and must not bear the weight of any lighting fixture. A central hole should be drilled through the medallion to allow the chandelier's mounting chain or rod to attach directly to the structural ceiling joist or concrete slab above.
What makes this medallion better than traditional gypsum plaster?
Unlike fragile gypsum plaster, this high-density rigid medallion (150-220 kg/m³) is not prone to shattering, lightweight, and moisture-resistant. It resists cracking or crumbling over time, is significantly easier and safer to install on ceilings, and can be easily shipped with reduced risk of breakage.
Do I need to apply a primer before painting?
The medallion is delivered with a factory-applied primer that readies the surface for painting. However, paint manufacturers typically do not guarantee paint adhesion unless their proprietary system primer is used. Therefore, applying an additional primer compatible with your chosen paint is optional but recommended.
What adhesive should be used for installation?
You must use a dedicated polyurethane (PU) assembly adhesive to bond the medallion to the ceiling. Silicone adhesives are not suitable. Additionally, due to the medallion's large 740x1100 mm size, mechanical fixing with screws is mandatory for permanent safety.
