The P2842A decorative pediment is a classic architectural embellishment designed to create a magnificent focal point on building facades and interior transitions. Featuring grand dimensions and rich relief carvings, this product crowns doors and windows, adding depth and character to any structure.
Measuring 92.5 cm in width, 91 cm in height, and 20.5 cm in depth, this large-scale crown is manufactured from high-density rigid polyurethane (150-220 kg/m³). Include the product weight and fixing loads when assessing the substrate and supporting structure. The closed-cell structure keeps moisture and water absorption below 1%, preventing rotting, swelling, or cracking in rainy, snowy, and humid environments.
The visual design features symmetrical leaf motifs, elegant scroll (volute) forms, and a central circular shield detail. The fan-like acanthus leaves at the top beautifully blend the noble lines of classical Roman and Greek architecture with modern manufacturing quality. The factory-applied primer preserves the sharp details of the patterns while preparing a perfect surface for a smooth final coat of paint.
With its grand and tall structure, it is ideal for grand villa entrances, hotel lobbies, over-mantel fireplace decorations, and historical building restorations. Suitable for both interior and exterior use, this product serves as a primary visual element crowning window trims or grand interior doorways. For exterior applications, coating with UV-resistant paint is mandatory to protect it from the weathering effects of sunlight.
Unlike traditional plaster or heavy marble pediments, this lightweight decorative element carries no risk of breakage, allowing for fast and safe installation on-site. During installation, the surface must be cleaned, Polure Polfix adhesive applied to the back, and mechanical fastening secured with screws. Although the factory-applied primer makes the surface ready for painting, paint manufacturers may not guarantee applications done without their own primers; therefore, applying an additional primer coat is entirely at the customer's discretion. Polure does not accept liability for the performance of the paints used.
- The P2842A decorative crown model is specifically designed to be used as a pediment over wide doors and windows
- In exterior designs, it lends a monumental appearance to buildings when placed over villa entrance doors, at the top of window trims, or at floor molding intersections
- Indoors, it creates a luxurious detail in hotel reception areas, classically decorated restaurants, and over grand living room doorways
- It can also be functionally utilized atop decorative columns framing fireplaces or as a crown molding for library bookshelves
- For outdoor applications, painting with UV-resistant paint ensures a long-lasting exterior embellishment
- The installation surface must be completely free of dust, dirt, and moisture
- Apply Polure Polfix polyurethane adhesive to the back of the product and mount it to the wall
- Due to its large dimensions and weight distribution, mechanical fastening with screws is mandatory during installation
- Screw heads and joints should be filled with an exterior-grade filler, and once dry, sanded smooth with 180-220 grit sandpaper
- An additional primer coat can optionally be applied before painting, followed by at least two coats of paint to complete the installation
- The polyurethane crown can be easily cleaned with a damp cloth
- Avoid using abrasive chemicals or harsh acidic cleaners that could damage the surface during cleaning
- For exterior applications, periodic paint inspections are recommended depending on weather conditions
- Any minor damage from impacts can be easily repaired by applying filler, sanding, and spot-painting to restore its original appearance
What is the lifespan of the P2842A model on exterior facades?
Thanks to its rigid polyurethane structure, it does not rot, warp, or crack under outdoor conditions. When painted with UV-resistant exterior paint, it retains its shape for the lifespan of the building.
Which adhesive should be used for installation?
Polure Polfix polyurethane adhesive, which provides high strength and flexibility, should be used during installation. Silicone-based adhesives should be avoided as they may loosen over time. Mechanical screwing is also mandatory.
Does the product need to be sanded before painting?
The product comes factory-primed with a smooth surface. However, after filling and concealing screw holes during installation, the joints and filled areas should be smoothed out using 180-220 grit sandpaper.
What are its advantages compared to plaster pediments?
Plaster pediments are very heavy and can crumble or crack over time. In contrast, the polyurethane crown is lightweight, putting only a limited load on the building structure, resists breakage and moisture, and is much faster to install.
Is it mandatory to apply an additional coat of primer?
The factory primer on the product is ready to receive paint. However, since paint manufacturers do not guarantee applications done without their own primers, applying an additional primer coat is entirely at the customer's discretion.
