The P2839 is a majestic architectural pediment designed to provide an elegant finishing touch above doors, windows, and main entryways. With a length of 2400 mm, a peak height of 375 mm, and a depth of 255 mm, it creates a striking visual focal point on expansive facades and high-ceilinged interiors. The central oval medallion motif, combined with symmetrical spiral and acanthus leaf patterns sweeping outward, embodies the finest elements of classical architecture.
Crafted from high-density rigid polymer (150-220 kg/m³), this product offers the durability of wood but in a much lighter alternative. Thanks to its closed-cell structure, its water absorption rate is virtually zero, completely preventing swelling, rotting, or cracking in humid climates and exterior applications. Unlike fragile plaster alternatives, this durable architectural element carries no risk of breakage, promising long-lasting performance.
Delivered with a factory-applied white primer, the surface is ready for the final topcoat. However, since paint manufacturers typically do not guarantee applications done without their own primers, applying an additional primer coat before the final paint is entirely at the user's discretion. For outdoor applications, UV-resistant exterior paints must be used to protect the product from the harsh effects of sunlight.
During installation, Polure Polfix adhesive should be applied to the cleaned surface, followed by mechanical fastening with screws. Once screw heads and joints are filled with putty and sanded smooth, the final painting can begin. This simple installation process offers significant savings in labor and time compared to heavy stone or concrete lintels.
- This large-scale architectural pediment is primarily used as a crowning element above windows on exterior facades and grand villa entrance doors
- Indoors, it adds magnificent depth to hotel lobbies, spacious living rooms, over-mantel fireplace designs, and classical-style headboard wall paneling
- Thanks to its generous width, it easily rests atop two vertical window casing profiles, providing a seamless modular integration
- Ensure the application surface is clean, dry, and free of dust
- After making any necessary miter cuts, apply Polure Polfix adhesive to the back of the product
- Once positioned on the wall, mechanically secure the pediment with dowels and screws to prevent slipping while drying
- Fill screw holes and joints with acrylic putty, and sand smooth with 180-220 grit sandpaper once dry
- Finally, apply an optional extra coat of primer followed by two coats of paint
- It features a smooth surface that can be easily cleaned with a damp cloth
- For exterior applications, we recommend inspecting the joints and paint layer once a year to extend the lifespan of the finish
- While it can be washed with high-pressure water, abrasive chemical cleaners should be avoided
- In case of any impact damage, it can be easily restored to its original state using putty and touch-up paint
Will the P2839 pediment model be affected by outdoor weather conditions?
No, the product is manufactured from high-density rigid polymer (150-220 kg/m³) and has a water absorption rate of less than 1%. It is completely unaffected by rain, snow, frost, and high humidity, meaning it will not rot or swell. For long-lasting exterior performance, it must be painted with UV-resistant paint after installation.
Can the polyurethane pediment be painted directly after installation?
The product is shipped factory-primed and the surface is ready for paint. However, since paint manufacturers do not guarantee applications done without their own primers, applying an additional coat of primer is entirely at the customer's discretion. For optimal paint adhesion and durability, an extra primer coat is recommended.
What are its advantages compared to plaster or wood pediments?
Unlike fragile plaster, it does not break or chip during transport and installation. Unlike wood, it does not warp, rot, or attract pests when exposed to moisture. Being significantly lighter, it does not add static load to the building and allows for exceptionally fast installation.
Which adhesive should be used during installation?
To ensure a secure bond, only Polure Polfix polyurethane adhesive should be used. Silicone or similar flexible adhesives should be avoided as they can loosen over time. In addition to the adhesive, mechanical fastening with screws is mandatory.
Does the weight of the product add an extra load to the building?
No, the product is extremely lightweight compared to stone or concrete alternatives. Thanks to its density of 150-220 kg/m³, it adds no static load to the structure and ensures easier handling for installers, improving safety on site.
