The P80112 decorative pediment is a premium architectural element designed to introduce classical symmetry and relief detailing to high-end interiors and exterior facades. Inspired by classical Greek and Roman ornamentation, this beautifully proportioned crown serves as an impressive focal point over doors, window frames, mirrors, and fireplaces. It provides an immediate sense of structural depth, transforming plain surfaces into sophisticated architectural statements.
Engineered with a thickness of 36 mm, a generous width of 779 mm, and a height of 382 mm, this pediment is ideally scaled for standard and grand doorways alike. It is manufactured from high-density rigid polyurethane (150-220 kg/m³), giving it a solid feel comparable to hardwood while remaining remarkably lightweight. Thanks to its closed-cell physical structure, the material absorbs virtually no moisture (less than 1%), preventing warping, cracking, or swelling, even in humid bathrooms or exposed outdoor settings.
Visually, the P80112 showcases a magnificent central palmette or shell-like motif that radiates outwards, anchored by a smooth circular central medallion. Symmetrical acanthus leaf scrolls cascade gracefully to the sides, ending in delicate, tight volutes. The precision of the molding captures every subtle ridge and curve with sharp definition, mimicking the expensive craftsmanship of traditional hand-carved stone or wood without the associated weight, cost, or fragility.
This versatile decorative piece is highly favored by architects and interior designers for defining transition zones. It can be positioned directly above door architraves to elevate entryways, placed over tall windows to create a stately exterior facade, or integrated into custom cabinetry and fireplace mantels. When used outdoors, it must be coated with a high-quality UV-resistant paint to protect it from sun exposure and preserve its pristine appearance over time.
Each piece arrives pre-treated with a white factory primer that prepares the surface for painting. While this factory layer facilitates initial paint adhesion, paint manufacturers often require their own specialized primers to honor their paint warranties; therefore, applying an additional primer layer is optional and left to the installer's discretion. Polure does not guarantee or accept liability for the performance of third-party paints. For a secure installation, apply polyurethane (PU) mounting adhesive to the back, press firmly onto a clean, dry wall, and secure mechanically with screws. Finish by filling screw holes with acrylic putty, sanding, and applying your topcoat.

- Do not use silicone adhesives during any part of this installation
- Maintenance of this rigid material is exceptionally straightforward
- For interior applications, simply wipe the surface periodically with a soft, damp cloth to remove dust
- For exterior installations, the pediment can be washed with low-pressure water if needed; however, avoid high-pressure power washers or harsh, abrasive chemical cleaners that could damage the paint layer
- We recommend inspecting the exterior paint coat annually for any weathering, particularly on south-facing walls, and applying a fresh topcoat when necessary to maintain UV protection
Can the P80112 pediment be used on outdoor building facades?
Yes, this pediment is fully suitable for outdoor use. Assess water and moisture exposure using the product technical data, surface finish and installation details. However, because raw polyurethane can yellow under direct sunlight, it is mandatory to paint the product with a high-quality, UV-resistant exterior paint to ensure long-term color stability and protection.
What is the best way to paint this decorative crown?
The product comes factory-primed, which provides an initial surface for paint adhesion. Depending on your paint manufacturer's warranty requirements, you may choose to apply an additional primer coat, though this is optional. You can paint the pediment using high-quality water-based (acrylic) or synthetic paints. For a classic look, decorative techniques like gold leafing, patination, or faux wood graining can also be applied.
How heavy is the P80112 pediment and is it easy to install?
Despite its large size of 779x382 mm and detailed carving, the pediment is remarkably lightweight due to its 150-220 kg/m³ density. This makes it much easier and safer to install than heavy plaster or solid wood alternatives. A single installer can easily manage the mounting process using polyurethane (PU) mounting adhesive and a few mechanical screws.
Why should I choose polyurethane over traditional plaster or wood?
Polyurethane offers major advantages: unlike plaster, it is shatterproof, does not crumble, and is extremely lightweight. Unlike natural wood, it is highly resistant to moisture, insects, and wood rot, helping to reduce warping or cracking over time. This makes it a highly durable, low-maintenance, and cost-effective solution for both indoor and outdoor luxury detailing.
Can this pediment be customized or cut to fit a smaller space?
While the P80112 is a solid, molded piece with a symmetrical design that is best kept intact, it can be easily sawed, drilled, or sanded using standard woodworking tools if minor adjustments are needed at the edges. Any cut edges should be sealed, filled with putty, and sanded smooth before applying the final paint coats.
