Polyurethane Decorative Wall Border and Cornice Profile

The P85407 is a high-performance polyurethane border profile designed to establish crisp, architectural transitions on walls and ceilings. Engineered for both interior and exterior applications, this premium profile functions excellently as a chair rail, wall divider, or subtle cornice. Unlike traditional plaster, which is heavy and prone to cracking, or MDF, which absorbs moisture, this advanced material offers a durable, lightweight alternative that simplifies installation while maintaining sharp, defined lines.

With a rigid polyurethane density of 150-200 kg/m³, this profile matches the hardness and structural integrity of high-quality wood while remaining significantly lighter. This lightweight composition ensures that it adds no unnecessary load to your walls or ceilings. Its closed-cell structure guarantees a water absorption rate of under 1%, making it completely waterproof and immune to rot, swelling, or insect infestation. This dimensional stability ensures the profile retains its exact shape and form throughout its lifespan, even in high-humidity zones.

Visually, the P85407 features an attractive, stepped architectural design. It transitions from a delicate top step into a deep, smooth concave cove, finishing with a small rounded bead at the bottom. This specific geometry creates elegant shadow lines that define wall panels and frame ceilings with exceptional depth. The surface is delivered pre-treated with a white factory primer, which creates a smooth, receptive base. While this factory coating prepares the surface for finish painting, applying an additional primer before the final coat is optional and remains at the customer’s discretion based on the recommendations of their chosen paint manufacturer.

The versatility of the P85407 makes it suitable for a wide variety of architectural settings. Use it horizontally to divide walls in corridors, dining rooms, or hotel lobbies, allowing for beautiful dual-tone paint or wallpaper transitions. It can also be utilized on exterior facades as a horizontal band or belt course to break up large wall surfaces. When used outdoors, finishing the profile with a high-quality, UV-resistant paint is mandatory to prevent any yellowing or surface degradation from sun exposure.

Installing the profile is straightforward and efficient. Secure bonding is achieved by applying a premium polyurethane (PU) assembly adhesive along the rear mounting channels, supplemented with mechanical screws for permanent stability. The joints and screw heads are easily filled with standard acrylic filler, sanded flat, and finished with either water-based or synthetic paints to match your interior or exterior color scheme.
