The P81354 plain cornice moulding offers a modern and minimalist transition at the intersection of walls and ceilings. With its impressive height of 218 mm, it creates a strong vertical statement in spacious rooms with high ceilings, while its 41 mm projection defines elegant boundaries without reducing the room's volume. The clean, smooth surface design avoids complex details, making it the perfect choice for architects and interior designers aiming to bring a spacious, serene atmosphere to contemporary spaces.
Manufactured from high-density rigid polyurethane (150-220 kg/m³), this product offers a wood-like hardness while remaining remarkably lightweight. Thanks to its closed-cell structure, it is moisture-resistant. This helps the moulding retain its shape over time, whether installed in wet areas like bathrooms and kitchens, or exposed to harsh outdoor conditions. Unlike fragile plaster or moisture-sensitive wood, its durable structure guarantees a long lifespan without cracking or crumbling.
A closer look at the profile cross-section reveals a balanced harmony between the subtle stepped chamfer details at the top and the wide flat surface at the bottom. These geometric transitions sharply define wall-to-ceiling lines in both modern and neo-classical interior styles. The product is shipped factory-primed in white. This factory primer prepares the surface for the final coat, ensuring excellent paint adhesion; however, due to varying standards among paint manufacturers, applying an additional primer remains an optional choice for the customer.
This wide ceiling profile delivers outstanding results as a finishing element in spacious residential living rooms, bedrooms, and hallways. It is also highly favored in prestigious commercial projects, including hotel lobbies, modern restaurants, large offices, and gallery spaces. Thanks to its water resistance, it can be safely installed outdoors under eaves or as a complementary element for exterior belt courses. For outdoor applications, using UV-resistant paint is mandatory to prevent yellowing over time.
During installation, miter cuts are made at a 45-degree angle on a clean, dry surface before application. For secure bonding, the high-strength Polure Polfix adhesive must be used, and the moulding should be mechanically locked to the wall and ceiling using screws. Once joints and screw heads are filled with joint compound and sanded smooth with 180-220 grit sandpaper, applying two coats of paint completes the seamless look. Compared to traditional plaster cornices, this polyurethane-based profile offers a clean, fast, and dust-free installation process.
- The P81354 cornice moulding is specifically designed to provide an aesthetic transition at wall-to-ceiling intersections
- With its wide vertical height of 218 mm, it serves as an excellent ceiling finishing profile, particularly for high-ceilinged living rooms, spacious hallways, hotel lobbies, and prestigious office projects
- Its wide, flat surface blends seamlessly with modern and minimalist designs, while also functioning as an upper or lower border for indirect LED lighting applications
- Highly resistant to water and humidity, it is safely used in moisture-prone indoor areas such as bathrooms, kitchens, and spa facilities
- For exterior applications, it acts as an elegant architectural finishing element under eaves or at the upper joints of belt courses
- It creates clean, modern lines above windows or along rooflines on villa and residential facades
- When used outdoors, painting it with UV-protected exterior paint preserves its lifespan and color quality
- The application surface must be clean, dry, and free of dust
- Cornice profiles should be cut at a 45-degree angle at corner joints using a miter saw
- During installation, only Polure Polfix adhesive must be used; silicone-based adhesives should be strictly avoided
- Apply Polfix adhesive to the mounting channels on the back of the profile before positioning it on the wall and ceiling
- Due to its wide and high-profile design, mechanical fastening with screws is mandatory
- Once the adhesive has cured, cover screw heads and joints with a high-quality acrylic filler
- Sand the dried filler smooth using 180-220 grit sandpaper
- Finally, if desired, apply an additional primer and finish with at least two coats of water-based or synthetic paint
- Thanks to its smooth surface, the polyurethane cornice profile requires minimal maintenance
- Indoor dust accumulation can be easily cleaned with a slightly damp cloth or a soft brush
- Avoid using abrasive chemicals, acidic solvents, or harsh scrubbing pads that could damage the surface
- For outdoor installations, we recommend checking the paint layer once a year and performing local touch-ups if necessary
- Do not wash the profiles directly with high-pressure water sprayers during cleaning
Is it suitable for exterior use?
Yes, thanks to its resistance to water, moisture, and harsh weather conditions, the P81354 cornice moulding can be safely used on exteriors. However, when installed outdoors, it must be painted with UV-resistant exterior paint to protect it from the yellowing effects of sunlight.
Which adhesive should I use for installation?
For a secure and long-lasting installation, only Polure Polfix adhesive should be used during the bonding stage. Silicone-based adhesives should be avoided as they may lose adhesion over time on polyurethane. Due to its wide profile, mechanical fastening with screws is also required.
Can the product be used directly without painting?
The product is shipped factory-primed in white. However, painting is highly recommended to protect the material from UV rays and to match the color scheme of your space. While the factory primer prepares the surface, applying an additional primer remains optional at the customer's discretion, depending on the paint manufacturer's warranty terms.
What are its advantages compared to plaster cornices?
Plaster cornices can absorb moisture over time, becoming heavy, cracking, and crumbling. Assess water and moisture exposure using the product technical data, surface finish and installation details. They do not add extra load to the building structure, and their installation is much cleaner and faster.
Is a height of 218 mm suitable for small rooms?
With a vertical height of 218 mm, this model is a wide-profile product. In very small rooms with low ceilings, it may make the space feel slightly confined. However, in high-ceilinged living rooms, wide hallways, and large spaces like lobbies, it enhances the sense of depth, providing an exceptionally elegant and balanced look.
