P81378A is an exclusive polyurethane indirect lighting profile frequently preferred in modern interior designs, bringing an aesthetic and functional touch to the intersection of walls and ceilings. This product is engineered to create a glare-free, homogeneous lighting scheme. By softening the overall atmosphere of interior spaces, it evokes a more spacious and contemporary sense of depth. Its minimalist lines seamlessly complement next-generation decoration trends.
Standing out with its technical performance and material quality, this profile measures 97 mm in width, 200 mm in height, and 2400 mm in length. Its high-density (150-220 kg/m³) rigid polyurethane structure provides wood-like durability while remaining remarkably lightweight. This lightweight nature prevents extra load on the building structure during ceiling installations, ensuring structural safety and ease of application. With a water absorption rate of less than 1%, it is highly resistant to moisture and water, preventing swelling, cracking, or rotting even in humid environments like bathrooms and indoor pools.
In terms of visual design, the P81378A model embodies modern minimalism with its smooth and sleek surface. The dedicated lighting channel at the top of the profile allows LED strips to be positioned at the perfect angle. Free of any exaggerated classical ornamentation, these sharp geometric lines ensure that light is distributed flawlessly across the ceiling surface, creating elegant shadow plays.
Highly versatile in application, this decorative element finds its place in modern living room ceilings, bedroom headboard lighting, luxury hotel lobbies, and prestigious office projects. Thanks to its water-resistant structure, it is also utilized as concept lighting in wellness and spa centers. For exterior designs, it can be painted with UV-resistant exterior paint to protect it from the damaging effects of sunlight and used under eaves or in sheltered entranceways.
Compared to traditional plaster cornices, it is extremely impact-resistant, reducing the risk of breaking or crumbling during transport and installation. The installation process is clean and fast. After cleaning the application surface, the profiles, cut at 45-degree angles, should be fixed to the surface using Polure Polfix adhesive and mechanically supported with screws. Once the screw heads and joints are puttied and smoothed with 180-220 grit sandpaper, the surface is ready for paint.
The product is delivered from the factory with a white primer coat applied. This factory primer facilitates the adhesion of the topcoat. However, considering the paint manufacturers' own primer standards and warranty conditions, applying an additional coat of primer is entirely at the user's discretion. Polure does not assume responsibility for the performance and durability of the applied paints.
- The P81378A polyurethane indirect lighting profile is designed to create an elegant lighting band at wall-to-ceiling junctions
- Its wide range of applications includes modern living room ceilings, bedrooms where a soft and relaxing ambiance is desired, corridors, and hallways
- In commercial projects, it serves as a sophisticated light channel in hotel lobbies, restaurant ceiling details, modern office meeting rooms, and retail window displays
- Thanks to its water and moisture absorption rate of under 1%, it can be safely installed in high-humidity areas such as bathrooms, spas, and indoor pools without swelling or peeling
- Furthermore, it offers an innovative outdoor lighting solution under eaves, veranda ceilings, or facade projections, provided it is coated with a UV-resistant exterior paint
- With its generous vertical (20 cm) and horizontal (9.7 cm) dimensions, it is an excellent architectural tool to emphasize ceiling height and create a sense of depth in large-volume spaces
- The installation of the P81378A model must be carried out on clean, dry, and smooth surfaces
- The corner joints of the profiles are precisely cut using 45-degree miter saws
- Only Polure Polfix polyurethane adhesive should be used for bonding; silicone-based adhesives must be avoided
- To ensure safety in ceiling applications, mechanical fastening with screws is mandatory in addition to the adhesive
- Screw heads and profile joints are filled with high-quality acrylic putty
- Once dry, a smooth surface is achieved by sanding with 180-220 grit sandpaper
- Although the factory-applied primer prepares the surface for the topcoat, applying an additional primer coat is optional, depending on the paint manufacturers' warranty conditions
- In the final step, the installation is completed by applying at least two coats of water-based or synthetic paint
- Maintaining the polyurethane indirect lighting profile is exceptionally practical
- Thanks to its smooth and non-porous surface, it has a low dust-retention rate
- For routine cleaning, wiping with a slightly damp, soft cloth is sufficient
- Heavy chemical cleaners containing thinners, bleach, or abrasive particles that could damage the surface structure and paint must be strictly avoided
- In case of minor staining or color fading over time, the surface can be lightly sanded and repainted to easily restore its original appearance
- Highly resistant to physical impacts, this material retains its shape and color for many years without requiring intensive maintenance
Can it be used on exteriors or in bathrooms?
Yes, our product is highly resistant to water and moisture, making it perfectly safe for use in areas like bathrooms and spas. For exterior applications, such as under verandas or eaves, a UV-resistant exterior paint must be applied to protect it from the degrading effects of sunlight.
What are its advantages compared to plaster cornices?
Plaster materials are heavy, fragile, and sensitive to moisture. In contrast, polyurethane is extremely lightweight with a density of 150-220 kg/m³, adding no significant load to the building structure, and it is highly resistant to impacts, cracking, or breaking. Additionally, its installation is much cleaner and faster.
Can I use the product without painting, and is an extra primer required?
Our product is shipped from the factory with a white primer coat. However, since unpainted polyurethane may yellow over time, painting is highly recommended. While the factory primer prepares the surface, applying an additional primer coat is optional and depends on your paint brand's warranty terms.
Where and how are the LED strips placed?
The P81378A model features a dedicated channel/housing at the top for LED strips. Self-adhesive LED strips can be easily mounted inside this channel. The profile's design ensures that light reflects onto the ceiling evenly and without causing glare.
Which adhesive should I use for installation?
For perfect adhesion and long-lasting durability, only Polure Polfix polyurethane adhesive should be used during installation. Silicone or similar flexible adhesives should be avoided, as they may stretch over time and cause joints to open.
