P81373 is a minimalist decorative element designed to bring indirect lighting concepts to life in modern interior projects. By concealing LED strips at the wall-to-ceiling junctions, it provides spaces with a soft, glare-free, and homogeneous light distribution. Compared to plaster alternatives, its non-cracking, shatterproof structure, and superior impact resistance over EPS foam products ensure long-lasting durability.
From a technical standpoint, the product is manufactured from high-density rigid polyurethane with a density of 150-220 kg/m³ (production target ~160 kg/m³). Include the product weight and fixing loads when assessing the substrate and supporting structure. It features a height of 80 mm, a projection of 50 mm from the wall, and a standard length of 2400 mm. Thanks to its closed-cell structure, its water absorption rate is below 1%, preventing swelling, rotting, or dimensional distortion even in high-humidity areas like bathrooms and kitchens.
Featuring a smooth, elegant curve, the profile aesthetically conceals the light source while allowing light to glide softly across the ceiling. The product is shipped factory-primed with a special white coating. While this primer prepares the surface for the topcoat, paint manufacturers often do not guarantee applications done without their own primers; therefore, applying an additional primer coat is entirely optional and left to the user's discretion to enhance the durability of the final coat.
Offering a wide range of applications, P81373 is highly preferred in living rooms, behind bedroom headboards, hotel corridors, office ceilings, and modern restaurant designs. When applied with correct painting and installation techniques, its moisture resistance allows it to be safely used for creating concealed lighting details under exterior eaves as well as indoors.
During installation, after making 45-degree miter cuts on a clean, dry surface, Polure Polfix adhesive is applied to the back surfaces and joints. For a secure installation, mechanical fastening with screws is mandatory. Once the screw heads and joints are filled with putty and smoothed with 180-220 grit sandpaper, the process is completed with an optional primer and two coats of water-based or synthetic paint.
- The P81373 indirect lighting profile is ideal for creating a modern light band at wall-to-ceiling intersections
- In residential spaces, it integrates seamlessly with suspended ceiling systems in living rooms, hallways, entryways, and bedrooms to create a cozy, relaxing ambiance
- In commercial areas, it delivers a prestigious look in hotel lobbies, restaurant ceilings, showrooms, and office meeting rooms
- Assess water and moisture exposure using the product technical data, surface finish and installation details
- When used for under-eave lighting in exterior projects, it must be coated with a UV-resistant exterior paint to protect it from sunlight
- The application surface must be completely free of dust, moisture, and dirt
- Cut the profile ends at a 45-degree angle using a miter box
- Apply Polure Polfix adhesive to the joints and the surfaces contacting the wall, then press the profile into place
- While the adhesive cures, mechanical fastening with screws is required to prevent slippage and ensure a perfect fit
- Fill screw holes and joints with acrylic filler
- Once dry, smooth the filled areas with 180-220 grit sandpaper
- To meet topcoat warranty conditions of paint manufacturers, an additional coat of primer can be applied if preferred, followed by at least two coats of water-based or synthetic paint to complete the installation
- Thanks to the durability of polyurethane, cleaning is exceptionally easy
- Accumulated dust can be easily wiped away with a soft, slightly damp cloth
- Avoid using abrasive detergents, hydrochloric acid, or thinners during cleaning, as these harsh acidic or alkaline chemicals can damage the surface primer and paint
- If you wish to refresh or change the color years later, you can simply sand the surface lightly and repaint it in any color of your choice
Which types of LED strips are suitable for the P81373 indirect lighting profile?
The inner channel of the profile is wide enough to easily accommodate standard single-chip, triple-chip, or COB LED strips. To help dissipate heat and extend the lifespan of the LED strip, we recommend placing a slim aluminum profile inside the channel and mounting the strip onto it.
Will it sag or deform in high-humidity areas like bathrooms and kitchens?
No, it will not. The product is manufactured from high-density rigid polyurethane (150-220 kg/m³) with a closed-cell structure. Since its water absorption rate is below 1%, it remains unaffected by moisture or steam, preventing any swelling, sagging, or deformation.
What are the installation advantages compared to plaster cornices?
Plaster products are heavy and fragile, carrying a high risk of cracking during installation. In contrast, P81373 is extremely lightweight and flexible, making it easy to transport without risk of breakage. It installs much faster and cleaner using Polure Polfix adhesive combined with mechanical screwing.
Is the product suitable for exterior use under building eaves?
Yes, it is suitable. However, unpainted polyurethane can yellow over time when exposed to solar UV rays. For exterior applications, the product must be coated with a high-quality, UV-resistant exterior paint after installation.
Do I have to apply an additional coat of primer before installation?
The product is shipped factory-primed. However, paint brands do not guarantee against peeling if their own primers are not used. Therefore, while an extra coat of primer is not mandatory, it is recommended based on customer preference to secure the paint warranty and ensure long-term durability.
