The P81376 indirect lighting profile offers a sophisticated architectural solution for modern interior lighting designs. Engineered to house LED strips seamlessly, this profile reflects light softly against the ceiling, eliminating harsh glares and creating a warm, welcoming atmosphere. It serves as an excellent, cost-effective alternative to complex drywall drop ceilings for achieving a modern floating ceiling effect.
Crafted from high-density rigid polyurethane (150-220 kg/m³), this profile combines the structural strength of hardwood with a lightweight design. Measuring 135 mm in height, 85 mm in width, and 2400 mm in length, its substantial size makes it perfect for medium to spacious rooms. The closed-cell structure provides high resistance to moisture, helping prevent the profile from warping, cracking, or rotting over time.
Featuring an elegant S-curve contour with a smooth, flat surface, the P81376 is visually striking yet minimalist. The curved front lip cleverly conceals the LED channel while maximizing light distribution. The factory-applied primer provides an optimal surface texture, preparing the profile for custom color coating to match any interior palette.
This interior lighting profile is highly versatile, finding its place in residential spaces like living rooms, master bedrooms, and dining halls, as well as commercial environments such as luxury hotels, restaurants, and corporate offices. Compared to heavy plaster or moisture-sensitive MDF, this polyurethane alternative is remarkably easy to install and handle.
Installation requires preparing a clean surface, cutting precise 45-degree miter joints, and securing the profile with a high-quality polyurethane (PU) mounting adhesive along with mechanical screw reinforcement. Once mounted, seams are filled, sanded, and painted to achieve a flawless, integrated look.
- The P81376 is specifically designed as an interior indirect lighting coving profile
- It is ideal for living room ceiling borders, creating a soft glowing ambiance that enhances spatial depth
- In bedrooms, it provides a relaxing, glare-free light source perfect for evening relaxation
- It is also widely used in commercial settings such as hotel lobbies, upscale restaurants, and executive offices to define ceiling perimeters with modern architectural lighting
- Due to its superior moisture resistance, it can safely be installed in high-humidity indoor areas like master bathrooms or kitchen ceilings where traditional plaster or MDF would degrade
- Note: This product is strictly for indoor use and should not be installed on exterior facades
- Ensure the mounting surface is clean, dry, and structurally sound
- Measure and mark the installation line on the wall and ceiling
- Cut the 2.4-meter profiles using a fine-toothed saw and a miter box for clean 45-degree corner joints
- Apply a continuous bead of polyurethane (PU) mounting adhesive to the mounting flanges that contact the wall and ceiling
- Press the profile firmly into place and secure it mechanically with non-corrosive screws to prevent slippage while the adhesive cures
- Wipe away any excess adhesive immediately
- After curing, fill screw holes and joints with an appropriate interior joint filler or acrylic mastic
- Once dry, sand the joints smoothly with 180-220 grit sandpaper
- Apply a suitable paint primer (optional but recommended by paint manufacturers for warranty purposes) followed by two coats of water-based or synthetic paint
- The smooth, non-porous polyurethane surface of the P81376 makes maintenance exceptionally simple
- For regular cleaning, gently wipe the profile with a dry or slightly damp microfibre cloth to remove accumulated dust
- Avoid using harsh chemical cleaners, abrasive pads, or solvents, as these may damage the painted finish
- Assess water and moisture exposure using the product technical data, surface finish and installation details
- The profile can be easily repainted in the future if you decide to change the room's color scheme
Can this profile be used in wet areas like bathrooms?
Assess water and moisture exposure using the product technical data, surface finish and installation details.
What type of adhesive should be used for installation?
You must use a premium polyurethane (PU) mounting adhesive for bonding. Do not use standard silicone or hot glues, as they do not provide the necessary long-term structural bond. Mechanical screw fastening is also required.
Do I need to apply an extra primer before painting?
The profile comes with a factory-applied primer that prepares the surface for painting. However, paint manufacturers often require their own primers to validate paint warranties, so applying an additional primer is optional but highly recommended.
How does polyurethane compare to plaster or gypsum covings?
Polyurethane is significantly lighter, less prone to shattering, and moisture-resistant. Unlike plaster, which is heavy, fragile, and prone to cracking, PU profiles are easy to transport, cut, and install without professional masonry tools.
Can I use this product on an outdoor terrace or facade?
No, the P81376 model is strictly designed and rated for indoor applications. It does not have the necessary UV stabilizers for outdoor exposure, and should not be used on exterior facades.
