The P88091 cornice profile is a premium architectural transition element designed to bridge the gap between walls and ceilings with refined geometry. Featuring a balanced, deep concave curve accented by crisp, stepped linear borders, this profile creates a subtle shadow play that enhances the perceived height and volume of any room. It offers an ideal aesthetic solution for projects looking to combine traditional architectural depth with clean, contemporary lines.
Manufactured from high-density rigid polyurethane (150-220 kg/m³), this molding delivers wood-like surface hardness while remaining remarkably lightweight. With dimensions of 110 mm projection, 150 mm height, and a generous 2400 mm length, it provides excellent structural stability without adding unnecessary dead load to your ceiling. The material's dimensional stability has been tested between -20 °C and +70 °C, ensuring no warping, shrinking, or expansion over time.
Unlike traditional gypsum or plaster alternatives, this profile features a closed-cell physical structure with a water absorption rate of less than 1%. This makes it moisture-resistant and helps reduce the risk of rot and insect damage, allowing for seamless integration into high-humidity environments. The product arrives with a factory-applied white primer coat, which prepares the surface for final painting.
Whether specified for residential living rooms, high-end hotel suites, or commercial offices, the P88091 profile offers versatile application. It can also be utilized for exterior soffits and eaves, provided it is finished with a UV-resistant coating to protect the underlying material from sunlight exposure.
Installation is straightforward and efficient. Secure the profiles using polyurethane (PU) assembly adhesive along the mounting tracks—never use silicone—and reinforce with mechanical screws for permanent stability. Once the joints are filled, sanded with 180-220 grit paper, and coated with your choice of water-based or synthetic paint, the result is a perfectly continuous, crack-free finish.
- The P88091 cornice profile is designed for both interior and exterior architectural transitions
- Indoors, it serves as an excellent decorative crown molding for residential living spaces, bedrooms, and grand hallways
- Assess water and moisture exposure using the product technical data, surface finish and installation details
- For commercial projects, it adds a sophisticated touch to hotel lobbies, office boardrooms, and restaurant dining areas
- When painted with a UV-stable exterior paint, it can be safely used on building facades, under roof eaves, or to finish porch ceilings
- Ensure the installation surface is dry, clean, and free of dust
- Cut the profiles to size, using 45-degree miter cuts for corners
- Apply a continuous bead of polyurethane (PU) assembly adhesive to the mounting surfaces of the profile
- Do not use silicone
- Press the molding firmly into place at the wall-ceiling junction and secure it mechanically using screws or finishing nails
- Once the adhesive has cured, fill all joint lines and screw heads with high-quality filler
- Sand the filled areas smooth with 180-220 grit sandpaper
- Finish with two coats of high-quality water-based or solvent-based paint
- Note that while the factory primer prepares the surface, applying an additional paint-specific primer is optional and subject to your paint manufacturer's guidelines
- This polyurethane profile requires minimal maintenance
- For routine cleaning, simply wipe down the surface with a damp cloth or a feather duster
- For deeper cleaning in kitchen or outdoor settings, a mild, non-abrasive household detergent can be used
- Avoid harsh chemical solvents, acidic cleaners, or abrasive scrubbing pads, as these can damage the paint finish
- In the event of minor physical impact, the surface can be easily restored by applying a standard acrylic compound, sanding it smooth once dry, and touching it up with the original paint
Can the P88091 profile be installed in damp environments like bathrooms?
Yes, absolutely. Assess water and moisture exposure using the product technical data, surface finish and installation details.
Is it necessary to apply an extra primer before painting?
The product comes pre-primed from the factory to prepare the surface for painting. However, because paint manufacturers only guarantee their topcoats when applied over their own proprietary priming systems, applying an additional primer is an optional step left to the client's discretion.
What type of adhesive is recommended for mounting?
You must use a high-quality polyurethane (PU) assembly adhesive for a strong, structural bond. Silicone adhesives must be avoided as they do not provide the necessary adhesion or stability for this material over time.
How does this product compare to traditional plaster cornices?
Polyurethane is significantly lighter, making installation safer and faster. Unlike plaster, it is shatterproof, does not crack during building settling, and can be easily cut with standard woodworking tools.
Can this cornice molding be used on exterior facades?
Yes, it is suitable for outdoor use, such as under roof eaves or on porch ceilings. However, you must paint the profile with a UV-resistant exterior paint to protect it from yellowing under direct sunlight.
