The P85016C moulding corner element is a functional decorative product designed to create aesthetic frames on wall and ceiling surfaces. Eliminating the hassle of mitering and cutting when connecting straight moulding profiles, this curved corner piece ensures a smooth and balanced transition. It is an ideal architectural component to enhance the sense of depth in interior design and bring blank walls to life.
The product measures 255x255 mm in width and 22 mm in thickness. Manufactured from high-density rigid polyurethane (150-220 kg/m³), this corner profile offers a surface hardness comparable to wood, providing high resistance to impacts and wear. Thanks to its closed-cell structure, its water absorption rate is below one percent, preventing swelling, cracking, or shrinking even in humid environments. It fully retains its shape within a temperature range of -100 °C / +80 °C.
In terms of visual design, simplicity takes center stage. The stepped straight lines on the outer edges merge with a wide inner circular curve, creating a minimalist profile that seamlessly blends with modern and neoclassical styles. It features a clean, smooth surface texture thanks to its factory-applied primer. This curved structure beautifully transforms the sharp, angular turns of straight mouldings into an elegant circular form.
Offering a wide range of applications, this corner element is highly preferred for wall paneling in living rooms, headboard framing in bedrooms, chair rail transitions in hallways, and decorative ceiling medallion borders. Furthermore, due to its water resistance, it can be safely used on bathroom walls and, when coated with suitable UV-resistant exterior paint, on the corners of window or door casing frames on building facades.
For installation, Polure Polfix adhesive is applied to the cleaned surface. Mechanical fastening with screws at the joints of the profiles is essential for long-lasting durability. Once the screw holes and joints are filled with putty and sanded, the painting process can begin. Although the factory primer enhances paint adhesion, applying an additional primer coat is optional depending on the paint manufacturer's warranty terms. Being extremely lightweight compared to plaster alternatives, it speeds up installation and reduces structural load.
- This moulding corner profile offers a wide range of applications for both interior and exterior spaces
- Indoors, it is ideal for creating wall frames (boiserie) in areas such as living rooms, hallways, bedrooms, and lobbies
- On ceilings, it provides elegant circular transitions for decorative ceiling panels and chandelier frame corners
- Thanks to its complete resistance to water and moisture, it can be safely used on bathroom and kitchen walls
- For exterior applications, it delivers a durable and decorative look on the corners of window and door casing frames, provided it is coated with UV-resistant exterior paint
- Ensure the application surface is clean, dry, and smooth
- Apply Polure Polfix adhesive to the back of the moulding corner profile and position it on the wall
- After aligning the joints with the straight moulding profiles, secure them mechanically using screws
- Cover the screw heads and joints with acrylic exterior putty
- Once the putty is dry, sand the surface smooth using 180-220 grit sandpaper
- Complete the installation by optionally applying an additional primer and painting with two coats of water-based or synthetic paint
- Cleaning the product is highly practical
- It can be easily wiped clean with a damp, soft cloth without damaging the surface
- Avoid using abrasive powder chemicals, acidic substances, or harsh sponges during cleaning
- If you wish to change the color or refresh its appearance years later, you can lightly sand the surface and repaint it
Can polyurethane moulding corners be used on exterior facades?
Yes, thanks to its closed-cell structure, the P85016C moulding corner is unaffected by weather conditions, rain, and moisture. The only point to consider when using it outdoors is to paint the material with UV-resistant exterior paint to protect it from the sun's UV rays.
Which adhesive should be used for installation and is screwing mandatory?
During installation, Polure Polfix adhesive must be applied to the back surface. Silicone-based adhesives should be avoided as they may stretch over time. Mechanical fastening with screws is mandatory to ensure the material fits perfectly against the wall and does not pull away over time.
Does the product come painted from the factory, is primer application required?
The product is shipped from the factory with a protective white primer coat. This primer prepares the surface for the final coat of paint. However, due to the varying primer standards of paint manufacturers, applying an additional primer coat before the final paint is optional and left to the customer's preference.
What are the advantages compared to plaster or wood moulding corners?
Rigid polyurethane is not fragile like plaster and will not crack during transport or installation. Unlike wood, it is unaffected by moisture, preventing rotting, insect infestation, or warping. Thanks to its density of 150-220 kg/m³ (production target ~160 kg/m³), it is both lightweight and highly resistant to impacts.
How does the thickness of P85016C moulding corner align with straight mouldings?
The product has a thickness (projection) of 22 mm. This thickness is designed to provide a seamless, flush joint with 22 mm thick straight wall moulding profiles. When the joints are puttied and sanded during installation, a continuous, single-piece appearance is achieved between the moulding and the corner.
