Designed to simplify wall and ceiling paneling frames in interior design, this corner joint element brings flawless symmetry to architectural projects. It is engineered to completely eliminate the need for time-consuming and highly skilled 45-degree miter cuts during molding installation. Thanks to this functional piece, potential workmanship errors at corner joints are seamlessly hidden, significantly accelerating the installation process to deliver a professional finish.
From an engineering perspective, the product features an ideal size of 20x20 cm (200x200 mm) and a thickness of 2 cm (20 mm). It is manufactured from rigid polyurethane raw material with a density of 150-220 kg/m³ (production target ~160 kg/m³), offering a lightweight yet durable structure comparable to the hardness of wood. It provides an excellent alternative to fragile plaster or fragile polystyrene (EPS) foam. Thanks to its closed-cell structure, its water absorption rate is below one percent, meaning it will not shrink, expand, or crack even in humid environments.
The design features a soft, inward-curving arch form. The subtle, stepped profile lines along the edges elegantly complement simple and minimalist decor styles. Free of heavy patterns or dense reliefs, this smooth surface structure ensures a balanced, clean visual transition, making it particularly suitable for modern, contemporary, and neoclassical interior designs.
Highly versatile, this decorative element is frequently preferred for boiserie wall paneling in residential living rooms, bedrooms, entryways, and hallways. In commercial spaces, it is ideal for wall and ceiling framing in hotel lobbies, fine dining restaurants, and prestigious offices. It is also perfect for creating elegant corner transitions in headboard accent walls, large mirrors, and artwork frames. Suitable for interior use only, its high moisture resistance also makes it a reliable choice for bathrooms.
During installation, the surface must be dry and free of dust, and Polure Polfix adhesive should be used for bonding. In addition to adhesive, mechanical fastening with screws is required for a secure application. The factory-applied white primer coat ensures excellent adhesion for the final coat of paint. Due to varying standards among paint manufacturers, applying an additional primer is optional. The product can be painted in any desired color using water-based or synthetic paints.
- This product is used at the most critical joint points of interior wall and ceiling paneling designs
- It adds an aesthetic touch to corner transitions in boiserie (wall paneling) projects, particularly in living rooms, bedrooms, dining rooms, and hallways
- When combined with plain and simple wall moldings, it allows for the creation of modern or neoclassical frames
- It adds depth to ceilings when used in ceiling frame layouts in spacious hallways or prestigious areas like hotel lobbies
- It is ideal for framing behind headboards, or on wooden and painted surfaces behind TV units
- Additionally, it is frequently preferred to create elegant frame borders around large wall mirrors or custom artworks
- Due to its high moisture resistance, it can be safely installed for decorative purposes on bathroom and kitchen walls
- The wall or ceiling surface to be applied must be completely free of dust, dirt, and moisture
- The molding corner is aligned with the molding profiles and placed on the wall
- For bonding, only Polure Polfix adhesive must be used; silicone-based adhesives should be avoided
- Mechanical fastening with screws is mandatory to ensure a secure and permanent hold
- Any gaps at the joints between the moldings and the corner piece, as well as screw holes, should be filled with a fine joint filler
- Once the filler dries, sand it smooth with 180-220 grit sandpaper
- An additional coat of primer can be applied over the factory primer if desired; then, complete the process by applying at least two coats of water-based or synthetic paint
- Dust and stains on the surface can be easily cleaned with a soft, damp cloth
- Abrasive chemicals, acidic cleaners, or harsh sponges that could damage the paint should not be used during cleaning
- Thanks to its impact-resistant rigid structure, it is highly durable; however, minor deformations from accidental hard impacts can be easily restored to their original state with a light filler and local touch-up painting
- If you wish to change your decor in the future, the surface can be lightly sanded and easily repainted in different colors
Is it suitable for outdoor use?
No, this product is designed solely for interior decoration. It is not formulated to withstand outdoor weather conditions or direct sunlight (UV exposure).
What are its advantages compared to plaster or polystyrene corners?
Unlike plaster, it is not fragile and does not crumble during installation. Unlike polystyrene (EPS), it is not soft, making it highly impact-resistant. Additionally, its smooth surface and sharp lines offer a much more premium look.
Which adhesive should be used for installation?
Only Polure Polfix adhesive should be used for installation. Silicone or other solvent-based adhesives can damage the material structure or cause sagging over time.
Can the product be used directly without painting?
The product comes in white with a protective factory primer. However, for a seamless look and to hide the joint lines, we highly recommend painting it after installation. You can paint it with water-based or synthetic paints.
Will it deform or swell in humid areas?
No, thanks to its closed-cell structure, its water absorption rate is close to zero. Therefore, it can be safely used in bathrooms, kitchens, or other high-humidity interior spaces without swelling, cracking, or losing its shape.
