The P5250D50 half column capital is an architectural polyurethane element designed to elegantly complement column designs in both interior and exterior spaces. Perfect for wall-mounted semi-circular column projects, this piece provides a seamless transition from the shaft to the ceiling or beam, infusing spaces with a classic character. Inspired by the clean, strong lines of the Doric order, its design is ideal for architects seeking understated elegance in both modern and classical projects.
The product measures 350 mm in depth, 700 mm in width, and 315 mm in height. It is manufactured from high-density rigid polyurethane (150-220 kg/m³). Thanks to its closed-cell structure, its water absorption rate is below one percent, offering strong resistance to moisture, rain, and outdoor weather conditions. With dimensional stability tested between -20 °C and +70 °C, it does not crack, shrink, or expand.
Visually, the design features a wide flat band at the top and a smooth, outwardly curving circular profile in the middle. These clean geometric lines create a balanced, visually pleasing aesthetic. The hollowed-out back ensures a perfect fit onto semi-column shafts. The product is shipped with a factory-applied primer, preparing the surface for the final coat. However, as paint manufacturers often recommend their own primers, applying an additional primer coat is entirely at the user's discretion. Polure does not warrant post-applied paints.
Its applications are highly versatile. It is widely preferred in villa facade decorations, luxury hotel entrances, wedding venues, restaurants, and retail window displays. It is also an excellent choice for creating decorative focal points on the walls of high-ceilinged indoor halls. Include the product weight and fixing loads when assessing the substrate and supporting structure.
During installation, Polure Polfix adhesive should be applied to the cleaned surface, followed by mechanical fastening with screws. Once screw holes and joints are filled with putty and sanded smooth, the painting process can begin. For exterior applications, the use of UV-resistant paint is mandatory to prevent the material from yellowing under UV rays.
- The P5250D50 polyurethane half column capital is highly versatile, suitable for both interior designs and exterior architecture
- Outdoors, it serves as an elegant transition element around villa entrance doors, at the top of decorative facade columns, and on spacious balcony or terrace supports
- Indoors, it creates a sense of depth in hotel lobbies, large restaurant halls, and prestigious office entrances when paired with wall-mounted semi-column shafts
- Thanks to the smooth, geometric nature of the Doric style, it can be used as a complementary detail alongside wall paneling and door casings in minimalist, neoclassical, or modern decor projects
- When finished with appropriate exterior paint, it becomes highly resistant to outdoor weather conditions
- Installation should be carried out on a clean, dry surface
- First, apply Polure Polfix adhesive to the rear mounting surface and position the product on the wall
- Unlike heavy architectural elements, its lightweight nature makes it easy to handle, but mechanical fastening with wall plugs and screws is mandatory for a secure installation
- Screw heads and joints should be filled with high-quality exterior putty
- Once the putty dries, sand the surface smooth using 180-220 grit sandpaper
- An optional extra coat of primer can be applied over the factory primer in accordance with paint manufacturers' recommendations
- In the final step, apply at least two coats of paint—using water-based or synthetic paints for interiors, and UV-resistant exterior paints for outdoor applications
- Thanks to its closed-cell structure, the polyurethane column capital is highly resistant to water and moisture, offering strong resistance to rot, swelling, and mold
- Cleaning is highly practical; it can be easily wiped down with a damp cloth or sprayed with low-pressure water outdoors
- Unlike wood, it does not require periodic maintenance against insect infestation or decay
- For exterior use, it is recommended to inspect the UV paint layer annually and touch it up if necessary to extend the lifespan of the paint
Can the polyurethane half column capital be used outdoors?
Yes, the product is highly resistant to water, moisture, and harsh weather conditions, making it safe for exterior use. However, since unpainted polyurethane can yellow under sunlight, it must be coated with UV-resistant exterior paint for outdoor applications.
Which adhesive should be used during installation?
Only Polure Polfix adhesive should be used for installation; silicone-based adhesives are not recommended. Additionally, for long-lasting stability and safety, mechanical fastening with screws and wall plugs is required.
Can the product be used directly without painting?
The product comes with a factory-applied white primer. However, it should be painted to protect the surface and ensure aesthetic consistency. While the factory primer prepares the surface for the topcoat, applying an additional primer is entirely up to the user for paint warranty purposes.
What are its advantages compared to plaster column capitals?
Compared to plaster, it is extremely lightweight, meaning it adds no static load to buildings and carries a low risk of breakage during transport. Additionally, its water-resistant nature prevents cracking and flaking outdoors, and installation is significantly faster.
Which column sizes are compatible with the P5250D50 half column capital?
The product has a width (diameter opening) of 700 mm and a depth of 350 mm. Accordingly, it perfectly matches semi-circular column shafts with a 70 cm outer diameter or flat wall surfaces of corresponding dimensions.
