The P5260D50 is a semi-circular architectural element specifically designed for 50 cm diameter circular load-bearing or decorative column systems. Serving as both a column capital and a column base, this versatile piece helps you create elegant classical and neoclassical transitions in your interior and exterior projects. It provides a balanced visual harmony in building entrances, facade designs, or interior column claddings.
Manufactured from high-density (150-220 kg/m³) rigid polyurethane, this product features ideal proportions for large-scale projects, measuring 420 mm in width, 840 mm in length, and 380 mm in height. Thanks to its closed-cell structure, its water absorption rate is below 1%, preventing rotting, swelling, or molding even in highly humid environments. It maintains its dimensional stability and shape in temperatures ranging from -20 °C / +70 °C.
The design highlights a simple yet powerful profile where circular lines merge with gradual transitions. Its smooth, stepped circular structure offers a modern interpretation of classical Doric or Tuscan architectural orders. The high surface clarity achieved through advanced molding technology combines the flawless look of traditional hand-carved stonework with effortless installation.
It boasts a wide range of applications, being highly favored for villa facades, hotel entrances, wedding venues, and restaurant decors. Indoors, it creates an aesthetic column accent when applied as half-columns against walls in spacious living rooms, lobbies, and hallways. It is also an excellent option for elegantly cladding existing steel or reinforced concrete pipe columns.
Compared to plaster alternatives, it is extremely lightweight and adds no static load to the building; unlike EPS foam products, it offers far superior impact resistance. The product is shipped with a factory-applied protective primer. While this primer prepares the surface for painting, applying an additional coat of primer is entirely optional and depends on the customer's preference, often subject to the warranty terms of specific paint brands. For outdoor installations, painting with UV-resistant paint is mandatory to prevent yellowing.
During installation, Polure Polfix adhesive should be applied to a clean, dry surface, followed by mechanical fastening with screws. Once the screw holes and joints are filled with putty and smoothed using 180-220 grit sandpaper, a flawless finish is achieved by applying two coats of paint.
- The P5260D50 half column capital and base offers a wide range of applications, from cladding load-bearing columns to creating decorative half-columns on wall surfaces
- Externally, it is ideal for creating a grand welcoming entrance on luxury villa facades, palace-style residential exteriors, and on both sides of hotel and restaurant entrance doors
- Internally, it is used to clad rough reinforced concrete or steel pipe columns in the middle of large halls, transforming them into aesthetic architectural columns
- It can also be adhered to wall surfaces in lobbies, entryways, corridors, or bedrooms to create a half-column decor
- For outdoor applications, painting with a UV-resistant facade paint post-installation ensures long-lasting protection against harsh weather conditions
- In restoration projects, architects frequently prefer it to replicate the look of historic stone columns without adding significant extra weight, thanks to its lightweight advantage
- The application surface must be completely free of dust, moisture, and dirt
- Apply high-bonding Polure Polfix adhesive to the back of the product and position it on the mounting surface
- Since this is a large and substantial element, adhesive alone is not sufficient; mechanical fastening with dowels and screws is mandatory
- Screw heads should be slightly countersunk into the surface
- Following installation, fill the screw holes and joints with a high-quality exterior putty
- Once dry, sand the puttied areas with 180-220 grit sandpaper until smooth
- An optional additional coat of primer can be applied over the factory-primed surface according to the paint manufacturer's recommendations
- In the final step, complete the process by applying at least two coats of water-based paint for interiors or UV-protected exterior paint for outdoor applications
- Thanks to its closed-cell structure, the polyurethane column capital is moisture-resistant, making maintenance exceptionally easy
- For indoor use, accumulated dust can be wiped periodically with a damp cloth
- For outdoor installations, surface dirt and dust can be washed away with pressurized water
- Avoid using abrasive acids, thinners, or harsh chemical solvents during cleaning
- For exterior applications, the painted surface should be inspected every few years depending on sun exposure and weather conditions, and a protective coat of paint should be reapplied if necessary
- With these simple care steps, the product will retain its shape and durability for a long time with proper paint and maintenance
Is the P5260D50 product suitable for outdoor use?
Yes, the product is fully suitable for outdoor use. Thanks to its rigid polyurethane structure, it is resistant to weather conditions such as rain, snow, frost, and moisture, and it is highly resistant to rot. However, to protect it from the sun's UV rays, it must be painted with a high-quality UV-resistant exterior paint after installation.
Which adhesive should be used during installation, and are screws mandatory?
Only Polure Polfix polyurethane adhesive should be used for installation; standard silicones may lose their strength over time. Additionally, due to the size and safety of the product, mechanical fastening with screws is strictly mandatory. Screw heads can be concealed with putty to achieve a seamless look.
Can the product be used directly without being painted?
The product is shipped with a factory-applied white primer. However, to protect the material from external elements and ensure aesthetic harmony, it is highly recommended to paint it before use. Unpainted polyurethane surfaces, especially outdoors, may yellow over time.
What are its advantages compared to plaster or concrete column capitals?
While plaster columns are very heavy and carry a risk of cracking or breaking, concrete elements add significant static load to the building. In contrast, this product is extremely lightweight yet impact-resistant, quick to install, and will not crack or crumble over time.
Is it necessary to apply primer again before painting?
The factory primer on the product prepares the surface for painting. However, paint brands may not offer a warranty for applications done without their own primers. Therefore, applying an additional coat of primer is optional and entirely up to the installer.
