Matching polyurethane door surround components for the KKAP29 decorative casing set
Create a grand entrance with the KKAP29 door surround kit. This coordinated set includes P1470A and P2833 pediments, P1470 and P1458 casings, plus P9950 and P9927 decorative corbels. All premium PU parts fit seamlessly for a flawless, paint-ready finish.












The KKAP29 door surround set is a grand-scale architectural portal designed to transform standard entryways into majestic, high-profile focal points. Engineered for both exterior facades and prestigious interior spaces, this combined framing set brings classical symmetry and deep architectural relief to upscale residential and commercial buildings. Whether welcoming guests to a private estate or a luxury boutique hotel, this structural-style frame establishes an immediate sense of scale and architectural integrity.
Manufactured from high-density rigid polyurethane (150-220 kg/m³), the components offer the solid feel of traditional timber or stone without the associated weight or vulnerability. Measuring 2080 mm in width, 2630 mm in height, and featuring a prominent depth of 257 mm, the set is surprisingly lightweight, making installation safe and efficient. Its closed-cell structure ensures water absorption remains under 1%, preventing rot, swelling, or cracking under extreme weather. With dimensional stability tested between -20 °C and +70 °C, it maintains exceptional dimensional stability through seasonal cycles.
Visually, the KKAP29 set is defined by its ornate arched pediment featuring elaborate floral and scrollwork reliefs. This crowning element is supported by twin side pilasters embellished with highly detailed capitals that showcase classical mask motifs, fluted columns, and acanthus leaf brackets. The deep-set profiles capture natural light beautifully, casting sharp, dramatic shadows that highlight the craftsmanship. This level of fine detail is virtually impossible to achieve with EPS foam and far more durable than fragile gypsum plaster.
This entrance portal is exceptionally versatile, adapting to neoclassical, Mediterranean, or Georgian architectural styles. It is ideally suited for main villa entrance doors, luxury restaurant foyers, and historical facade restorations. The set comes with a factory-applied primer that prepares the surface for painting. While this base layer facilitates paint adhesion, applying an additional primer coat is optional and depends on the specific warranty guidelines of your chosen paint brand.
For secure installation, ensure the mounting surface is clean and dry. Apply polyurethane (PU) assembly adhesive along the contact edges, position the pieces, and secure them mechanically with screws. After filling the joint lines and screw holes with an exterior-grade filler, sand the surface smoothly before applying two coats of high-quality, UV-resistant paint to protect the material from sun exposure.
- This grand entrance set is primarily designed for framing high-end exterior entryways, such as the main front doors of luxury villas, estates, and upscale residential complexes
- It is also highly effective in commercial settings, including the portals of boutique hotels, prestigious restaurants, and executive offices where a strong first impression is essential
- Beyond exterior facades, the set can be integrated into spacious interior designs, such as grand ballroom entrances, transition arches in expansive residential halls, or classical library doorways
- For the best visual impact, pair this light-toned frame with dark wood or bronze double doors to create a striking, high-contrast architectural statement
- Begin by preparing a clean, dry, and level mounting surface
- Carefully measure and align the pilasters and the arched pediment
- Apply a generous amount of polyurethane (PU) assembly adhesive to the rear bonding surfaces of each component
- Press the parts firmly onto the wall and secure them mechanically using screws to ensure structural stability
- Once the adhesive has cured, fill all joint seams and screw heads with a high-quality exterior-grade joint filler
- Gently sand the patched areas using 180-220 grit sandpaper to achieve a seamless, uniform surface
- Finally, apply a premium UV-resistant paint
- While the factory primer provides an excellent base, an optional additional primer coat can be applied based on your paint manufacturer's recommendation
- The high-density material requires minimal maintenance
- For exterior applications, the frame can be gently washed with water or wiped down with a damp cloth to remove environmental dust and dirt
- We recommend inspecting the paint coating once a year to ensure the UV protection remains intact
- In the event of accidental impact or surface scratching, the damaged area can be easily repaired by applying exterior putty, sanding it smooth, and touch-up painting, restoring the portal to its original pristine state
Can the KKAP29 entrance set withstand harsh outdoor weather?
Yes, the KKAP29 is highly weather-resistant. Made from closed-cell rigid material with under 1% water absorption, it will not rot, warp, or crack when exposed to rain, snow, or humidity. It remains stable in temperatures ranging from -20 °C / +70 °C. However, applying a UV-resistant exterior paint is mandatory to protect it from sun damage and yellowing.
Is it necessary to use screws during the installation of this large portal?
Yes, due to its grand dimensions (2080x2630 mm) and 257 mm depth, mechanical fastening with screws is mandatory alongside the use of polyurethane (PU) assembly adhesive. This dual-fastening method ensures the heavy-profile components remain permanently and safely secured to the facade.
Does the product require an extra primer before painting?
The set is delivered with a factory-applied primer that prepares the surface for paint. While you can apply quality exterior paint over this base, paint manufacturers often require their own primer for their warranty to be valid. Therefore, applying an additional primer is optional and left to the installer's discretion.
How does this material compare to traditional gypsum plaster or stone?
Unlike heavy stone or fragile gypsum, this high-density material (150-220 kg/m³) is lightweight, making transport and installation safer and faster. Assess water and moisture exposure using the product technical data, surface finish and installation details.
Can the dimensions of the KKAP29 set be customized or adjusted?
The set consists of modular pilasters and a central pediment. While the pediment has fixed dimensions, the height of the entrance can be adjusted during installation by cutting the vertical pilaster shafts at the base before securing them, allowing it to fit various door heights.
