For exterior wall renovation, 21Parkhouse® Flexible Stone is emerging as the preferred new material, thanks to its unique advantages.

For instance, a large industrial park in Guangzhou Huadu district experienced issues where weathering and water stains appeared on the exterior walls, partly due to high construction dust. Furthermore, the original building's coating layer lacked a reinforcing mesh, which led to large square cracking. The necessary remedial work includes removing the old material, re-leveling, waterproofing, and mesh installation.

Before innovation:

Using traditional materials necessitates the demolition of the original coating layer. Scaffolding protection is required to mitigate dust dispersion and the risk of material spalling.

However, the combination of flexible stone and swing stage construction effectively addresses the issues inherent in traditional methods. Flexible stone optimizes the efficiency of vertical transport and construction, minimizing the engineering time; swing stage has less impact on the building, no need for large-scale scaffolding. This approach provides an ideal solution for the difficulty in high-rise exterior wall renovation while minimizing the disruption to the surrounding environment and occupants' daily life.

Under renovation:

To deal with weathered traces and water residue marks, flexible stone is factory-prefabricated with Curved drip edge with integral molding. To align with our brand, we specially design a petal-shape component, making rain discharge outward away from the wall surface. The curved slope accelerates drainage, creating a scouring effect and reducing stain deposition. The lower arch design helps prevent sewage backflow, maintaining the building's appearance as clean as new.

The unique flexibility of flexible stone allows it to curve seamlessly with the drip edge, creating a unified, continuous, and cohesive appearance.

After innovation:

Flexible stone restores the texture of natural stone and offers brilliant weather resistance and stain resistance. Mold-resistant and crack-resistant, with a clean and white finish, improving the visual sophistication and receiving unanimous praise from owners.

*After three months of testing, we can clearly see that under the impact of rain and dust, the surface of traditional coating appears obvious weathered traces. By contrast, flexible stone has less staining, and its stain resistance is close to aluminum plate, maintaining llong-term clean and attractive.

In the wave of continuous innovation in modern construction technology, the optimization of materials and construction methods is equally crucial. Recently, the 21Parkhouse® brand was invited to participate in the Hong Kong seminar, "Smart Construction in the Greater Bay Area: Assurance Renovation, Building Upgrade and Sustainable Development," where it delivered an engaging presentation titled "New Building and Exterior Wall Renovation Environmental Technology Finishing."

The seminar also included the sharing of multiple real-world application cases. These cases fully demonstrate that in practical use, 21Parkhouse® Flexible Stone (Soft Stone) not only successfully addresses the numerous pain points faced by traditional renovation methods but also brings lasting aesthetic appeal and superior performance to buildings.

Case 1: Seminyak Star Shopping Center, Bali

*21Parkhouse® Bricks were chosen for the interior walls, exterior walls, and ceiling. They were directly applied onto the original cement and old aluminum panel substrates, covering an area of 3,000 m², with project completion in approximately two weeks.

Case 2: Guangzhou South Tower International Electronic Digital City

*During the Guangzhou Asian Games, the Guangzhou Municipal Government selected 21Parkhouse® Travertine, a material made from eco-friendly raw materials that generates no solid waste, for the large-scale renovation of the city's exterior façades. Sixteen years after completion, the project still maintains a 90% newness rate.

Case 3: Guiyang Heshe Hotel

*21Parkhouse® Bricks were chosen for the exterior wall renovation, applied directly onto the original mosaic substrate. The usage area reached 20,000 m². The product offers self-cleaning, stain-resistant, and anti-aging properties, and the project has been standing for 11 years since completion.

Case 4: Tak Shing House, Hong Kong

*300㎡ of the exterior wall utilized 21Parkhouse® Evian Stone.

Case 5: 75 Fuk Lo Tsun Road (Wang Jing Project), Hong Kong

*400㎡ of the exterior wall utilized 21Parkhouse® Tours Line Stone and Evian Stone.

· Exceptional Durability and Aesthetic Appeal

Flexible Stone closely mimics the texture of natural stone and wood grain with high fidelity. Its durability is at least 5 times that of traditional coatings, offering an exterior wall lifespan of 30–50 years, far exceeding the 5–10 year warranty period of conventional paints. This effectively avoids issues like discoloration, yellowing, cracking, and peeling, significantly lowering future maintenance costs.

· Efficient and Convenient Installation

Flexible Stone Slab is thin, lightweight, and pliable, allowing it to be applied directly over various existing finishes. Installation is fast and simple; general workers can execute the process after training from the manufacturer, greatly reducing the construction period and minimizing disruption to the daily lives of occupants.

· Significant Cost Advantage

Flexible Stone Slab achieves visual effects comparable to stone, wood, and woven materials, but its comprehensive cost is only one-third that of natural stone. It also offers advantages in transportation and installation, truly achieving both cost reduction and increased efficiency.

· Superior Environmental Performance and Functionality

As an eco-friendly material, Flexible Stone Slab offers excellent performance in fire resistance, mold resistance, water resistance, and resistance to acid-alkali corrosion. This allows it to effectively cope with challenges such as the humid climate in Hong Kong and the acid rain in the Pearl River Delta region.

Facing the growing demand for urban renewal, we sincerely advocate for placing construction safety at the forefront of all considerations. 21Parkhouse® will continue to uphold its brand mission of "Safety, Sustainability, and Innovation," working hand-in-hand with industry partners to promote smarter and safer construction methods, and jointly empower the building industry with superior products to usher in a new, safer, and better construction era.
