  • 1. What are the raw materials of 21Parkhouse Flexible Stone?

    The primary components are stone powder, clay, and other natural inorganic substances. These materials are pressed at low temperatures, making the production process low-carbon and environmentally friendly. 21Parkhouse has received environmental certifications such as the China Green Label, UL in the United States, and the Singapore Green Label.

  • 2. Is 21Parkhouse Flexible Stone the same as Soft Ceramics/Soft Stone/Flexible Stone? What are the differences?

    Soft ceramics typically only offer monochromatic effects, whereas Flexible Stone can achieve 3D coatings, resulting in more varied and richer patterns.

     

    Many so-called "soft ceramics/soft stone/flexible stone" products on the market include 40-60% chemical adhesives to achieve a "soft" effect, which can cause shrinkage and detachment after installation. Flexible Stone uses less than 10% of an environmentally friendly modifier (Patent No.: ZL200910226004.0) to ensure flexibility and durability.

     

    Soft ceramics/soft stone/flexible stone are usually available in smaller sizes such as 1200600mm or 600300mm, while Econic Clay comes in larger formats like 24001200mm or 27001200mm.

  • 3. What are the advantages/differences between 21Parkhouse Flexible Stone and other manufacturers?

    Invention Patent Technology
    With an invention patent for the core soft porcelain technology “Eco-Active Clay,” we are the drafting unit of the national industry standard for soft porcelain in China. After the standard was released in 2014, the market gradually saw the emergence of other soft porcelain/soft stone/flexible stone brands.

    Production Process & Capacity Advantage
    While traditional soft porcelain/soft stone/flexible stone products in the market are still based on the first or second generation of production technology, flexible stone is undergoing an upgrade from the fourth to the fifth generation of production processes.

    3D Surface Coating Technology
    Due to technical limitations, traditional soft porcelain/soft stone products in the market mainly feature solid colors with limited design variety. In contrast, flexible stone uses fifth-generation 3D surface coating technology to authentically replicate the textures of natural stone, wood, and woven materials. Patterns and designs can be customized based on demand, offering a much richer range of aesthetic options.

    Raw Materials
    Lacking core patented technology, traditional soft porcelain products on the market often contain a high proportion of adhesives to reduce costs. This compromises breathability, leading to issues such as hollowing and detachment. Flexible stone, on the other hand, uses the patented “Eco-Active Clay” technology to refine natural inorganic materials at the micro level. This results in a breathable internal structure, making the product more durable, breathable, and resistant to hollowing and detachment.

    Fire Resistance Rating
    Due to technological limitations, most traditional soft porcelain/soft stone/flexible stone products on the market can only achieve a Class B fire resistance rating. In contrast, all flexible stone products meet Class A fire resistance standards.

     

  • 4. What should be noted when using flexible stone?

    Color Variation Across Batches
    Similar to natural stone, flexible stone may exhibit natural color variations between different production batches. This is due to the use of natural raw materials such as stone powder, clay, and quartz sand, which may vary slightly depending on the region of origin. Even after being pressed under a controlled temperature curve of 200°C, slight color differences (typically within 1–3 degrees) may still occur. This is considered within normal standards. (Note: There is no color difference within the same batch.) Therefore, it is recommended to install materials from different batches in separate areas to avoid noticeable color discrepancies on the same wall.

    Not Recommended for Seamless Installation
    Flexible stone is a "breathable material" with a water absorption rate of around 10%, similar to ceramic products. It may exhibit slight thermal expansion and contraction. For this reason, seamless installation (butt-jointing) is not recommended. A 2mm blade joint (natural seam) or color-matched grouting is advised, which maintains visual appeal while enhancing durability.

    Application Scope
    As a breathable material, flexible stone is suitable for interior and exterior wall surfaces and ceilings. It is not recommended for flooring applications. A version designed specifically for floor use will be launched in the future.

  • 5. What do "texture" and "pattern" mean?

    Texture refers to the three-dimensional surface feel of a product — the tactile quality you can touch. It includes surface types such as embossed, linear, woven, and wood grain textures, representing the physical depth and touchable detail of the material.

     

    Pattern refers to the color or flat surface design visible on the product — such as natural stone veining, wood grain visuals, or printed motifs. It represents the visual aesthetics of the material.

     

  • 6. Can flexible stone be customized in patterns or designs?

    Yes, pattern customization is available for flexible stone. The minimum order quantity (MOQ) for custom patterns is 150㎡. If the order does not meet the MOQ, an additional customization fee will apply.

  • 7. Can flexible stone be customized in texture?

    Yes, texture customization is available. We can create molds based on physical samples you provide, such as carved products, cultured stone, or wood grain samples. If no physical sample is available, you may also provide a grayscale image or a 3D model file for mold carving and replication.

  • 8. Can flexible stone be repainted after installation on the wall?

    Yes, it can. After installation, flexible stone can be repainted using water-based paint to change its color.

  • 9. What types of textures can flexible stone achieve?

    Flexible stone can replicate a variety of textures such as natural stone, wood grain, and woven patterns. The surface patterns and colors can also be customized to meet different design requirements.
