Frequently Asked Questions

MCM Flexible Stone (short for Modified Clay Material) is a thin, bendable stone veneer made from natural mineral powder and polymer. It looks and feels like real stone, but it's only 2.5 to 4mm thick and weighs about 4.2 to 8.6 kg per square meter — roughly one-fifth the weight of traditional ceramic tiles.

Think of it this way: if you took a solid stone slab and made it thin enough to bend around a column, you'd get something close to MCM flexible stone. It can wrap around curves with a radius as small as 20cm, which means you can use it on cylindrical pillars, domed ceilings, and arched doorways — places where regular tiles simply can't go.

Unlike printed surface tiles that just have a stone pattern on top, MCM flexible stone uses a through-body coloring process. The color runs all the way through the material, so even if you scratch the surface, the same color shows underneath. This also makes it far more UV-resistant — the color won't wash out after a few years in the sun.

Fortune Stone (officially Guangdong Xinrunshi New Materials Co., Ltd.) is a manufacturer specializing in MCM flexible stone veneer. Our factory is located in Boluo County, Huizhou, Guangdong Province, China. We design, produce, and ship flexible stone products for both domestic and international projects.

Our product line includes 90+ designs across three collections, covering everything from everyday limestone and brick textures to high-end travertine and custom artistic finishes. We serve hotel renovations, residential exteriors, commercial buildings, and government infrastructure projects.

One of our flagship projects is the Melbourne Olympic Village renovation in Australia, where our flexible stone was used in a pre-fabricated panel system for exterior cladding. Domestically, we completed a 200-room hotel renovation in Huizhou in just 20 days using our direct-to-old-wall installation method.

Fortune Stone brand identity — the logo combines a flower bud shape with the letters F and S, representing natural beauty meets architectural innovation.

Our manufacturing facility is in Boluo County, Luoyang Subdistrict, Huizhou City, Guangdong Province, China (postal code 516199). This is our new production base, which we moved into as part of our expansion plan. The location gives us access to the Greater Bay Area logistics network, so we can ship to Shenzhen port and Guangzhou port within a few hours.

The factory handles the full production cycle: raw material mixing, molding, coloring, sintering, cutting, and packaging. Below are photos from inside our facility, showing the production floor and warehousing area.

When you place an order, your products are packed, crated, and loaded directly from this facility. Here's what the shipping process looks like:

We have 90+ designs organized into three collections, each designed for different use cases and design goals:

• Star Collection (30 designs): Our best-sellers — limestone, granite-texture, slate, wood grain, red brick, and blue brick. These are the workhorses for hotel renovations, residential exteriors, and commercial facades. Thickness: 2.5–2.8mm (standard) or 3–4mm (textured types like granite and wood grain). Weight: 4.2–5.6 kg/m².
• Travertine Gallery (30 designs): Premium designs that replicate natural travertine stone, including Roman travertine,侘寂 (wabi-sabi) white, and gradient finishes. These are the ones architects specify for hotel lobbies, sales centers, and high-end villas. All designs are 2.5–2.8mm thick, 4.2 kg/m².
• Texture Encyclopedia (30 designs): Our most creative line — sandstone, volcanic rock, mosaic, woven hemp, rammed earth, charred wood, and more. These range from 2.5mm to 11mm thick depending on the design, and are popular with designers working on art spaces, feature walls, and curved architectural elements.

Available sizes include 600×1200mm, 1200×2400mm, and 1200×3000mm. We can also accommodate custom sizes for large projects.

Our showroom displays different finishes side by side, so you can compare textures and colors in person.

Yes, absolutely. MCM flexible stone is designed for both interior and exterior use, and this is one of the most common questions we get from buyers.

The key reason it works outdoors is the through-body coloring process. Unlike printed tiles where the color is only on the surface, our flexible stone has color running all the way through the material thickness. This means UV rays can't "burn off" the color the way they would with a surface print.

We tested this in the lab with 4,000 hours of xenon lamp UV aging (which simulates years of outdoor sun exposure). The color difference measured ΔE ≤ 1.5 — that's a change so small it's not visible to the naked eye. We also passed 50 freeze-thaw cycles, which means the material can handle cold climates where winter temperatures drop below freezing.

We have real-world projects in Hainan (tropical, high UV, high humidity) and Northeast China (sub-zero winters, large temperature swings) that have been standing for years without visible fading or deterioration.

One important note: All Fortune Stone products use the through-body coloring process. Some cheaper flexible stone on the market uses surface printing instead — those products will fade in 2–3 years outdoors. Always confirm you're getting through-body colored material for exterior projects.

This is a question every serious B2B buyer should ask. Here's what we hold:

• ISO 14001:2015 Environmental Management System — certified by ZOZEN International, covering our production and sales operations. Valid through March 2029.
• Fire Rating: B1 (standard) and A2 (modified version) — tested per GB 8624-2012, the Chinese national standard for building material fire performance. The material does not produce burning drips and has low smoke toxicity.
• SGS Environmental Safety — formaldehyde emission: not detected (<0.1mg/m³). Benzene, toluene, and xylene: not detected. Radioactivity meets Class A decorative material standard (safe for interior use including bedrooms and hospitals).
• 4,000-hour Xenon Lamp UV Aging Test — color difference ΔE ≤ 1.5.
• 50 Freeze-Thaw Cycle Test — passed, suitable for cold-climate exterior use.
• 1,500-hour Artificial Climate Aging Test — passed, demonstrating long-term weather resistance.

ISO 14001:2015 Environmental Management System Certification — issued March 2026, valid through March 2029.

We can provide copies of test reports and certificates upon request. For specific project requirements (like EU CE certification or particular fire standards), please contact our team and we'll send the relevant documentation.

Installation is done using a wet-paste method — similar to how you'd install regular wall tiles, but simpler because the material is lighter and more flexible. Here's the basic process:

1. Check and prepare the wall surface (clean, repair cracks)
2. Apply bonding agent / primer to the wall
3. Mix our GR91专用粘结剂 (dedicated adhesive) — do not substitute with regular tile adhesive
4. Use a notched trowel to spread adhesive on both the wall and the back of the flexible stone
5. Press the stone onto the wall using a rubber pressure plate (do not use a metal hammer)
6. Grout the joints (typically 2–4mm gap)
7. Keep the surface protected from rain and foot traffic for 24 hours

For a 3,000m² exterior project, the typical timeline is about 20–30 days — roughly half the time of traditional stone cladding (60–90 days) or real stone paint (45–60 days).

Yes, it can go on curved walls. MCM flexible stone can bend around curves with a radius of 20cm or more. This means you can wrap it around cylindrical columns, domed ceilings, archways, and rounded corners — places where rigid tiles would need to be cut into small pieces.

As for tools, you mainly need a notched trowel, electric mixer, rubber pressure plate, level, and a cutting tool. We also offer a patented dust-free cutting machine that captures dust during cutting, making it suitable for indoor renovation projects where dust control matters.

Yes — and this is one of our biggest advantages. If your existing wall has old ceramic tiles, old paint (as long as it's not peeling off in sheets), or old cement render, you can install MCM flexible stone directly on top without demolishing the old surface.

Here's what makes this possible: our material is so light (under 6 kg/m² for most products) that the existing wall structure doesn't need extra reinforcement. You just need to:

• Clean the surface — remove loose dust and debris
• Tap with a hollow-sounding hammer to check for loose tiles (if more than 5% of an area sounds hollow, repair those spots first)
• Apply bonding agent / primer
• Install the flexible stone directly

This saves an enormous amount of time and money. In our Huizhou 200-room hotel project, the old wall tiles were left in place. The renovation was completed in 20 days instead of the originally planned 45 days, because there was no demolition phase.

One caution: If the old paint is heavily chalked or powdery (you can rub it off with your hand), you do need to scrape it down to a solid layer first. The rule is simple — the base must be solid enough to hold weight. When in doubt, do a pull-off adhesion test.

Our standard MCM flexible stone has a fire rating of B1 (difficult to ignite) under the Chinese national standard GB 8624-2012. We also offer a modified version that achieves A2 (non-combustible) for projects with stricter fire requirements.

What does that mean in practice?

• B1 rated: The material will not easily catch fire. If exposed to flame, it self-extinguishes when the flame is removed. It does not produce burning drips (molten material falling and spreading fire), and smoke toxicity is low.
• A2 rated: Even harder to ignite. This is the rating typically required for high-rise building exteriors, public spaces, and projects where building codes demand non-combustible cladding.

For high-rise and public building projects, we recommend specifying the A2-rated version. We can provide the fire test report for your specific product batch — the report number will match the material you receive, not a generic sample.

Additionally, because MCM flexible stone is lightweight (under 6 kg/m² for standard products), it doesn't add significant load to building structures. This is a major advantage over traditional stone cladding (30–40 kg/m² plus steel anchoring systems), especially for high-rise buildings where weight and wind load are critical design factors.

MCM flexible stone is made primarily from inorganic mineral materials — natural stone powder and mineral-based binders. No organic glues or solvents are added during production. This is fundamentally different from many decorative materials that rely on resin-based adhesives.

We had SGS (one of the world's leading testing companies) run a full environmental safety test. Here are the results:

• Formaldehyde emission: Not detected (<0.1 mg/m³)
• Benzene, toluene, xylene combined: Not detected
• Radioactivity: Meets Class A decorative material standard (the strictest category in China — safe for interior use including bedrooms, kindergartens, and hospitals)

We also hold ISO 14001:2015 Environmental Management System Certification, which means our manufacturing process itself meets international environmental standards — not just the final product.

For buyers sourcing materials for green building projects (LEED, BREEAM, China Green Building Label), our material can contribute to credits in the low-emitting materials and recycled content categories. Contact us for specific documentation.

ISO 14001:2015 certification — covers both product and manufacturing process environmental management.

Based on third-party laboratory testing (accelerated aging data from the National Building Materials Testing Center), the design service life of Fortune Stone MCM flexible stone is 10 to 15 years under normal weather conditions. Our earliest installed projects have now been in place for over 8 years with no visible deterioration.

For comparison, here's how that stacks up against common alternatives:

• Real stone paint (真石漆): Typically 5–8 years before needing repainting or repair
• MCM flexible stone: 10–15 years (lab data, verified by real-world projects)
• Traditional dry-hung stone: 20+ years, but at 3–5x the cost

We back our products with a 10 to 15-year manufacturer warranty (exact term specified in contract). The warranty covers product quality issues such as fading, cracking, or delamination caused by material defects — not by installation errors or external damage.

If you encounter any issues after installation, our customer service team responds within 24 hours and provides an initial solution within 48 hours. For on-site inspections, we coordinate with local representatives or send a technician within 3–7 business days, depending on location.

Getting samples is simple. We offer two options:

• Individual samples: Order specific designs to see the texture and color in person. Individual samples cost about 25–75 RMB per piece depending on the design series.
• Full sample display kit (GR92): Includes 3 display racks with all 90+ designs. Priced at 3,000 RMB per set. If your cumulative orders reach 30,000 RMB, the full sample kit cost is refunded.
