Standard Cement Coated Waterproof Backer Board
High-Performance Cementitious Substrate for Tile Systems & Wet Areas
Manufactured with a high-density cementitious core and an integrated waterproof surface barrier, this backer board delivers reliable, long-term structural support for ceramic, porcelain, and natural stone tiles. Engineered specifically for high-humidity environments and heavy-load assemblies, it eliminates the vulnerabilities of traditional gypsum drywall-preventing substrate softening, mold growth, tile cracking, and adhesive failure in demanding commercial and residential projects.
Technical Advantages & Performance
High-Density Cement Core
- Composition: Inorganic Portland cement combined with mineral aggregates and reinforcing mesh.
- Load Performance: Delivers high compressive and flexural strength, supporting heavy stone finishes without sagging or creeping under continuous loads.
- Moisture Resilience: Does not lose structural integrity, swell, or degrade when subjected to prolonged moisture exposure.
Integrated Waterproof Surface Coating
- Function: A factory-applied waterproof barrier sealed directly to the board surface minimizes water absorption.
- Application Impact: Stops moisture migration behind the tile assembly, protecting wood or metal framing in shower enclosures, commercial kitchens, and wet rooms.
Dimensional Stability
- Thermal & Moisture Movement: Low linear expansion and contraction coefficients under extreme temperature fluctuations and relative humidity shifts.
- Result: Minimizes shear stress transferred to the tile joints, significantly reducing surface cracking and grout line failure.
Superior Adhesive Bond Strength
- Surface Profile: Textured cement surface optimized for mechanical and chemical bonding with polymer-modified thin-set mortars (ANSI A118.4 / ANSI A118.15 compliant).
- Efficiency: Eliminates the need for extensive surface priming before tile installation.
Fire Resistance (Class A Non-Combustible)
- Inorganic Structure: Manufactured entirely from non-combustible mineral materials, slowing flame spread and maintaining barrier integrity under high heat exposure.

Physical Testing: Periodic breaking load and flexural strength testing per international building material standards.
Supply Chain & Logistics Support
Flexible MOQ: Scalable production schedules to support both trial orders and large-scale infrastructure projects.
Lead Time: Standard production completed within 15-25 days per container load.
Export Packaging: Moisture-proof plastic wrapping, heavy-duty edge protectors, and ISPM 15-compliant heat-treated wooden pallets designed for secure global ocean freight.
FAQ
Q: What is a cement coated waterproof backer board used for?
A: It is primarily used as a high-performance tile backing substrate in wet and high-moisture areas such as bathrooms, shower enclosures, commercial kitchens, and large-scale construction projects.
Q: Why choose a cement backer board instead of regular drywall?
A: Regular drywall easily absorbs moisture, leading to structural softening and mold growth in wet environments. Our cement backer board utilizes an inorganic cement-based core that guarantees superior moisture resistance, mold prevention, and robust load-bearing support for heavy tile installations.
Q: Can this board be used for shower walls?
A: Yes. These boards are specifically engineered for shower walls, steam rooms, and tub surrounds when installed with appropriate waterproofing and tile systems.
Q: Can it be used for floor applications?
A: Yes, depending on the specified thickness, structural load requirements, and project design. We recommend matching the board specification to your precise tile format and traffic load conditions.
Q: What thickness options are available?
A: Standard production thicknesses include 6mm, 8mm, 10mm, and 12mm, with bespoke thicknesses available upon custom order request.
Q: Do you support OEM packaging for global distributors?
A: Yes. We offer comprehensive private-label solutions, including custom carton labeling, pallet designs, logo stamping, and export-compliant packaging.
