The STS Fibre Cement Construction Board is designed for professional contractors and serious DIY enthusiasts who need a reliable, high-performance substrate for wet rooms, floors, and wall installations. Offering superior moisture resistance and structural rigidity, this 12mm board ensures a stable, long-lasting foundation for tiling and decorative finishes. While its high-density composition provides exceptional durability, users should note that the board is heavier than standard gypsum alternatives, requiring careful handling during installation.

Yes, their moisture and impact resistance make them suitable for outdoor applications, provided they are installed according to exterior cladding best practices.
A high-quality flexible tile adhesive is recommended to accommodate the properties of the cement board substrate.
While the surface is ready for tiling, applying a standard acrylic primer can help manage suction and improve adhesive bond strength.
The product is supplied in a convenient 6-pack.
Yes, the smooth finish allows for direct painting, though a suitable primer should be applied first for the best results.
The material is non-combustible, offering excellent fire-resistant properties compared to timber-based boards.
Use a specialized circular saw blade for fibre cement and ensure the board is fully supported along the cutting line.
Ensure you are using screws rated for cement board with countersink heads and pre-drill pilot holes if necessary.
Utilize a dust extraction attachment on your power tools and wear an N95 or P2-rated respirator mask.
Installation requires standard structural fasteners appropriate for your frame type (wood or metal). Always ensure the boards are fixed at regular intervals to maintain structural integrity. For cutting, use a tungsten carbide-tipped blade to manage the dense fibre-cement material effectively. To minimize dust, consider using a vacuum extraction system or working in a well-ventilated area. While the boards are moisture-resistant, always ensure joints are sealed with a professional-grade waterproof tape or sealant when installing in wet rooms to create a fully tanked environment.
