Fiber cement board impact resistance is an important consideration in walls, façades, modular buildings, corridors, schools, and other high-traffic areas. Fiber cement boards are durable and practical building boards. They are often selected for dry construction, external sheathing, façade backing, wet areas, and fire-safe wall systems.
A wavy or uneven fiber cement board wall is usually caused by poor frame alignment, incorrect support spacing, bad fixing, or weak substrate preparation. Fiber cement boards can create clean, flat, and reliable wall surfaces when they are installed correctly. But if the support structure behind the boards is uneven, or if the boards are forced into position, the final wall may look wavy.
Fiber cement board surface dust after cutting should always be removed before painting, coating, sealing, tiling, rendering, or applying adhesive. Cutting fiber cement boards can create fine dust on the board surface, edges, joints, and surrounding work area. If this dust is not cleaned properly, it may affect adhesion, surface appearance, and final finish quality.
Fiber cement board is a practical material for modular construction because it can support fast installation, dry construction methods, and reliable wall build-ups. In modular buildings, the wall system must be strong, stable, and easy to assemble. Boards may be used for external sheathing, internal lining, façade backing, wet areas, fire-safe walls, or floor build-ups.
Fiber cement board can be used as a substrate behind brick slips, stone finishes, and rendered wall systems in selected construction applications. However, the board should not be treated as a universal backing board for every finish without checking the complete system.
