18mm moisture resistant MDF is a strong, versatile board ideal for bathroom cabinetry, kitchen carcasses, utility shelving, and boxing in pipework. It performs well in humid settings while maintaining excellent machinability and a smooth, paintable finish.

Cut precisely from moisture-resistant boards and supplied as full sheets, custom shapes, or made-to-measure panels.

Orders typically arrive within 1-7 working days. Need it sooner? Same or next-day collection is available, depending on order size.

Sheets cut to 1220 mm or 3050 mm retain a clean, factory-finished edge.
Please note: Board face colour may be green or brown, depending on manufacturer. This has no effect on performance.
