Fibre Cement Decking Care Guide
Fibre cement decking combines long-term durability with effortless maintenance. Designed for both residential and commercial spaces, it provides a fire-resistant, rot-resistant and insect-proof alternative to timber and conventional composites. While the boards require very little upkeep, occasional cleaning will help preserve their premium finish and ensure lasting performance.
This guide explains how to clean, maintain and care for fibre cement decking throughout the year, helping you get the best from your installation in any environment.

Routine Cleaning & Maintenance
Fibre cement decking is built to handle the toughest conditions, but routine cleaning keeps it looking its best and ensures effective drainage and safety underfoot.
Cleaning Steps
Sweep: Remove dust, leaves and debris using a soft broom or brush.
Wash: Clean using warm water and a mild detergent with a soft-bristle brush or cloth.
Rinse: Hose down or use a low-pressure washer (<1500 psi) to rinse away dirt and soap residue.
Dry: Allow the surface to air dry naturally.
Maintenance Tips
Frequency: Clean once or twice per year, or more often in coastal or heavily shaded areas.
Avoid: Harsh chemicals, solvents or abrasive pads can damage the surface coating.
Drainage: Inspect drainage routes and joists, remove debris to maintain airflow and prevent pooling.
Regular cleaning helps maintain both the appearance and longevity of your fibre cement decking boards.

Seasonal Maintenance Tips
Fibre cement decking is engineered for year-round reliability with minimal seasonal attention.
Spring: Rinse off to refresh the surface after winter. Check fixings and substructure components.
Summer: A quick wash keeps the deck looking pristine. No sealing, oiling or staining is required, the boards are factory-finished for durability.
Autumn: Clear leaves and organic debris to prevent surface staining or algae growth. Ensure gaps and drainage channels are free from blockages.
Winter: The boards resist frost, warping, and rot. Avoid de-icing salts, which can leave surface residues.
With this simple maintenance routine, your fibre cement decking will continue performing flawlessly across the seasons.
Stain, Scratch & Mark Removal
Fibre cement decking surfaces are extremely durable and designed to resist most household stains, but prompt cleaning ensures the best results.
Mud and stains: Clean using warm soapy water and a soft brush, then rinse thoroughly.
Algae or mildew: Use a biodegradable outdoor cleaner formulated for mineral-based surfaces.
Scratches or scuffs: Light marks can sometimes be reduced with fine-grade sandpaper or a manufacturer-approved touch-up, depending on the board finish. Always check technical guidance before sanding.
Fibre cement decking boards will not absorb stains, swell or warp, maintaining their appearance for decades.
Long-Term Durability & Colour Stability
Fibre cement decking boards are built for lasting performance and visual consistency.
Colour Stability: The boards are engineered to resist fading and maintain consistent colour long-term.
Structural Integrity: The material offers excellent dimensional stability, it won’t suffer from thermal expansion and won't swell due to moisture absorption.
Inspection: Check boards and fixings once or twice a year to ensure everything remains secure and aligned.
Lifespan: When maintained properly, fibre cement decking typically exceeds 25 years of use.
