How to clean Fibre Cement Cladding
Updated: Oct 7
Fibre cement cladding is a popular choice for exterior building facades due to its durability, weather resistance, and low maintenance requirements. However, like any exterior surface, fibre cement cladding requires periodic cleaning to remove dirt and grime to maintain its appearance and performance over time. In this guide, we'll explore the best practices and techniques for safely cleaning fibre cement cladding, ensuring a pristine finish without causing damage or compromising its integrity.
9 Steps to cleaning your Fibre Cement Cladding
1. Assess the Condition
Before diving into cleaning, take a moment to assess the condition of your fibre cement cladding. Identify any areas of heavy buildup, staining, or discoloration that may require special attention. Additionally, check for any signs of damage, such as cracks or chips, that may need repair before cleaning.
2. Gather Supplies
To clean fibre cement cladding effectively, you'll need a few basic supplies:
Mild detergent or specialised fibre cement cleaner
Soft-bristle brush or sponge
Garden hose or pressure washer (with a low-pressure nozzle)
Bucket
Protective gloves and eyewear
Avoid using harsh chemicals, abrasive cleaners, or power tools, as they can damage the cladding surface and compromise its integrity.
3. Prepare the Area
Before cleaning, remove any furniture, decorations, or obstacles near the cladding to ensure unobstructed access. Cover nearby plants, landscaping, and delicate surfaces with plastic sheeting or drop cloths to protect them from over spray or runoff.
4. Test in an Inconspicuous Area
Before applying cleaner to the entire surface, test it in a small, inconspicuous area of the cladding to ensure compatibility and assess any potential adverse reactions. Wait for the test spot to dry completely before proceeding.
5. Apply Cleaner
Mix the mild detergent or specialised fibre cement cleaner with water (according to the manufacturer's instructions) in a bucket. Using a soft-bristle brush or sponge, apply the cleaner to the cladding surface, working in small sections from top to bottom.
6. Scrub Gently
Gently scrub the cladding surface with the brush or sponge, using circular motions to loosen dirt, grime, and stains. Avoid applying excessive pressure or scrubbing too vigorously, as this can cause damage to the cladding surface.
7. Rinse Thoroughly
After scrubbing, thoroughly rinse the cladding surface with clean water using a garden hose or pressure washer with a low-pressure nozzle. Start from the top and work your way down to ensure complete coverage and remove any remaining cleaner residue.
8. Allow to Dry
Allow the cladding to air dry completely before inspecting the results. If necessary, repeat the cleaning process in areas with stubborn stains or heavy buildup until satisfied with the outcome.
9. Maintain Regularly
To keep your fibre cement cladding looking its best, establish a regular cleaning schedule, typically once or twice a year, depending on environmental conditions and location. Areas close to roads tend to require more regular cleaning. Promptly address any spills, stains, or contaminants to prevent them from becoming more challenging to remove over time.
