Care & Maintenance

Annual Inspection
Typically, Marley Weatherboard products maintain their strength, properties, and function without any maintenance. However, weathering can affect their visual appearance. To ensure longevity, it is recommended to inspect the ventilation gaps, joints, and fixings annually and address any possible damage. This will help secure a prolonged lifetime for your cement board cladding.

Cleaning the Marley Weatherboard
To clean the cement cladding boards, use cold or lukewarm water and add a mild household cleaning agent that does not contain solvents if necessary. Start cleaning from the bottom and focus on defined areas. Rinse with clean water until the fibre cement board is completely clean. Before cleaning the entire surface, it is advisable to test the cleaning method on a smaller area to ensure that it works effectively.

High Pressure Cleaning
Warning! Please be aware that using a high-pressure cleaner on fibre cement cladding can damage the surface. It is not recommended to use this method of cleaning.

Moss & Algae
To remove moss and algae growth, you can use cleaning agents that are commonly found in the market. However, it is important to be cautious and ensure that the cleaning agent will not damage the surface of the weatherboard cladding. To ensure compatibility with 100% acrylic latex paint, check with your cleaning agent supplier and follow their instructions when applying it. It is suggested to perform a small test on an inconspicuous area before using the cleaning agent on a larger scale, to ensure that it will not affect the colour of the plank or panel.

Efflorescence is a white, powdery deposit that occurs naturally on cement-based building materials like bricks, cement walls, grout, and fibre cement. It is caused by a process in which moisture brings salt crystals to the surface, dries up, and leaves a chalky residue. Efflorescence could also indicate water intrusion behind the siding, which should be prevented by properly covering all openings and avoiding overdriven nails. Efflorescence will usually disappear under the influence of normal natural weathering.
