Under normal atmospheric conditions HardiePlank® cladding does not require much maintenance but weather and nearby plants may affect the visual appearance of the façade cladding. Therefore, an annual inspection of the ventilation gaps, joints and fixings is a good idea, gentle cleaning with clean water is recommended.
Annual Inspections recommended
Under normal atmospheric conditions HardiePlank® cladding does not require much maintenance to maintain its strength, properties and function. Environmental impacts may, however, influence the visual appearance of the facade cladding. Therefore, an annual inspection of the ventilation gaps, joints and fixings is a good idea. Detection and repair of possible damages ensure a longer life for the facade cladding.
Impact from the Environment
HardiePlank cladding is manufactured from weather resistant raw materials and will not be attacked by algae, rot and dry rot but pollution, dirt, leaves from trees, bushes and flowers will probably have an impact on the façades appearance..
Extra diligence in coastal areas
Coastal locations can be very aggressive due to salt laden moist air and windblown
sand. It is recommended that the frequency of inspection procedures in such locations be increased and that any maintenance be enabled before damage occurs. Particular attention should be paid to the corners of cladding around windows, doors and the corners of façades particularly those facing the prevailing wind direction.
Repairing HardiePlank Cladding
HardiePlank cladding should be replaced by removing the damaged board, gently lifting the board immediately above and inserting the new board. The board is then fixed by face nailing through the top board.
Cleaning fibre cement boards
HardiePlank cladding can be cleaned with cold or lukewarm water, if necessary with the addition of a mild household cleaning agent not containing solvents. Always start from the top with well-defined areas. Rinse with plenty of clean water until the facade is perfectly clean. Test cleaning on a small cladding area should be undertaken first. High pressure cleaning systems are not recommended with fibre cement cladding, or timber, as this may damage the surface and paint finish.
