  1. 1

    Wash the cedar siding with mild detergent and scrub it with the brush to remove any debris, dirt and mould.

  2. 2

    Rinse the siding with a garden hose to remove any traces of the detergent.

  3. 3

    Spray the cladding using your power sprayer, remembering to keep the top of the nozzle at least 30 inches away to prevent damage.

  4. 4

    Inspect the cladding for any loose or broken areas. Cut off any damaged areas carefully.

  5. 5

    Cut a new piece of siding to fit the gap left behind by the section you have just removed. Nail it into place using galvanised nails, to prevent rusting. Use a utility knife to cut pieces for small areas.

  6. 6

    Treat the new piece of siding with a UV blocker sealant to prevent the wood from turning grey over time.
