Tips for pressure cleaning cladded homes
Water alone won’t get it clean!
House washing cladding be it metal, timber or PVC is a simple 4 step process if you intend on using a small pressure cleaner.
It’s usually mould and mildew that needs to be removed from your cladding and to inhibit its re growth we use a special treatment.
One of the misconceptions about power washing is that by simply using a pressure washer to blast off the mould you will insure a great result. This is not true and if your main reason for cleaning the house is to remove mould and mildew, you will soon find out that the simple truth is that you will only remove 50% of it and your cladding will still look like it is off colour. Mould and mildew is alive and needs to be killed along with its spores to ensure it’s stopped in its tracks.
To keep the cladding looking sparkling clean for longer periods of time, follow this simple 4 step pressure cleaning process.
Firstly make sure you purchase some strong bleach, approximately 20ltr for an average size house.
You will need a low pressure garden sprayer to apply the bleach. Use a 4-1 mix. If you have lots of algae make your mix more concentrated.
Then most importantly make sure you wear a respirator mask, glasses, nitrile rubber gloves and a raincoat with a hood.
Have your pressure cleaner ready to go. Work small areas at any one time.
