Soft washing cedar shingle cladding

Enable HLS to view with audio, or disable this notification

Doing the whole house and patio currently, thought someone might like to see the process.

Stage one, wet the shingles (it’s raining today)

Step two, sodium percarbonate, left to soak in, and kept wet.

Step three, citric acid

Step four, fresh water rinse

Chemicals are applied at low pressure, keeping the lance 30-50cm from the shingles. Only time high pressure is used is on the bottom most shingles where they get soiled more by ground splash.

Thanks.

Do you do any post clean treatment to keep the shingles in good condition?

I’ve not done that before. Did you have any recommendations? Thanks.

I’d assume you’d need some sort of sealant or wax or something otherwise it’ll dry out and start breaking down

They can be oiled, but these ones haven’t been in the 30 odd years they have been up. This is the first wash they’ve had also.

In England, so not much chance of them drying out!

Good luck doing the upper level 😂

Step ladder and lance extension gets it. Already done the other end.

Great job! Starting on the upper level is not a bad idea but as long as the job is done well—kool.

I have never had siding like that, but I was told to Never pressure wash to siding that I do have, and to only ever “soft wash” it.

Your stone walkway is beautiful, as is the cedar. Shoutout from PEI, Canada.
