A good way to do this is to clean everything first, power wash, etc, and then apply the Demand CS.
You really don't need a high powered sprayer to do this. You only need to apply a few gallons of Demand mix. Maybe 2 gallons total.
If you want something less expensive where you can blast the side of the house, then use Bifen. It's cheap and you can mix and blast away with your cannon sprayer.... :-)
