Hi Been pressure washing for a couple of years now as a bolt on service.
Never had cause to use Hypo on any jobs before but I have one next week that has the grey/ black algie spores in a sheltered place on a patio which is about a quarter of the job. Have bought some Hypo that is 15% so wondered if anyone could advise correct way to use it.
Do you wet area first? Dilute the hypo ? spray on or pour on ? would you Hypo the whole area? Do you leave on for 10 mins or 10 hours? rinse off or scrub off ? avoid plants /grass areas? Any advice greatly appreciated
