I used to use this method until I got the tank system. All I do now is wet the SFG and then spray some hypo along and wait 10mins then go back and clean with cold water from the pole. This is the best and quickest method I have come to realise.
Being in Scotland you probably spray half the country without realising it. You’ll no doubt also ruin most of the clothes you’re wearing, get it in your hair, eyes and cover the owners garden.
If you’re now going to say you wear PPE to protect yourself it’s not going to be as quick as you’re implying.
Spraying with my wfp with jet nozzle from my PF trolly. Yes I have ruined many hats, caps and goggles but that's what I buy them for. The method suits me until something goes wrong I'll keep doing it.
You spray bleach through a PF pump?
Yes, paid extra for a chemical pump and always rinse with water when finished. I used to use degreaser but once I went on the Softwash course I began to use hypo. It leaves a better job and saves alot of time so use that now. I have regular customers that I spray their roofs with hypo every 2 years. I spray mine every year now and it still looks like new and it was replaced 15 years ago. I always get asked what I do to keep it looking new and get new customers .
