Sounds like a great product... but!
I really need something in powder formApply it with any type of sprayer, mop, watering can or brush
I'm actually going to use that on driveways. For roofs, I'll stay with the aluminum sulfate.Pool clorine. pumpup sprayer. stay up wind.
I am in the NW of Oregon where moss is inevitable....:whistling2:
I am in hopes that some of you pressure washing folk have a few ideas for me.
I am in need of a powdered product for a roof. A detergent would be fine if I only knew which one works. Something evironmentaly safe would be better if it's in powder form. The pitch of the roof is too steep and the comp roof is too old to walk on for the most part, but there is an area near the back I can get on and powder down the center of the peak somewhat safely....
Good article here (IMO) on the various maintenence and long term fixes for moss, lichens ect. Most of the powders are available at garden shops in the big box stores.
The fixes with the sulfates aka sulphates are long term and require cycles of sunlight.
For killing it off initially, the bleach and TSP mix is good.
An overall suggestion might be to hire a pro pressure washer and scope out how its done. If ya start blowing liquid at high pressure at comp roofing in the wrong direction, ya might run into another famous saying. "I'll see you in court."
What do you do with the runoff? Cover plants? Keep them wet? Keep the siding wet for the house that may not haver gutters?
I ask this because of the bleach.
