  1. Hi everyone, first post here! A few other plus factors for percarbonate are that it's an antifungal and antimicrobial - translate mold and mildew killer yet it does not harm plants in modest concentrations.. On roofs we spray an initial coating at about 2 to 4 ozs per gal after removing heavy growth with a mild 2 - 300lb wash. We either wash the rest of the property while it soaks or leave the property and go wash something else. A final rinse is ok but really not required as the chemical actually becomes inert after about 6 hours and leaves no discoloration. We're in New England so obliging rainstorms wash off the residual dead particles. Drier climates may need a standard garden hose rinsing after treatment. Beware of strong concentrations on paint. Vinyl siding mild solutions neutralize most mold problems. Super on decks but coat evenly and go do something else for an hour or so while it works but make sure it stays wet. Dry outs can create patchy appearance. Percarbonate - GREAT STUFF!!! Phil H ColorMasters Power Washing Service www.colormasters.org
