It took 3 full days.. A lot of work more than I cared to do, but my reputation was on the line, ( I was going to make that roof look nice even if I had to scrub it with a tooth brush ) Lol..
I had to put 3 coats of mix and rinse 2 times...
This roof is 40 to 50 years old it had never been cleaned, it had a carpet of dirt and mold on it that was abou 1/4 inch thick... I'm happy with the way it turned out.
THANK YOU GUYS!!! For all the advise I could not had done it without you..
