finished that job eailer today. the front walk way and the drive way took me an hour and a half to do. yesterday the back patio took me about 45 min. So total i am looking at around two and a half hours. I was pretty surprised!! LOL will put pics when i get my camera back.
Mark, the machine im working with is a 5 gpm. I am also going to get with you on putting together a downstream set up.
Oh Doug, the bleach mix worked great btw. I applied it by pump up and let it sit about 10 min. no site of the green aread at all!!
