Can anyone look at the to attached pics and tell me what maybe going on?
I'm wondering if one problem is that I should have moved faster and probably removed more surface than totally neccessary. However I am also perplexed by the second pic which shows a section washed on the left and untouched to the right. At the top of that pic I'm trying to figure out what caused the swirls on both sections. And don't fear I tested on my concrete not on a customer's. I'd rather I have to live with my mistakes than one of my customers have too.
Just for info I have a 4.3 gal/min, 3000 psi hot water machine. I was using the Hydrotek ATZ3 surface cleaner which I believe has a 19" path and has two number 2 fifteen degree tips. And I used no chemicals, only hot water.
