There are a few reasons for the overlap marks: there is rust on the concrete or the concrete is fairly new and the top is soft.
My solution, while not eliminating lap marks, will make them less noticable: I go with the "grain" of the concrete. In other words, I run the surface cleaner in the same direction as the brushed surface of the concrete.
I hope that helps.

Kris,
You’re biting into the concrete with your surface cleaner. This will not happen on every job. Are you using and acid based chemical? If you’re not the concrete is just sub-standard. That’s doesn’t mean we should not worry about this. Simply just test and area and let it dry before proceeding over the rest. These types of surface cleaners have no adjustment up and down? If they do raise the surface cleaner so your not getting as aggressive.
Sometimes when the damage is done theirs really nothing to do. If you find that no matter how many times you go over and theirs no change. The surface has been etched. Once you etch the surface the only way to get the other areas to match is etch those areas. I wouldn’t recommend that right now.
On concrete there is a cream about a 32second to a 1/16 of and inch. This cream is done when they finish the concrete. This cream is the first layer of protection.
Kris I still have some interesting things to tell you about surface cleaners. Call me or e-mail me your number.

I am not using any chemicals in the areas with the stripes, only hot water. I believe the factory nozzles are 15 degrees? Would it help if I change them to 25 degrees? Ron, you are right, there is no way to adjust the height. If I do the test area and it stripes, do you just recommend I don't do it?
25 degree tips might help, kris i'm going to reply with some more later,, got a ball game.
Kris,
Are you sure that is not stained areas from tire tracks? I do a 50% overlap when doing drives and walks. Never have etched the concrete. I do know that certain stains that are there before the job just won't come out. Did the the customer notice the marks after you were done?

Make sure both of your spray tips are correctly aligned. You should find that it is less noticeable after it dries.
