I dragged out my spare 50 footers for this job, had to put a weight on it so it wouldn’t fly off.
And this is after a post treat or before?
Before.
I should say, this is right after I hit it with 3% from my 12v. Probably a minute after.
It still looks dirty to me unless it’s just the color of the concrete. What size nozzles are you using? I wonder if it wouldn’t hurt to use a little more psi. I believe most of the concrete you do is older so a little more psi won’t hurt anything and might help. Maybe you need to do like firefighter4hire and just use SH and brown stuff and don’t even use a surface cleaner. You’d have to make room for that 12v though.

Trying to remember, I think they are four 25025’s.
Thing is, I just did an aggregate driveway and had zero issues, came out perfect. Smooth concrete hates me.

Did your post treat lighten it up some?
I just don’t think the striping is as noticeable on aggregate. If you have issues with it I bet it’s there.
I’d throw in the #2 nozzles just to see what happens. Not sure how much more pressure you’ll get with your engine though. Why don’t you take a video of yourself doing a driveway to and post it. Maybe you’ll get some pointers.

Dunno, it’ll take a day or so to lighten.
Could be the nozzles… We did a 5.3k sq ft. driveway with 4 gpm 4k psi machine today… With pretreatment & post-treatment…250 ft of hose. The surface cleaner nozzles used here, will pull from the injector.

Thanks for posting, I love seeing what people do in other parts of the country.
I don’t think I’ve seen a driveway that big in my area made from concrete, wouldn’t have a clue how to bid it either other than .12 sq ft. Did they have irrigation hookups down the driveway or did you haul water around?
Oh man we get .25 here. We usually run a long water supply hose from the house.

I’m surprised you get that much in Kentucky. I think that’s considered high just about anywhere in the country. I’d be pushing flat work like crazy if I were you.

I’m in Kentucky and get .20-.25 all the time. Sometimes .30!

I guess on average I go for .20 but smaller jobs are .25.

Smaller jobs have minimums for us, unless we are there doing other work. Then we price accordingly.
We wash this driveway annually (0.15) per sq. ft, also windows inside and out. Rates will vary on staining and scope/size, of each job.
As for water, we just tap into the spicket…no need for buffer tanks running a 4gpm… pulled 250ft hp hose from trailer and finished in 4.5 hrs

Thanks for the reply, I’m running an 8 and would chew up a ton of water. I bet I would drain my tote several times on that drive. I haven’t tackled one (or hacked one) that big yet. Maybe I need to move to Kentucky, hear they got a lot of work and pay well there 
I don’t get it, they pay .25 for concrete cleaning but don’t want to pay for deck staining? Weird market you are in.
Heck, I’m starting to get envious of others on here, I get bizzaro jobs, but I am new so who knows. Population density isn’t really happening here (unless they are first cousins) if you get my drift…in the boondocks.

I’m in Kentucky and if I qouted .25 for concrete, I’d be laughed all the way back to my truck. I just landed a 8,775 sq ft driveway at .12 per sqft. .20 would have been $1,775 - no way they’re going for that.
Oh, so you are saying don’t move to your part of Kentucky, move to DC Brocks part of Kentucky (if I wanna make bank on concrete jobs)
