I want to show you all photos of the demo I did yesterday.
My mix was 2.5% mix, The gw and tw was added as well.
Can someone give me some advice?
Is this cleaning going to require some scrubbing? It's awfully big ...

Robert, If you let it dwell and hit it multiple times and that was the result, then you should price it out to scrub the whole thing. I did a demo on one very similar to that, a few years ago, and I hit it with a 4% mix three times and still had to scrub it to look really good. I priced it accordingly and they never did the job. Once I figured in the lift and the man hours to brush it, they just said it was too much cash. Only other thing you can try is a truck was soap, and see if it can break the tension from the emissions residue on the dome. It still might need some scrubbing.

Thanks for the advise ... It doesn't take much to "scrub" off. In fact, it's more like wiping/agitate and then hosing it off.

If you just need to "wipe," a couple microfiber mops work really well for that. The ones that are made to be dry mops. They are nice and wide, and the microfiber works better than brush bristles in these types of applications. Put them on the end of a couple poles.

If simple agitation is the difference on a relatively smooth surface, what that is really accomplishing is breaking the static bond that keeps the inorganic dirt adhered to the surface.
I would try this:
1) pretreat with TW/GW/Water mix, heavy on the TW.
2) keep it wet with another coat.
3) Treat with 3% or 4% mix
4) Rinse
5) Final Wash and rinse
The pretreatment may help in emulsifying the dirt before releasing the dead organic matter into solution. There may ultimately be no substitute for agitation with a microfiber, as Chad suggested.

I have calculated the surface footage is around 60,000 square feet.
Can someone recommend the safest way to bid something like this.
It will take a least 2 applications with a little light scrubbing.
Where should I be with:
Labor:
Materials:
Equipment:
It is simple to take 60,000 times "so much a square foot" to come up with an answer.
However, not knowing how many applications it will take to finally get the surface clean. Having to do just one application vs a possible 3x is a big difference.
I have thought about .17 square foot per application. The materials would be extra as well as the articulating lift.
Anyone have some thought on the commercial project?
Thanks,

Anyone have any thoughts about my previous post on how to price this project?

Robert, I would bid at .20 per sq. foot, plus the cost of a lift as a separate line item.
You have a large advantage, because you can clean this without a pressure washer. Sell heavy on this.
