I have seen that video a while back and they bash the 2-step method and say that it damages paint.
Obviously they did not know how to do it the right way or had inferior chemicals or are just saying what someone else said about 2-stepping without really knowing how to do it and what chemicals to use. I have been 2-stepping for years now and know a lot of guys that 2-step fleets of trucks all around the country that have not caused any damage to painted surfaces so that tells you that he either did not know what he was doing, had inferior chemicals or is just repeating the nonsense that others have fed to him and he never found out for himself to see if it does cause damage, some call those kind of people talking heads. hahahahaha
It is good that people out there will pay for rinsing that much concrete, I bet anyone in that area could go and stencil some of that work and show a better or deeper clean if they wanted to.
You can go and nit-pick more of their stuff if you wanted to like using way too much pressure to wash buildings, not cleaning concrete that good (just rinsing and no before/after pictures or video to show the level of clean) and wasting a lot of water (surface cleaners are a lot more efficient when cleaning and not wasting water) when compared to wanding the surface (rinsing instead of cleaning the concrete) and what he says about the competition and other things but he does have a huge company, multiple trucks and can do a lot of work in a nite for those companies that want that level of service that he provides to them.
I have hired and fired guys the same day or the next day that were saying how they can wand concrete as good or better than what you can do with a surface cleaner, they just had no clue as they have not used surface cleaners before or were told that surface cleaners do not clean good. It is a shame that people out there will blindly believe nonsense like that and then you show them the proof that the surface cleaners do a great job, give a uniform clean and are more efficient at using water, it is hard for them to believe it and some will still not believe as that is all they know and they are not good at changing their beliefs since they have been brainwashed for so long.
I had a few guys come from a large company here that were wanding like crazy fast (like in the video) and I go back and show them how much they missed, how with even less pressure and a little closer to the surface it gets cleaner and when you use the surface cleaner it gets clean as long as you don't walk too fast, they are just dumbfounded and baffled when they see the results. I never could get them to slow down to actually clean the surface as they were trained to walk while wanding as fast as they could or walk with a surface cleaner as fast as they could so they could finish fast to impress their manager and then go sleep in walmart parking lots or the whataburger parking lots until it is time to go home, what a shame! They are basically paid to put on a show of how fast they can move the wand or surface cleaner, not actually clean.
I have seen these guys spray some soaps down before working and in theory, it should make it so they can work faster but when using the surface cleaners, they are moving so fast there are swirls over the whole area so they are walking way too fast or their soaps are watered down too much or both because they are not cleaning, just putting on a show.
Imagine a 4gpm machine and a big guy surface cleaner or 30" steel eagle surface cleaner and the guy is walking as fast as he can, we all know what the concrete will look like and that is what they offer their customers. Too bad the managers on duty don't come outside and inspect the work, those guys would be ran off the property and they would lose that huge contract if they did not improve their level of cleaning.
Now I don't hire anyone from other companies because there are just too many bad habits to try to break and their idea of cleaning is a lot different from mine as my customers will not pay for what those guys call clean, they will pay when the job is done and the surfaces are clean.
