Pressure and Newley Poured Concrete

S

Speed's wash

New member
I had a contractor call me for pressure washing the garages and driveways of new homes. Has anyone had any problems with their surface cleaners tearing up the concrete? The contractor stated that the last guy they had tore up the concrete with his wand and caused about $6000 in damages. He probably used a 0 degree nozzle and had no idea what he was doing. She also stated that the guy had a cold water machine so I'm sure he was one of the splash and dash guys.
I am going to meet with the contractor and give her a demonstration and I was thinking about using my Steel Eagle surface cleaner.
I know that the concrete is newley poured so I need to know if I can use my surface cleaner or what degree nozzle to use if I use a wand.

Thanks
 
I'm sorry that did not come across the right way. It just made me think that he did not know what he was doing. There are many situations where a cold water machine is the right tool for the job.
 
If the concrete is cured it definetily should be good. Unless that guy had a Chevy Small Block hooked up to his PW I don't see how he could destroy that concrete. I've had my nozzle sometimes to the very ground (For when I'm removing Gum or Paint) and it didn't chip away too much. Nothing to where you would notice. I could see that on older concrete.

Actually correct that. I pressure washed a foundation for guy who's house caught fire and burned to the ground. I was suppose to pressure wash as much of the black off that I could. In the worste parts if I stuck my nozzle real close it would chip off peices of the foundation wall. But that concrete went through a hot fire. But the driveway, Garage and the floor of the foundation was ok.

Also some of the builders can be full of crap. I use to work construction (not pressure washing) and learned that some of those builders are the cheapest corner cutting people on the face of this planet. He may of tried cheaping out on the concrete or something. You never know. But I'd go give him a demo and if he doesn't like it just say "OK' and pack up your stuff and leave. Also after that if he calls you back I wouldn't go back.

That is why I like residential. A little easier to deal with people.

what are you trying to remove from it? As long as it has been down 30 days you can use whatever reasonable method without damage. Use you surface cleaner first as it is the least harsh and most uniform way to clean. but it wont remove the bad things that a good hot water rinse will. If he asks you to fix the screw ball's mistakes tell him you can't. Because you can't.
