Cleaning colored concrete

[allamericanwash 14]

Just wanted to ask you guys, how you clean colored concrete, do you still run a surface cleaner on it? What kind of pressure is recommended? It looks like the color is at least 3/4 inch deep into the concrete.

Thanks for any advice.

Propane and a match, lots and lots of Propane.

As with any other concrete, it depends on the age, the type of soil and the surface condition. Lower psi and a good prespray is usually on my agenda with colored.

Thanks again Alan. Its just general dirt with some tire marks. I was just concerned with taking off some color. Id like to use a surfacer though, how much pressure? 1500psi hot water? Or do you use a wand on these surfaces?

All depends on the size. I have bigger tips for the surfacer, as well as a bypass on the pump, it all depends on the situation.

Too much pressure will strip color very quick. I say test with a dual lance and when you see how much pressure you can use, do a pressure check and dial in the surface cleaner if you want to use it.

How many sq ft are we talking about?

Its not that big Alan, I didnt measure, just eyed it. Good sized drive with walkways around both sides of house, and back patio area. Also the back has an area of brick pavers.

Maybe I should just drive over there and you can watch me. How much are you paying?
