New concrete?

Hello everyone, I am new to this forum but have been in the business for a few years. I have picked up TONS of valuable information reading through these forums but have have not been able to find much on washing fresh concrete. I’ve been doing new construction cleaning for some builders for awhile and I haven’t found a good way to clean fresh concrete. They are spec builder so they complete houses within a month. There’s lots of red clay here so getting that out of fresh concrete driveways is my problem. Any help would be greatly appreciated! Thanks

Either no one knows, or …

So…Sure, I’ll tell you !

Call Jim Gamble at 510-612-0437…but not before 10 am PST. I sleep in.

Working 30-60 days a year, then the other 305 days watching the grass grow is tiring…LOL

Seriously, Call me…I will help almost anyone who asks.

^jim knows!

Would to get some of this info also. Need to clean some fairly new concrete and don’t want to take the cream out of it.

Never use high pressure. Mix 2 gallons muriatic with 3 gallons of water and downstream it onto a small section at a time then rinse with low pressure. Works great for getting red mud stains out and won’t take the cream off.

What are you using for respiratory protection with that?

I would like to know aswell, I actually have some work coming my way with new constructions and don’t want to damage the new concrete either. I will mostly be dealing with tire marks and overall just dirt. But a little worried about messing something up.

I personally don’t use a respirator when I’m spraying small amounts at the ground but I would agree that it’s a good idea to use one. Most dirt will come up with a rinse, the red mud/clay will require the muriatic. Just be careful. Work small sections at a time and don’t let it dry. I put a small amount of surfactant in my mix so I can see when I’m spraying my mix. NEVER use high pressure on new concrete and be careful with the acid. Watch for overspray. I do it exactly how I mentioned and haven’t damaged anything.

Do a search on this forum for F9 Barc. It’s usually used for rust and battery acid stains on concrete but it might also work on red mud. Just a thought.

Soft wash systems TERRA WASH says it’s for dirt…http://www.softwashsystems.com/terrawash/
