Sand blasting is the cleanest, cheapest and fastest way. Many rental companies rent sand blasters or you can hire it done. It requires no chemicals and you only sweep to clean it up.

Request: Removing Paint From Concrete

How do you remove paint from a concrete driveway?

RE: Removing Paint From Concrete
You can purchase a rubbing stone from a hardware store. They are used in smoothing rough concrete. If you have a painted concrete slab and want to repair warn or flaking spots, rent a concrete grinder and it will remove scaling paint and bonded paint. Then follow the instructions for proper etching/sealer and then apply a new coat of colored topcoat. Most people forget to read the prep instructions until the hard work they have done fails to last.

I attempted to remove very old paint from my concrete steps with a pressure washer with very little success. I only have one or two coats of paint to remove, and the paint has even worn off in places just from age. However, I increased the pressure on the nozzle as much as I could without damaging the concrete, but still only a very small amount of paint came off.
Am I doing something wrong or is there a better method to remove paint from the concrete, like paint remover or some other chemical? I should add that these steps have a rough not smooth texture to the concrete. Please help! Thank you!

You might try calling a paint store or a concrete place if you don't find an answer on here that works. Good luck (06/29/2007)
My guess would be that the pressure of the washer isn't strong enough to take the paint off. Most of the home-type pressure washers aren't strong enough to take anything major off of anything. We had one and it didn't work well at all.
We purchased a new industrial strength washer last year and trust me, if you aren't careful, you'll be pointing at wood/concrete one sec and air the next. lol It will eat it up quick. Paint is gone in a few seconds no matter what it's on. (06/29/2007)
