As someone who has actually removed graffitti I can recommend a power washer which will remove paint, but you need to be careful as it will also remove the concrete if you are not careful

Well, Actuary97, what I had in mind was rather, if it's so hard to remove
it might be an option for painting/"air-brushing" concrete?

I'm a bit discouraged with the "art stains", they've all faded.

I tried some thinned out latex and it scrapes off easily with a fingernail
after over a week on. I'm testing spray paints now.

Spray paints are so easy to shade and tint. I love the look on other jobs I've done.
You can get wherever you want with fairly basic colors and black.

I don't think the little graffiti rascals bother with sealer ;o)

I have had good luck with airbrushing exterior latex mixed with bonding agent and thinned with just enough water to make it flow or spray. None of my pieces get any foot traffic but have been out in the So. Fla. elements (i.e. rain, harsh sun, hurricanes) for the last two years and look just fine!

As a friend of mine told me when I was first starting - bonding agent will make paint stick to anything! We paint our concrete/stucco houses with exterior latex after all - without the benefit of the bonding agent and it stays for years!

I apologize, but I'm not sure if you are asking how to remove unwanted spray paint from concrete or how to get non-spray paint to stick to a walk-way.

Water-based paint stripper should rid you of that blue from the concrete and is kind to the environment. 3M makes a great one!

A, I'm sorry I was too ambiguous, I'm looking for concrete paint or stain
that will last at least a decade without fading.

It doesen't have to spray, I'll brush it on if I have to.
I just like the simplicity of spray cans and the ability to switch color
every few minutes. A sprayer has to be cleaned out between colors I think?
and exterior latex paints are about 12 bucks a quart, the least you can buy.
Spray paints are cheap, come in many colors and mix readily, wet or dry.
I thought about graffiti, which are done in much the way I like to work
and since they appear to be so hard to remove, I thought the technique might
be an option.

I'll have to research bonding agents, don't know anything about them
though I'm sure there are several posts on this forum I can go check.
Do they work with acrylic craft paints too?
I just read through a thread on leaf painting that was very helpful.
Thanks!

I surely hope we get a number of responses here because I appreciate the notion of spontaneity that the spray paints can give and I have no suggestions to contribute.

But if I were using much spray paint, I'd be concerned about possible dangers of exposure so I want to remind all of us to be careful and follow the instructions. It is not just the solids, but the chemical vehicles that deliver the paint that can damage lungs.
