I stained our concrete patio using Quikrete concrete etching stain. I used a garden sprayer and applied the stain in a circular motion. Check out my blog post: http://beauxrevesamore.blogspot.com/2012/07...

Per staining a walkway ... most walkways have a rough finish, as opposed to patios and garage
floor finishes, which are smooth. Don't think you would get the same effect, or sheen, in that case. But, I've never tried it, so I can't really say. Looks great!
