Help!

As most of you know by now, I often will work in a variety of styles and media. This time however, I am reaching out to you guys to help me find a solution to a project that I am working on. The project consists of finding some sort of media that can be used on concrete walkway that will give the effects of a pastel painting and would stand up to the elements here in Minnesota. That includes everything from; foot traffic, rain, snow, snow blowers, salt and all other fun elemental properties. I recently just came across a polymer outdoor paint called FolkArt Outdoor, but am curious if anyone has found a product themselves or has worked with anything. I have a photo that I have attached here to give you an idea of the space. It is the front of a great restaurant that needs to have the same great looking feeling as it does inside. Any help would be greatly appreciated!!!!
