I did it at my daughters condo. Came out great. Joanns had several stencils, rocks, bricks, fences (not an option). I base coated with a grey outdoor craft paint, then sprayed over the stencil with a brick color spray paint. I was afraid to go any further with trying to shade with spray so I used a brush. Fun to do and if you don't like the outcome..paint over. Also it must be clean to start with and sealed when finished. Good luck!
