This is a quick and easy summer time project to bring hidden messages and pictures to life! It utilizes a hydrophobic spray and a cardboard stencil with your design. Where ever the spray coats the sidewalk, it repels water, so taking advantage of this property, I was able to make some really cool hidden sidewalk art around my home and neighborhood. Just note that this spray was a lot more long lasting than had originally had hoped, which isn’t an issue for me, but could be for you. Just something to keep in mind!
