- The ad uses water through a stencil and is designed to fade back into the sidewalk over time.
Field notes
The homepage frames the service as a controlled contrast: a cleaned sidewalk surrounds a single untreated square, where water pushed through a stencil reveals the requested mark. It accepts logos, names, social handles, and short web addresses, while noting that bold, simple designs work best. Projects are quoted individually by location, size, and number of squares, and the stated service area is San Francisco.
