Tapelady's Note: Spray chalk is a popular selling item for us. It is safe to use outdoors and will be washed away by weather eventually. If applied to a street, sidewalk, or parking lot, it may last for weeks before it is totally gone unless you wash it off with a power washer or scrub it with a broom and water.
