If so does it fade over time or do I have to do something to remove it?
If accidentally sprayed onto cement, Mark-It Blue will wear off with time. However, it is best to protect porous surfaces with a tarp, cardboard, or other barrier so that you do not get any temporary staining. You can rinse areas immediately with water to remove any colorant more quickly. Be extra mindful of sensitive stone and fabric as these may stain permanently.
