Mark Shark Graffiti Remover is a premium graffiti remover designed for porous masonry surfaces, such as brick, concrete, slate, granite, stucco, and other similar surfaces. Mark Shark soaks into porous surfaces, releasing paint from surface and sub-surface layers of masonry to remove the paint and its shadow. Works in cold, hot, wet, and dry conditions.

Additional information

Do not dilute – use full strength. Apply Mark Shark with a pump-up sprayer or brush product onto surface. Allow to sit for 5-10 minutes. Do not allow to dry on surface – reapply to keep wet if necessary. Blast affected area with a high pressure washer. Hot water will aid in ease of removal, but product is effective in cold water as well. For toughest jobs and if shadow remains following one application, repeat the above steps a second time to finish the job. If there are doubts about suitability for a given surface, be sure to test product in an out of the way area. Mark Shark is not for use on sensitive surfaces such as paint and other indoor environments.
