    Numerous commercially available paint removers or strippers are formulated to remove paint from concrete. Paint manufacturers often recommend the best stripper to remove their products. For paint removal, the U.S. Department of the Army recommends solutions made from hot water and trisodium phosphate or caustic soda. Soy-based paint strippers are safer to use, more environmentally friendly and often available as a gel but are more difficult to locate in stores.

    Using Chemical Strippers

    Chemical strippers are often quite toxic, so a user must ensure that there is adequate ventilation in the area that and skin and eyes are well protected. Remover is applied with a paintbrush or similar applicator. If a paint stripper is too thin to stay in place atop the spray paint, an absorbent material can be mixed in to form a thicker paste. After 20 to 30 minutes or longer, depending on the acting speed of the stripper, the paint is scraped off with a putty knife or plastic scraper. If paint particles remain, they are removed with repeat stripper application, scrubbing with a bristle brush and rinsing with water.

Additionally, power washers are generally cheaper to rent and easier to use than grinders or sandblasters.

Grinders or sandblasters are best-suited for situations where the paint is thick and extensive, and there are other irregularities on the concrete surface requiring correction. Both grinders and sandblasters can produce massive amounts of dust, so a vacuum attachment, dust mask and safety goggles are necessary.
