Deep Clean the Concrete
The first step will be clearing the area of dirt or debris using a vacuum cleaning or broom to ease the paint removal process. You can also scrub the area with warm detergent water and a broad wire brush. If you are using a phosphate-based detergent, be sure to wear goggles, long sleeves and a pair of gloves.
