Old paint on concrete surfaces can be a real eyesore, but many people aren't sure how to remove it. Luckily, you can eliminate old paint from concrete under most circumstances following a simple procedure.
Use the pressure washer to loosen the old paint from the concrete. Begin on a low setting and slowly raise the setting so as not to damage the concrete. Proceed to Step 2 if any paint remains on the concrete.
Open the container of mineral spirits. Pour a small amount on the paint stain. Use the wire brush to scrape away any remaining old paint from the concrete. Work quickly before the mineral spirits evaporate.
Sprinkle a small amount of dirt on the concrete to eliminate the light colored areas created by the pressure washer, mineral spirits and/or wire brush. Use your shoe or boot to massage the dirt into the concrete until the color is blended into a consistent balance with the rest of the concrete. (Skip this step if you plan to paint the concrete.)
