Wear goggles, mask, gloves, and protective clothing before working with chemical paint strippers, as they are highly toxic.
Protect surrounding grass or plants by blocking off the area with a plastic tarp. Make sure to also block off the driveway, preventing pets or kids from entering since the area will be relatively toxic. The entire process will take up to 24 hours.
Sweep and then hose off the driveway to remove dirt, grease and debris. Let the water dry.
Select a paint stripper compatible with the type of paint on the driveway. Turpentine and mineral spirits work on most paints, but some paints require a special stripper.
Apply the paint stripper over the driveway using a long-handled paint roller.
Let the stripper set on the concrete for a set time according to the manufacturer's directions.
Scrape off the paint with a long-handled paint scraper. The paint should come off. If not, either let the stripper set for longer or apply more.
Shovel the loose paint debris into a plastic trash bag. Pack in all the loose paint and tie the trash bag tightly and discard.
Wash the concrete surface with a high-pressure hose. The stripper should have rendered the lead in the paint relatively harmless.
