COIT’s Guide to Removing Paint Stains from Concrete
When you’re painting exterior areas of your home, spilled paint on concrete can be a bit of an eyesore. To remove paint stains from concrete, follow these step-by-step instructions.
Removing Concrete Paint Stains with a Power Washer
- If the paint stain is on exterior concrete, your best bet is investing in, or borrowing, a power washer.
- You can even rent a power washer for a relatively affordable price.
- While cleaning the paint stain, be sure the stream of water is not too narrow, as you’ll want to avoid leaving marks on the concrete.
Removing Concrete Paint Stains with Chemical Paint Stripper
If you don’t have access to a power washer, consider trying another set of steps to remove the concrete paint stain using a chemical paint stripper
- Buy chemical paint stripper that’s designed to remove oil-based paints.
- Following the manufacturer instructions, apply the chemical paint stripper anywhere from 1 to 8 hours. The label should specify the appropriate time period, so be sure to check before you begin.
- Then, scrub the affected area of concrete with a scraper or a wire scrub brush.
- You may have to repeat these steps if necessary 2 to 3 times to remove all paint residue.
- After concrete paint stain is completely removed, be sure to clean the affected area using a power washer, if you have access to one.
