Preparing your buckets in advance helps streamline the process and keeps your tools clean and effective.
Please remember to set these buckets aside, out of reach of children and pets, before starting the paint removal.

Scrub the Spray Paint With Dish Soap and Water

If the paint stains are not too old or deep-seated, a good scrubbing with dish soap and water can effectively remove them. Start by mixing a few drops of dish soap in a bucket of warm water. Soak your scrub brush in this soapy solution, then vigorously scrub the painted area. The soap acts as a mild abrasive, helping to break up the paint, while the scrub brush’s bristles get into the concrete’s pores to lift the paint. Remember to frequently rinse your brush in the bucket to remove the paint particles and keep the bristles effective.

Scrub the Spray Paint With Dish Soap and Water

Once you’ve scrubbed the entire area, rinse it thoroughly with clean water to remove any soap residue. If there’s still paint remaining, you may need to repeat the process or proceed with a stronger method like a paint stripper.

Apply Graffiti Removal Spray

If scrubbing with dish soap and water wasn’t enough to remove the stubborn spray paint, you may need to step up to a graffiti removal spray. These products are specially formulated to break down the bonds within the spray paint, enabling it to be scrubbed away more easily. To apply, first shake the can well, then spray a generous amount directly onto the painted area. Allow the product to soak in for a few minutes – some particularly stubborn paints may require up to 10 minutes of soak time. Don’t let the graffiti remover dry out, though; if it’s starting to dry, apply a bit more. Always follow the specific instructions on the graffiti removal spray you’re using to ensure effective results.

Scrub Vigorously With a Brush

Once the graffiti removal spray has been given ample time to soak, it’s time to get to work with your scrub brush. Use firm, circular motions to scrub the treated area thoroughly. The mixture of the graffiti removal spray and your vigorous scrubbing should start to break down and lift the spray paint from the concrete. It’s important to maintain a steady pressure, but avoid being too aggressive to prevent damage to the concrete’s surface. Rinely your brush in the bucket of clean water intermittently to remove the paint particles and to keep the bristles effective. After scrubbing, you should start to see the spray paint fading or coming off. If the paint still remains, you might need to reapply the graffiti remover and scrub again.

Rinse With Clean Water

After the scrubbing process, it’s crucial to rinse the area thoroughly with clean water. This step removes any leftover graffiti remover, loosened paint particles, and residue. Use a garden hose or a pressure washer, making sure to cover the entire treated area. Be cautious of runoff; both the paint and graffiti removal spray can be harmful to plants and certain surfaces. As you rinse, you may notice that more paint is coming off – this is a good sign that your efforts are working. Continue rinsing until all the soap and loosened paint are washed away. Allow the concrete to dry naturally, and then assess if any spray paint remains. Repeat the graffiti remover application and scrubbing steps if necessary, followed by another thorough rinse.[3]
