When you’re planning to get rid of spray paint graffiti from concrete, one of the first steps you may take involves using paint strippers on the surface.
However, after a few applications and a hard scrubbing with a wire brush, the paint still won’t budge. This is when it becomes clear that you’ll need to use a different approach to removing spray paint from concrete.
Removing spray paint from concrete is really a two step process. You’ll need to remove the top layer first, then clean the remaining paint residue with a solution and scrubbing.
Before starting the job, have a plan of action ready. The first thing you’ll want to do is mix the solution, and apply it to the damaged area. You must work on small areas.
It doesn’t take much to over-saturate your concrete and cause problems for yourself. Anytime you are working with concrete it is best to work in small sections or steps.
You can remove the paint yourself or hire a company to do it for you. Remember that if you choose to remove the paint, you should use a product that is safe for concrete.
How to Remove Spray Paint From Concrete With Soap and Water
If the offending paint is relatively fresh (say, within a week or two of application), you may be able to remove it with soap and water.
You’ll have to scrub pretty hard though. Whether you go straight for the paint with a brush or use hot, soapy water, make sure you get to work on it.
- Mix soap and water
- Use a stiff brush to scrub the stain
- Allow the mixture to dry for five minutes
- Clean with a towel or rag
How to Remove Spray Paint From Concrete With Graffiti Remover
The most popular way to remove spray paint from concrete is with a graffiti remover. Spray paint is composed of acrylic, a solvent-based paint that comes in either glossy or matte finishes. This allows the paint to be applied in a spray whatsoever rather than using a brush the old-fashioned way.
Graffiti remover works by dissolving the spray paint’s top layer, which effectively cleans it off concrete – something that regular soap and water cannot do as effectively because soap residue can remain behind on vertical surfaces.
- Make sure the graffiti is fully dry
- Spray the graffiti remover on the surface
- Let it set to work
- Remove the graffiti and any other grime with a rag
How to Remove Spray Paint From Concrete With Paint Thinner

- Mix the paint thinner with equal parts of water
- Cover the stain
- Cover the area with plastic or cardboard for at least 24 hours
- Apply a second coat of paint thinner
How to Remove Spray Paint From Concrete With TSP

- Scrub with a stiff brush
- Brush surface clean and rinse with water
How to Remove Spray Paint From Concrete With a Power Washer
If the above methods did not work, power washing can also take away the graffiti. This is a quick and easy solution to remove spray paint from concrete that’s definitely worth a try before you decide to pay for professional removal services.
- Start with a smaller nozzle on the power washer
- Spray on low pressure
- Make passes back and forth
- Move the power washer around
- Use regular tap water
- Start at one end and run the entire length of the concrete
The first time you will have a lot of build-ups, keep spraying until you do not see any more paint particles in the water. After that, continue until removed.

Sandblasting can be an effective way to keep all of the unwanted paint off your concrete surfaces. Sandblasting or soft sanding will not damage concrete like hard sanding and calcium silicate will.

How to Remove Spray Paint From Concrete With an Angle Grinder
If a graffiti tag has been sprayed on your concrete floor, you can remove it using an angle grinder and some fine-grit sandpaper. This is because it provides a significant amount of power and precision required to grind off the paint.
Angle grinders can work well for removing small paint splatters, graffiti, or larger areas of paint, like when removing earlier lines of paint for repainting.
Remove spray paint from concrete can be difficult because concrete is a very hard surface. Before you begin the task, you’ll need to completely cover the area with plastic and protect any plants or grass nearby.
This will minimize your cleanup time later and protect any other materials from being scratched or stained. You will also want to wear rubber gloves and safety goggles throughout the process to protect yourself.
To use an angle grinder, you will need to hold the rotating handle close to the concrete surface and use it to grind away the layer of paint on your concrete driveway, walkway, or sidewalk.
