How to Remove Graffiti From Concrete Wall

Therefore, removing graffiti as soon as it appears is important to avoid further damage and keep your property looking clean. While many commercial products are available to remove graffiti, you may also use household items. Read on to know more!

What Is Graffiti?

There’s something about graffiti that just screams “public place.” Maybe it’s because it’s usually done on walls or other surfaces in a public place. Or maybe it’s because some buildings are more apt to attract graffiti than others. For example, if the building is made of concrete and has a rough (non-shiny) surface, graffiti is easier to stick on that kind of surface than on walls with smooth surfaces like plaster or sheetrock. Either way, graffiti is simply writing or drawings made in a public place. And graffiti is another word for vandalism if it’s not in a public place.

13 Ways on How to Remove Graffiti From Concrete Wall

1. Using Razor Blade

If you have some graffiti that’s been painted onto a concrete wall and want to remove it, you can do it by using a razorblade. Just slip the razor under the paint and gently pull it away from the surface of the concrete. If it’s too hard to pull off, you can dampen the razor by dipping it in water or oil before using it on the graffiti.

2. Using acetone

Acetone works best in removing paint by dissolving it. You’ll need to purchase an acetone-based commercial paint remover from a hardware store and apply the solution to the graffiti. Allow a few minutes for the solution to soak in and loosen up the paint before gently scraping it away from the wall with a plastic putty knife. Sure, this process will take a lot of time and effort, but it is safe for the environment and your health since acetone is non-toxic.

3. Using a Pressure Washer

A pressure washer can remove paint from walls by blasting out the paint from the concrete. Though this method works quite fast, it is harmful to the environment and especially to your skin and eyes if exposed to a direct spray of water.

4. Using a Chemical Cleaner

Using a Chemical Cleaner to Remove Graffiti

Chemical cleaners are dissolved in water that loosens the paint allowing you to wipe it off easily. Apply these cleaners to the graffiti and wait a few minutes before wiping the paint off with paper towels. But make sure you use protective gloves and goggles when applying chemical cleaners on walls to avoid any injury or harm caused by the chemicals.

5. Using Ammonia

Ammonia is another commercial cleaning solution that can remove graffiti from concrete walls. Apply Ammonia on the painted surface and wait for a few minutes before removing it with paper towels. If you find this process too messy and time-consuming, you can use an air compressor to spray the graffiti and remove it instantly.

6. Using Nail Polish Remover

Nail polish removers effectively remove ink and paint from surfaces, but they are harmful to health when used for more extended periods. Also, nail polish remover is quite messy and time-consuming since the layers of ink and paint cannot be removed in just one go.

7. Using WD-40

WD-40 contains ingredients that work as a strong degreaser. You’ll have to apply a few drops of WD-40 to the graffiti and allow it to soak for a few minutes before wiping off the paint with paper towels.

8. Using bleach

Using Toothpaste to Remove Graffiti

Bleach is an effective cleaning solution that can remove paint from concrete walls. Pour some bleach on the paint surface and leave it be for a few minutes before wiping it off with paper towels. Though this cleaning solution is highly effective in removing graffiti from concrete walls, but its excessive use can cause harm to your skin and eyes.

9. Using Toothpaste

Toothpaste can be used to clean graffiti off of surfaces. Squeeze the toothpaste onto the graffiti, then rub it in with your fingers. Rinse the area with water and wipe away the paint with paper towels.

10. Using Baking Soda

Baking soda dissolves paint over time because of its acidic nature. It is another eco-friendly way of removing paint from walls made of concrete. Apply baking soda or paste on the graffiti and wait for a few hours before rinsing it off with water. Use a clean rag to wipe away the paint to prevent scratching the surface of the concrete wall.

11. Using Pumice Stone

Pumice stones are pretty effective in removing paint from concrete walls. Just rub the stone against the graffiti and wipe away the paint with a clean rag. This process may take some time, but it is worth spending since pumice stones don’t scratch or damage the surface of your wall.

12. Using Sandpaper

Sandpapers are also used to remove paint from concrete walls. Use wet sandpaper to prevent any scratches or damage to the surface of your wall. For this process, you’ll have to apply soap to the graffiti and then rub it with wet sandpaper, followed by wiping the paint with a clean rag.

13. Using Dishwashing Liquid

Using Dishwashing Liquid to Remove Graffiti

Mix equal parts of vinegar and dishwashing liquid in hot water. Pour this solution on the paint surface and allow it to soak into the paint for a few minutes before wiping it off with paper towels. For stubborn stains, you can use bleach instead of dishwashing liquid. Use protective gloves when applying either of these household chemicals.

Some Tips and Suggestions

Here we have given some tips on how to remove graffiti from concrete wall.

1. If you are not experienced with muriatic acid, wear gloves, wear some old clothes, make sure there are no children or animals around.

2. Use a brush to scrub the surface of the concrete.

3. The acid will break down the ink so use this opportunity to scrape off any paint with your brush or scraper.

4. Make sure you are upwind from any fumes arising from the acid. Wear a mask if necessary and make sure there is good ventilation.

5. Once the acid has turned from clear to white, you can pour a bucket of water onto it and let it seep into the concrete. Rinse with a hose afterward to remove any leftover muriatic acid or paint residue.

6. Don’t try to scrape off the paint once it has been rinsed. Instead, let the concrete dry, and then use a wire brush or sponge with soap to gently remove what you can.

7. Make sure that if your cement is an acid-resistant barrier, this is no longer needed now that you have removed all of the paint.

Can Graffiti Be Removed From Concrete?

It depends on what kind of graffiti it is and how long it has been there. Graffiti can be removed from concrete walls with a bit of preparation and elbow grease. If the graffiti is a relatively new spray paint tag, then a commercial remover can be used to remove it from concrete. If the graffiti is older and has already been painted over a few times, it can take some effort, but it is still possible to remove the graffiti.

How Long Does it Take to Remove Graffiti From Concrete Wall?

It takes time to remove graffiti from the concrete wall because several steps are involved. Plan to spend about an hour per square meter of the painted surface because there is no graffiti on the wall paint. It can take twice as long to remove it from a painted wall.

Spend About an Hour Per Square Meter

If you have a significant graffiti problem, you may need to refinish the paint on your concrete wall. For example, if the vandal spray-painted a mural, you must discard all of your existing wall paint. Then the wall will need to be newspaper-pasted and scraped off all loose paint. This procedure can take several days to dry, so plan accordingly.


Several methods can be used if you need to remove graffiti from a concrete wall. However, you should consider the paint and surface material type before selecting an appropriate removal method. In many cases, it is best to use a chemical solution such as muriatic acid or hydrochloric acid to break down the different types of paints applied to the surface.

When removing graffiti from asphalt, brick, or other porous surfaces, sandblasting may work well because blasting will cause a reaction with these materials, causing them to react against one another, which removes any traces left by the marker pen ink or spray paint.
