How to Get Spray Paint Off Concrete (5 Effective Methods)

Whether it is the consequence of accidental overspray while working on a weekend project or the aftermath of vandals, spray paint on a concrete patio, driveway, or sidewalk is an eyesore. Fresh paint can be removed without too much difficulty, but spray paint dries quickly and takes more work to remove.

Concrete and other porous surfaces can collect stains, making them difficult to clean. Even though there are many graffiti removal products on the market, there are DIY methods you may use to get paint stains off of your garage floor and other concrete floorings.

5 Methods to Remove Spray Paint From Your Concrete

The following strategies may be utilized in order to remove spray paint from concrete.

1. Graffiti Remover

One of the finest ways to remove spray paint off concrete is with specialized graffiti cleaners. You may complete the task yourself if you have a bottle of effective graffiti cleaner and a firm scrub brush. Just carry out these actions.

  1. Use a graffiti-eraser spray to clean up the painted area.
  2. Scrub the surface in a circular motion with the firm bristle brush.
  3. Continue scrubbing and reapply graffiti remover as necessary.
  4. Use a yard hose to spray warm water on the concrete.
  5. Try cleaning the graffiti with hot water and soap if there is still any lingering ink.
  6. Permit the area to air dry.

Graffiti remover performs best when water is delayed until after scrubbing is complete. Spray the graffiti cleaner first, then scrub. Wash the area with warm water once you’re through. Most spray paint stains will be removed with this effective technique. Once you attempt this technique, the job will usually be finished.

Trigger sprayers will cause the solution to drip down if the spray paint is applied to a vertical surface. Avoid over-wetting the area, and think about using painter’s tape and plastic drop cloths to contain runoff.

Simply tape the area where the spray paint will be applied, and then secure the drop cloth to the tape to safeguard the surface beneath.

2. Use Paint Thinner or Stripper


Concrete can have its paint “thinned” or broken down with paint thinners and strippers. This is the strategy for you if what you need is an approach that doesn’t require a lot of money but is nonetheless very effective in its use. The application is straightforward, and the components are inexpensive.

Since paint thinner is a solvent, it can dissolve various materials, including paint. Acetone, turpentine, xylene, naphtha, methyl ethyl ketone (MEK), and denatured alcohol are among the solvents known to remove paint effectively.

Although it is made differently than paint thinner, the paint stripper also works to remove paint. Both caustic, chemical (solvent-based), and non-caustic gel formulations are available.

  1. Remove extra dirt by sweeping or wiping down the area.
  2. Ascertain that the area is well-ventilated and put on safety gear.
  3. Follow the directions on the product label when applying paint stripper or thinner to the harmed area.
  4. After the application, wipe the area.
  5. Use a fresh section of the cloth with each wipe until all paint has been removed.

You must keep the area well-ventilated if you are using a paint stripper or thinner indoors. You must put on safety gear for your hands, eyes, nose, and mouth. Some products will burn your skin and, if inhaled, may result in respiratory problems.

Choose a soy gel paint stripper like Citristrip as it is a more natural method of removing paint, usually has a more pleasant smell, and won’t harm your skin.

3. Trisodium Phosphate

Spray paint stains can be removed with trisodium phosphate. It works well as a scrubbing solution. To protect yourself from Trisodium Phosphate’s potential to irritate your skin, eyes, or airways, you should wear protective gloves, goggles, and a mask. Here’s how to use trisodium phosphate to get spray paint off concrete:

  1. Combine 14 cups (60 ml) of trisodium phosphate with 1 gallon (3.75 liters) of hot water.
  2. Scrub the painted surface with a firm scrub brush made of non-metal bristles.
  3. Apply more of the Trisodium Phosphate solution and let it sit for 20–30 minutes.
  4. Repeat the scrub, adding additional Trisodium Phosphate solution as necessary.
  5. Use warm water to wash the concrete.

When removing paint from concrete, it’s best to use a scrub brush with plastic or vinyl bristles. Concrete surfaces can be removed with metal-bristle brushes, leaving behind a pitted, porous surface. As a final option, only use a wire brush.

There are TSP substitutes available that work well but fall short of the genuine article’s power. One such substitute is borax powder, which you can find on Amazon, along with other goods like Krud Kutter TSP Substitute.

Avoid using TSP on windy days if you’re using it outside. To avoid harming surrounding plants and to have as little of an environmental impact as possible, you should limit the product as much as you can.

You must wear coverings for your hands, arms, eyes, nose, and mouth, as well as protective clothing and equipment. When working with TSP, it is important to protect your lungs with a respirator and to keep the chemical off your skin.

4. Use a Power Washer

A device that emits a concentrated, obnoxious jet of water is referred to as a power washer or pressure washer.

Power washing is a very efficient way to clean a number of materials and surfaces, and it is incredibly good at getting spray paint off of concrete.

  1. Put on safety equipment.
  2. Assemble the power washer according to the manufacturer’s instructions, then use it accordingly.
  3. Select and attach the preferred nozzle.
  4. Point the sprayer in the direction of the affected area’s edge while standing 10 feet away.
  5. Turn on the sprayer and sweep the concrete in a back-and-forth motion.
  6. Continue cleaning the impacted area until the spray paint is gone.

The best results are obtained when a power washer and paint remover are used together to remove paint from concrete. It is therefore recommended to use the power washer after applying the gel paint stripper and letting it sit for 30 minutes. This will increase the effectiveness of your paint removal efforts because a power washer removes loose paint even more effectively than a paint scraper does.

5. Angle Grinder

As a last option, you can scrape paint off concrete using an angle grinder. It’s crucial to keep in mind, though, that this technique will also remove the paint from the top layer of concrete. Therefore, it is recommended to first try scrubbing techniques and a paint stripper before using your angle grinder. However, you can adhere to these instructions to remove paint with an angle grinder:

  1. Whenever you use an angle grinder, be sure to put on thick gloves, hearing protection, and eye protection.
  2. Add a specialist paint stripping wheel to your angle grinder.
  3. Place your angle grinder so the flat surface, not the edge, will contact the concrete.
  4. Gently scrape off excess paint by bringing your angle grinder into contact with the concrete while it is running.
  5. Proceed cautiously and gently. When using the angle grinder, stop if the concrete seems to have been harmed.

Use this option only if you have prior expertise with an angle grinder. Scraping paint off concrete is a difficult task to start with if you’re new to using this instrument. Nevertheless, it’s a powerful choice that consistently removes paint off paved surfaces without using harmful chemicals.

Sandblasting and grinding both produce a lot of dust. You must wear goggles that are tightly fitted to your eyes and a respirator to protect your mouth and nose.

For the task, you need the appropriate grit and grinder size. Pick a small (4.5-inch) to medium (6-inch) handheld grinder and paint stripping wheel to keep things easy (disc).
