How To Remove Spray Paint From Concrete

Have you been working on a spray paint project and got some cleanup to do? Here is the perfect guide on how to remove spray paint from concrete. Because of its nature, spray paint is hard to remove as it goes into many different layers and dries up quickly. However, it is still possible to remove the spray paint from concrete using any of the methods outlined below.

Take Care of your concrete when removing spray paint

To begin with, utmost care needs to be taken when removing spray paint from your concrete so that you don’t end up damaging it. Therefore, remember to always rinse any graffiti remover, paint thinner, or whatever solution you have used with hot water immediately. This is because most of the solutions used to remove spray paint from concrete have some chemical components that are capable of dissolving concrete.

Moreover, because concrete is absorbent, a spray paint stain penetrates much easily just like on a sponge. When removing the stain, you may have to apply extra elbow grease; making a few reapplications before getting your concrete wall or floor to look normal.

What is the Easiest Way to Remove Spray Paint from Concrete?

As we have mentioned earlier, spray paint tends to penetrate easily into the layers of concrete making it harder to remove than other paints. However, you can simplify the process of removing spray paint by using a combination of pressure washers, paint strippers, and other tools that can help loosen the layers of paint as you blast it away.

Basically, you can remove spray paint using a solution-based method or by using an electrically powered machine.

  1. Solution Based methods

Solution-based methods use a combination of chemical components that work by penetrating the paint and breaking it down separating it from any surface before it is wiped off or hosed away. These methods are effective and quick but only depending on the surface area you intend to work on. They include using soap and water, paint thinners, graffiti remover, and TSP. Because of the chemicals used, gloves, a ventilator, and other protective gear need to be worn when using these methods.

  1. Electrical powered Machines

The other cadres of methods you can use to remove paint from concrete involve the use of electric-powered machines. Although highly effective, these methods are costly in regards to the cost of acquiring the machines. Moreover, only the power washer doesn’t require a special skill set to operate and use. This leaves the sandblaster and angle grinder in the hands of professionals only. In addition, the sandblaster and angle grinder cause a lot of dust and noise pollution that may make them not ideal in some situations. However, if you are dealing with a spray paint stain that requires professional attention, these are the go-to machines that will get the job done effectively and in no time.

Does Vinegar Remove Spray Paint from Concrete?

If you don’t prefer using chemical solutions to remove spray paint from your concrete, you could as well use white vinegar o get the job done.


  1. Heat half cup of vinegar and bring it to near boiling,
  2. Cover the area stained by the spray paint stain.
  3. Dip a sponge or paintbrush in the hot vinegar and scrub the paint stain.
  4. Let the hot vinegar sit on the stain for 10 to 15 minutes until you see bubbling when the bond between the concrete and paint is broken. If it doesn’t work, reapply the vinegar until it works.
  5. Using a paint scraper, remove any loosened paint before hosing the area with warm soapy water.

The other ways you can use to remove spray paint from concrete include;

  1. Using Soap and water

This method allows you to use items easily available in the house to remove spray paint. All you need is soap, water, and a stiff-bristle brush. This method is only applicable if you are dealing with a small stain. However, you may have to scrub and rinse a number of times before getting rid of the paint stain from your concrete.

  • Using Graffiti remover

If using warm water and soap doesn’t give you the desired results, you can try using graffiti remover. Graffiti remover uses some chemical components that are designed to penetrate through the paint loosening its grip on surfaces including concrete. Graffiti removers come in different forms such as liquid solutions, sponges, pastes, wipes, trigger sprayers, and aerosol cans. It is important to read the instructions on the product label before using graffiti removers.

  • Using paint thinner or stripper

Paint thinners and strippers are solvents designed to break down paint from multiple surfaces including concrete. They offer a solution that is cheap and yet highly effective when it comes to removing spray paint stains from concrete. Some of the solvents that are known to remove paint include Turpentine, acetone, naphtha, xylene, denatured alcohol, and methyl ethyl ketone.

  • Using TSP

Trisodium Phosphate (TSP) is an effective solution that is used in paint removal. TSP comes in liquid and powder forms and works similarly to paint strippers. The thing with TSP is that not only is highly effective, it is also readily available, inexpensive ad quite easy to use.

  • Using a power washer

A power washer or pressure washer is a machine designed to shoot a forceful stream of water. Power washing is highly effective in cleaning a variety of surfaces and therefore comes in handy when you need to remove spray paint from concrete. This method used in addition to singing solutions is quite effective and uses less water. However, unless you already own a power washer, the costs of buying a new one made using a power washer are quite expensive especially if you only need to deal with a small stain of spray paint on your concrete floor or wall. Moreover, you can only use a power washer where there is a source of electricity or backup power limiting the areas you can use a power washer.

  • Using a sandblaster

One of the quickest ways to get rid of spray paint stains is to use a sandblaster. This machine works by chipping away the stained layers of concrete easily getting rid of the spray paint in no time. This method does not use any solvents and is quite friendly compared to the other methods. However, using a sandblaster requires some skill otherwise you may end up damaging your concrete floor or wall if you don’t know how to use a sandblaster correctly. Moreover, it can be quite expensive to acquire sandblasting equipment, and therefore this method is rarely used when dealing with small spray stains. With the required skills and equipment required, the sandblasting method becomes quite unattractive for small DIY projects and is mainly used by Paint professionals.

  • Using an Angle Grinder

An angle grinder works much like a sandblaster. The grinder is designed to work with different grit wheels which gives you the flexibility of working on different projects. It also makes it an ideal choice when dealing with different types of spray paint stains on concrete. However, much like a sandblaster, using an angle grinder also requires some skill set. It is also expensive to acquire and therefore unattractive especially when dealing with small projects. Its, therefore, is suited for professionals.

The above methods offer varied yet effective ways that you can use to remove spray paint from concrete. The most important thing you need o to remember when taking care of your concrete wall or floor is to also take care of yourself. The solution-based methods use toxic chemicals. Make sure you have gloves, goggles, and other safety equipment before working on any project. Moreover, remember to wash when you have finished working on your project.
