How to Remove Spray Paint from Concrete?

As mentioned above, some spray paint removal methods from concrete are less costly, and some are expensive. Following are some important methods you can easily use at home with less effort and cost.

Method 1: Using Soap and Water

If you are tired of following other expensive ways to remove spray paint from concrete, this is the best method I recommend. Hence using soap and water is not only good for removing water-based spray paint but is also useful for oil-based spray paints.

Required Material

Procedure

1. Take a clean bucket or any other beaker and fill it with warm water
2. Now add some amount of soap and make a solution
3. Prepare the affected concrete surface with warm water and keep it wet
4. Now add some amount of warm water to the affected surface and then add the soapy water prepared in the second step
5. Now allow some time to react the soapy water with surface
6. Rinse the surface with warm water after the soapy water have enough reaction
7. Take the towel and clean the surface such that it is absorbing all the water from the surface

Pros

• Easy and affordable to implement
• It is eco-friendly and does not emit foul-smelling or environmental chemicals.

Cons

• It’s not useful for dry spray painted surfaces and porous concrete surface

Method 2: Using Trisodium Phosphate (TSP)

Trisodium Phosphate is an important chemical also named sugar soap. Using TSP has been an effective way for concrete and all other spray paint surfaces for decades. You must note that TSP is a highly toxic chemical that irritates the eyes and other sensitive body parts. So, wear a complete safety dress and glasses to avoid irritation, allergies, and injuries.

Required Material

Procedure

1. First of all, wear a safety dress, goggles, and gloves. A respirator is required when you feel breathing issues during this process.
2. Now mix some amount of TSP powder in one bucket of warm water
3. Throw the solution of the spray-painted concrete surface
4. Allow 30 minutes to mix up the solution to mix and react well with the surface
5. After that time, you will see that the paint started to remove from the surface
6. No wash the surface with warm water and see if the paint is removed completely
7. Sometimes the paint does not remove completely because the paint is too dry, throw the solution on the surface, use a brush to rub the solution with the surface, and wash the surface with warm water.

Pros

• Easy and effective to use
• Requires less time
• Affordable

Cons

• It’s not much eco friendly
• It can irritate your eyes and cause allergies in other sensitive body parts.

Method 3: Using Power Wash

A power washer is an important device that pushes off all the substances, including spray paint, mud, and others available on the surface. Ren Wash advises using a TORC cleaning system for areas of large aged paint, it’s a more advanced power wash that uses a swirling vortex of water and a fine granulate. Using a power washer for the painted surface or any other surface is highly eco-friendly. The reason is that it does not emit bad smells or chemicals. Its only function is to push off the objects and particles from the surface with the help of air pressure.

Required Material

Procedure

Before starting the procedure, ensure that your machine is easy or runs at 4GPM, and the washer can offer pressure of about 2000 to 3000 psi. In my experience, The reason is that low pressure is not enough to perform the job as it can’t pick up or clean away the paint quickly, and high pressure is not good as it can fade up the colors. Also, stand 10 miles away from the area that you want to clean where spray paint is applied. Now follow the steps I gave below:

1. Just start the procedure by following the instructions that are mentioned on the machine to remove spray paint from the concrete surface
2. Turn the sprayer on the spray paint washer machine and set the pressure to 2000 to 3000 psi
3. Now use side-by-sweeping motion just as you do to clean a floor with the help of a wiper or any other machine; hence, you can easily clean the area.
4. A large nozzle is recommended, and you can buy a washer with a small nozzle for the smaller areas. Also, ensure the nozzle angle while removing spray paint from the concrete is 40 degrees, 45 degrees, or around this range

Pros

• Affordable and requires less time
• Eco friendly

Cons

• You need some experience in using a pressure washer

Method 4: Using Angle Grinder

If you still ask the question of how to get spray paint off the concrete, I would recommend using an angle grinder. An angle grinder is a device that aims to remove unwanted particles from the concrete or any other surface with the help of push force. It works just like a sander.

You can even perform heavy projects using this grinder apart from the spray paint removal from concrete. It works on the principle of spinning a wheel to remove spray paint and other particles not only from concrete but from any surface.

Required Material

Procedure

1. Firstly, clean the area where you want to use a grinder with the help of smooth old cloth
2. Wear gloves, gear, and a safety jacket if possible. Other you can use any old but protective cloth from your home (This cloth should be made of plastic paper)
3. Now put a high spinning wheel on the grinder at the lower side where a specific space is made for it
4. Now align the angle grinder so that the wheel is towards the concrete but not its edges (Edges need to avoid from the surface because they can damage and cause break issues in the machine)
5. Please turn on the angle grinder and start using it on the machine. Remove all the spray paint particles from the concrete by scrubbing them after using the angler grinder with a wheel

An angle grinder works like a sander that scrubs the particles from the surface. So, ensure you are not implementing enough pressure to avoid the structure change issues in the concrete. I again remind you to wear safety clothes and goggles to avoid irritation and allergic reactions by scrubbing off the paint.

Pros

• Affordable to use
• Environmentally friendly
• Does not use any chemicals 

Cons

• It would help if you were experienced enough to implement this procedure
