One of the least expensive and least-maintenance flooring options is concrete. If you accidentally get new paint on concrete, it's simple to remove: just wet the area, then scrub the paint off with a stiff-bristled brush and detergent. However, removing dried paint can be frustrating due to concrete's propensity to absorb the paint. Even though it might take some time, it's not impossible to remove dried paint. Discover the step-by-step process for removing paint from concrete.

Clean the concrete surface completely and let it dry.
The first step in removing paint from concrete is to clean the concrete's surface thoroughly. Make a soap and water solution or, even better, dilute trisodium phosphate (TSP)—in which case, wear gloves. While waiting, sweep or wipe the concrete to eliminate any loose dirt, dust, or other debris. Use a long-handled brush to scrub the soapy water or TSP into the concrete. After that, rinse the area and dry the surface for one to three hours.
Scrape peeled or chipped areas and apply paint stripper.
Take a putty knife to remove any paint that has already started to peel or chip. After that, get ready to use the chemical paint remover. Use one made specifically for the paint you're attempting to remove. Or, apply an oil-based paint stripper to a surface painted with oil-based paint. Uncertain of the paint's type on the concrete. The best choice is to use an oil-based paint stripper if you're unsure.
Remove paint stripper residue.
If you're working on a compact concrete patch, you can get by with a wire scrub brush or a paint scraper for this project stage. Renting a pressure washer from your neighborhood home center will help make things much more manageable on a larger surface.
Nonchemical Solutions
Although there are other options, they are all more labor-intensive than using a paint stripper. For instance, you could use an orbital sander on a modestly sized concrete surface. A floor buffer can also complete the task on a larger scale. A dust mask or respirator is necessary to remove paint from concrete because all of the methods above produce fine particles, especially if you're working indoors.
Remove Paint From Concrete Floor with Vinegar
Vinegar is a cheap all-purpose cleaner that is a natural paint remover and a remedy for oil stains on driveway surfaces. Both the environment and your household are safe. To remove paint from concrete without using a hazardous chemical paint stripper, use vinegar.
Remove Paint from Concrete By Using Paint Thinner
Use a commercial paint thinner, such as spray paint or oil-based paint, if the paint is particularly difficult to remove. First, patch test a small, concealed area to ensure it won't damage the concrete surface.
When handling paint thinner, wear safety equipment like safety glasses, gloves, and a respirator mask. Wearing protective clothing is also advantageous because it keeps the chemicals off your skin.
DAWN SOAP AND HOT WATER
After the vinegar experiment, we shifted to using hot water and Dawn soap. Dawn is so effective at so many things that we decided to try it. We scrubbed the floor with a mixture of hot water and Dawn soap. We then tried scraping the stains off.
Paint removal using a grinder
Grinding off the paint with a walk-behind or handheld concrete grinder is a chemical-free substitute for using paint strippers to remove paint from concrete floors. These tools are excellent for cleaning and lightly abrading concrete floor surfaces and removing thin paints and coatings.
Many home improvement stores and equipment rental businesses rent out portable and small walk-behind concrete floor grinders and appropriate grinding discs.
