Since it is permeable, the concrete may easily absorb the paint. Paint may quickly soak through a concrete surface, going several millimeters deep. As a result, determining how to remove paint off concrete may be difficult, but it is possible.

You may have thrown up your hands in despair after accidentally spilling or splattering paint onto a new concrete floor, patio, or another surface, thinking the area would stay there forever.

Even though a paint spill on concrete may look terrible, there’s no need to panic. Most paints can be effectively stripped out with little elbow grease and time. This article will assist you in removing paint from the concrete, whether it is a recent spill or a color baking in the sun for years.

How to Remove Paint From Concrete Flooring

You can use chemicals to strip paint from your concrete floors, or you can visit your neighborhood hardware store and rent the same machines that the pros use. Choose the method for removing paint from concrete that you feel will be the most effective.

1. Deep-clean the concrete surface, then let it dry

The cleaning process will go more smoothly if you first sweep or vacuum the area to remove any large pieces of dirt or trash. Scrub the surface using a wide-wire brush and a solution of warm water and soap or warm water and a trisodium phosphate (TSP) substitute.

Wear protective clothing, including long sleeves, goggles, and gloves, if you must use TSP instead of a safer alternative. Wait at least three hours for the solution to dry.

2. Using Paint Strippers

An oil-based paint stripper should be used on oil-based paint. Use a paint remover that is either water- or plant-based to remove latex acrylic paint. Choose an oil-based remover if you are unsure about the sort of paint used on the concrete.

Use an old paintbrush to apply a thick coat of stripper as directed on the bottle. Let it run for the advised amount of time, which is usually several hours. Paint on the concrete should start peeling away from the surface.

3. Using a Power Washer

Green paint removers work well but leave a sticky residue that might be difficult to clean off. Power washing is an excellent alternative to cleaning up paint spills on outside concrete.

Power washers with a minimum of 3000 psi of pressure and 4 gallons per minute of flow rate will produce the best results. Instead of buying an industrial power washer if you don’t want to, try borrowing or renting one. A 3rd choice is to hand over the task to someone else.

4. Use a Soda Blasting

Sodium bicarbonate is used to give the concrete a good smack rather than pouring a can of soda over it. Power washing also requires specific tools.in this case, an industrial soda blaster. Usually, you can rent these things from hardware shops, which costs from $100 – $1,500. Hardware stores will also carry the particular sodium bicarbonate you’ll need for the job.

5. Use Sandblasting

Another effective tool for stripping paint from concrete is the lowly sandblaster. You’ll need the right tools once again. Costing roughly $1,000 on average, industrial sandblasters may be rented from most hardware stores, along with the crystalline silica solution required for use.

6. Use a DIY Mixture

You may make your own paint-removing solution. While many effective formulas exist, many also share similar elements like clay and kitty litter, which are both very absorbent. You’ll find an easy recipe and instructions below.

  1. To make your own, mix together one cup of finely crushed clay, one cup of cat litter, and a splash (about half a cup) of professional paint thinner (vinegar will do in a pinch).
  2. Prepare a thick paste by mixing the components together, wearing rubber gloves for safety.
  3. Spread the paste thickly over the damaged cement.
  4. Soak it for at least two hours.
  5. Use a wire scrub brush or paint scraper to remove the loose paint.


It’s a headache to have to strip old paint from concrete. You can make that concrete surface look as good as new in no time if you follow the procedure outlined above and use the appropriate equipment.
