How To Remove Acrylic Paint From Concrete

How To Remove Acrylic Paint From Concrete

The dilemma of using acrylic paint on concrete is a common predicament artists, homeowners, and builders face.

From accidental splashes during a creative project to unwanted graffiti, acrylic paint can make it onto your concrete surfaces.

Why does it matter? With its durability and vivid colors, acrylic paint can be an eyesore and a nuisance on an otherwise clean, uniform concrete surface.

Moreover, it creates a layer that can hinder the adhesion of any new paint or sealants you may want to apply.

Knowing how to remove acrylic paint from concrete efficiently and safely is crucial. Let’s delve in.

Preparing for Paint Removal

How To Remove Acrylic Paint From Concrete

Before you begin

Step 1: Assess the Paint Condition

Before you start the removal process, it’s crucial to assess the condition of the paint. Is it fresh and wet? Or has it dried and hardened over time?

Excess wet paint usually calls for a simple wipe-down and clean-up, while dried paint will need more effort to scrape and dissolve.

Step 2: Gather the Necessary Tools and Materials

Once you’ve assessed the paint condition, it’s time to gather the necessary tools and materials. Here’s a handy checklist to guide you:

  1. Protective Gear: Safety should always be a priority. Ensure you have a pair of gloves, safety goggles, and a mask to protect yourself from harmful chemicals or particles.
  2. Scrapers and Tools: Depending on the condition of the paint, you may need scrapers, paintbrushes, or blunt knives to scrape off the dried paint.
  3. Cleaning Agents: Several cleaning agents can aid in paint removal. Common household items like vinegar and dish soap can be surprisingly effective. For tougher jobs, paint thinners or acetone might be necessary.
  4. Absorbent Materials: Newspapers, rags, towels, and cloths can absorb wet paint or clean up after a paint removal session.
  5. Buckets or Containers: You’ll need somewhere to mix your cleaning solutions and discard any scraped-off paint. A few buckets or containers do the trick.
  6. Brushes: A good scrubbing brush or a wire brush can come in handy, especially for getting into the nooks and crannies of a textured concrete surface.

Removing Wet Paint Splatters from Concrete

Step 1: Wipe off wet paint

Your first instinct might be to wipe the paint away immediately. But, this can spread the paint, creating a larger problem.

Instead, use an absorbent material like rags, towels, or old newspapers to blot the excess paint gently. Remember, the key is to dab, not to smear or spread.

Step 2: Scrub with a soapy solution

Once you’ve blotted away as much wet paint as possible, it’s time to prepare a warm or hot water and soap/detergent solution.

The warmth of the water combined with the soap helps break down the acrylic paint’s bond to the concrete.

Take a scrubbing brush and soak it in your soapy solution, then start scrubbing at the remaining paint.

Pay particular attention to any stubborn spots or areas where the paint has begun to dry.

Step 3: Rinse and dry

After you’ve loosened and removed the paint with your soapy solution, rinse the concrete with clean water.

It will help wash away any remaining soap or loosened paint particles. Once you’ve rinsed the area, let it dry completely.

Drying ensures that no water or soap is left on the surface, which could interfere with any further steps or future painting you may want to do.

Removing Dried Acrylic Paint from Concrete

How To Remove Acrylic Paint From Concrete

Step 1: Scrape off loose paint

To remove dried acrylic paint from concrete, use a paint scraper, a blunt knife, or even a razor blade to carefully scrape off as much of the dried paint as possible.

Apply gentle pressure to avoid scratching or damaging the concrete. Remember, the goal is to remove the paint, not etch new designs on the surface.

Step 2: Apply paint thinner or remover

Once you’ve scraped off the loose paint, you may still see stubborn spots or layers of paint. For these, you’ll need the help of a paint thinner or paint remover.

Choose a product suitable for acrylic paint and follow the manufacturer’s instructions.

Apply the paint thinner or remover solution to the remaining dried paint and allow it to sit for the recommended time.

Step 3: Remove softened paint

After the paint thinner or remover has done its job, use a scrubbing brush to remove the now-softened paint.

Warm or hot water can help in this removal process, dissolving the paint further and aiding in scrubbing it away.

Step 4: Repeat and rinse

Stubborn paint might need you to repeat the steps. Keep applying the paint remover, scrubbing, and rinsing until you remove all the paint.

After your final rinse, allow the concrete to dry completely to ensure you have a clean, dry surface ready for further treatment or to appreciate in its unpainted glory.

Methods to Remove Acrylic Paint from Concrete Floor

Method 1: Vinegar and dish soap remedy

The acid in the vinegar breaks down the paint, while the soap helps to lift it off the concrete surface. Here’s how to do it:

Step 1: Mix the Solution: Mix equal parts of vinegar and dish soap in a bucket or container.

The exact amount you’ll need will depend on the size of the paint spill, but a good rule of thumb is to make enough so that the entire paint stain can be thoroughly covered with the solution.

Step 2: Apply the Solution: Pour or dab the vinegar and dish soap solution onto the paint stain. Cover all of the paint with the solution to ensure effective removal.

Work the solution into the paint using a scrub brush, scrubbing vigorously to help loosen and lift the paint particles.

Step 3: Rinse and Dry: Once you’ve scrubbed the area, rinse it thoroughly with water to remove the soap, vinegar, and any loosened paint.

Lastly, allow the area to dry completely to give you a better view of your handiwork, and a dry surface is also better for further treatment if necessary.

Method 2: Nail polish remover

Step 1: Choose a Strong Nail Polish Remover: No nail polish remover will do when dealing with dried paint.

Opt for a nail polish remover with a high concentration of acetone.

It will give you the extra strength needed to dissolve stubborn acrylic paint.

Step 2: Apply and Scrub: Wearing gloves, apply a generous amount of the nail polish remover directly to the paint stain. 

Use a scrub brush to work the remover into the paint, applying pressure to help lift and remove the paint from the concrete.

Step 3: Rinse and Dry: After scrubbing, rinse the area with water to remove any residue from the nail polish remover and the loosened paint particles.

Remember to let the area dry thoroughly to assess the success of your paint removal efforts and decide if a second round is necessary.

Method 3: Paint thinner with 80 grit sandpaper

Step 1: Prepare Your Materials: For this method, you must paint thinner and 80-grit sandpaper.

The paint thinner will help to dissolve the paint, while the sandpaper will scrape away the softened paint particles.

Step 2: Apply Paint Thinner and Sand: Wearing your safety gloves and goggles, apply thinner to the dried paint. Let it sit for a few minutes to start softening the paint.

After allowing the thinner to work, use the 80-grit sandpaper to sand away the paint.

Be sure to sand evenly to avoid creating divots or uneven surfaces in the concrete.

Step 3: Clean and Dry: Once you’ve sanded the area, clean it with warm soapy water to remove any residual paint or paint thinner.

Allow the area to dry completely to see the results of your efforts. If any paint remains, you may need to repeat the process until all the paint is removed.

Method 4: Paint thinner and 80-grit sandpaper

Step 1: Get Your Materials Ready: First off, equip yourself with paint thinner and 80-grit sandpaper.

The rough texture of the sandpaper works well with the paint-dissolving power of the paint thinner, making a great team against the hardened acrylic paint.

Step 2: Sand the Paint: Don your protective gear and apply a generous layer of paint thinner on the paint stain. Let it sit for a few minutes to break down the paint.

Once the paint has softened, spray it off with your 80-grit sandpaper. Remember to be gentle; you want to remove the paint, not damage the concrete underneath.

Step 3: Clean and Dry: After you’ve sanded off as much paint as you can, clean the area with a damp cloth or mop to remove paint debris and any leftover thinner.

Let the area air dry thoroughly to see if any paint remains. If necessary, repeat the process until you achieve a clean, paint-free concrete floor.

Method 5: Harnessing the power of paint thinner and 80-grit sandpaper

For those stubborn, hard-to-remove acrylic paint stains, using a combination of paint thinner and 80-grit sandpaper can do wonders.

This duo will help you get back your clean, spotless concrete floor. Here’s your game plan:

Step 1: Gather Your Materials: First, make sure you have paint thinner and 80-grit sandpaper.

This combination is effective because the paint thinner breaks down the paint, making it easier for the rough texture of the sandpaper to scrape it off.

Step 2: Sand the Stain Away: Pour some thinner paint onto the dried paint and let it work for a few minutes to soften it, preparing it for removal.

Once the paint starts to loosen, grab your sandpaper and gently sand the area, ensuring not to damage the underlying concrete.

Step 3: Clean Up and Dry: After all the scrubbing and sanding, it’s time to clean up. Use a damp cloth or a mop to remove any residual paint or paint thinner.

Allow the area to air dry fully to help you see if any paint is left. If there is, don’t hesitate to repeat the process until your concrete floor is free from paint.

Method 6: Paint Stripper

Step 1: Choose Your Paint Stripper: There are various types of paint strippers available in the market. Choose one that’s specifically designed for acrylic paint.

Check the manufacturer’s instructions and warnings, as some may contain strong chemicals that must be handled cautiously.

Step 2: Prepare the Area: Before you start, it’s crucial to prepare the area by moving any furniture, covering nearby plants or objects with plastic sheets to protect them, and ensuring adequate ventilation if working indoors.

Step 3: Apply the Paint Stripper: Once your area is ready, don your safety gear, and apply the paint stripper onto the paint-stained concrete.

Follow the product instructions about how long you should let the stripper sit. This waiting period is key to letting the stripper penetrate and break down the paint.

Step 4: Scrape and Clean: After the paint stripper has done its job, it’s time to scrape off the paint. Using a scraper, start removing the loosened paint.

Be gentle to prevent any damage to the concrete. After scraping, rinse the area thoroughly with water, ensuring all residues of the stripper are washed away.

DIY Alternatives

If you’re in a DIY mood, create a paint stripper home using common household ingredients like vinegar, baking soda, or dish soap.

However, remember these might not be as effective as commercial paint strippers and require more effort and time.

Is paint stripper toxic? How can I protect myself while using it?

Method 7: Pressure washer and degreaser cleaner

Step 2: Off Grind the Paint: Attach the wheel to the drill and apply it to the paint.

Step 3: Clean Up: Once you’ve removed the paint, clean the area to help remove any leftover debris. Once the area is cleaned, allow it to dry before using it.

Method 10: Buffer

A buffer machine is an excellent option when dealing with larger paint areas on concrete. Here’s how to use it:

Step 1: Gather Your Tools: This method needs a buffer machine. You can rent one from a hardware store if you don’t have one.

Step 3: Clean Up: After you’ve removed the paint, clean the area to get rid of any residue left behind.

Once the area is clean, let it dry to prepare the concrete for further treatment or use.

Method 11: Acetone

Step 1: Apply Acetone: Pour a small amount of acetone directly onto the paint. Remember to protect your skin and eyes, as acetone can be harmful.

Step 2: Scrub: Use a scrubbing brush to scrub the area where you’ve applied the acetone. The acetone should help loosen the paint, making scrubbing easier.

Method 15: Power washing

Step 1: Set Up Your Power Washer: Connect your power washer to a water source. Ensure the washer is in a suitable setting for concrete.

Step 2: Wash Away the Paint: With the power washer ready, aim it at the paint. The high-pressure water will peel away the paint.

  • Cover surrounding areas with plastic or protective sheets.
  • Apply masking tape or painter’s tape to protect specific areas.

Does acrylic paint wash off concrete?

No, acrylic paint does not wash off concrete easily once it has dried. It strongly bonds the porous surface, making simple washing ineffective. Additional methods like scraping, solvents, or pressure washing are necessary for effective removal.

What grit sandpaper to remove paint from concrete?

For paint removal from concrete using sandpaper, start with a medium to coarse grit, such as 80 or 100. These grit levels provide sufficient abrasiveness to remove the paint without causing excessive damage. Adjust the grit size based on the paint thickness and condition.

Will vinegar remove paint from concrete?

Vinegar alone is not enough to remove paint stains from concrete. Although vinegar can be effective against certain stains, its acidic nature has a limited impact on dried or stubborn paint. Combine vinegar with scraping, solvents, or pressure washing to remove paint from concrete better.

Will the same paint stripper remove paint from wood floor?

Yes, the same paint stripper that removes paint from other surfaces can also remove paint from wood. Paint strippers are formulated to dissolve and soften paint, allowing it to be scraped or wiped away, making them effective for removing paint from various materials, including wood surfaces. (Here’s a detailed guide on how to get dried acrylic paint off wood floor).


Removing acrylic paint from concrete can be a challenging task. However, with the right methods and tools, it is achievable.

Whether the paint is wet or dried, there are various techniques available. These include scraping, using solvents, or employing mechanical devices.

Prioritizing safety by wearing protective gear and taking precautions with chemicals is essential. 

Following the recommended steps and being patient can successfully restore your concrete surfaces.
