Removing dried paint from pavers can be a tricky task, but there are several methods that can be effective. The best approach may depend on the type of paint and the extent of the damage. Some common suggestions include using a power washer, applying paint remover, or scrubbing with a wire brush and a solution such as soap and water, mineral spirits, acetone, or lacquer thinner. Before attempting any method, it is important to test it on a small area first to ensure it does not damage the pavers or alter their appearance.

What You'll Learn
Use a power washer
Using a power washer is an effective way to remove dried paint from pavers. However, it may not always be practical. If the pavers are set in sand, the force of the water will blow the sand away.
To use a power washer effectively, follow these steps:
- Begin by selecting a suitable power washer. For removing dried paint, a powerful model is required, such as a gas-powered washer that can develop at least 3,000 psi.
- Choose the right nozzle attachment. Avoid nozzles with very narrow spray patterns, as they can damage the pavers. Similarly, a spray pattern that is too wide will be ineffective.
- Keep the wand of the power washer at a low angle to protect the pavers and ensure a quicker process.
- Maintain a safe distance by keeping the nozzle at least 6 inches away from the paver surface to avoid gouging the pavers.
- If there is a garden nearby, spray away from it to prevent paint flecks from landing on the plants and soil.
- Wear protective gear, such as gloves and goggles, when handling chemicals or power washing to ensure your safety.
While power washing is a popular method, it may not be suitable for all situations. Some people believe that power washing will etch the surface and remove the cream from the pavers. Therefore, it is essential to exercise caution and consider other alternatives if power washing is not necessary.

Try a solvent
If your pavers have not been sealed, you can use a solvent to remove the paint from the surface. However, be aware that some of the paint may have been absorbed by the paver and will be impossible to remove. This is technically property damage.
If the pavers were sealed, a solvent like acetone or a painter's solvent will quickly remove the paint. You will have to reseal the paver afterward because the solvent will remove the sealer as well as the paint.
There are different solvents for different types of paint. If the paint is oil-based, you can use mineral spirits or lacquer thinner. For latex-based paint, isopropyl alcohol is another solvent you can use to dissolve it.
One method for removing paint from pavers is to drizzle xylene on the affected area, then blot it up with paper towels. Repeat this process until the paint is gone.
If you're using a solvent, it's recommended to wear a respirator, as the fumes can be bothersome.

Soak with vinegar
If you want to remove dried paint from pavers, one option is to soak the area with vinegar. Here is a detailed guide on how to do this:
First, pour vinegar evenly across the affected pavers. Make sure to cover the entire painted area and soak the gaps between the pavers as well. It is recommended to use white vinegar and let it sit for about an hour. During this time, the vinegar will start to break down the paint, making it easier to remove.
After the vinegar has soaked, spray the surface with a mixture of soap and water. This step will help to further loosen the paint and prepare it for scrubbing. Use a nylon bristle brush to gently scrub the area, being careful not to damage the pavers.
Once you have finished scrubbing, rinse the area with warm water to remove any remaining vinegar, soap, and paint residue. Then, let the pavers dry.
If the paint is particularly stubborn, you may need to repeat the process or try a different method. Additionally, if you are concerned about the vinegar causing surface etching on the stone, you can test it on a small area first or opt for a different cleaning solution.
While vinegar is a natural and effective way to remove paint from pavers, it may not work for all types of paint. For example, if the paint is oil-based, you may need to use a solvent such as mineral spirits or lacquer thinner.
Always exercise caution when working with any chemicals, and follow the manufacturer's instructions and safety guidelines.

Scrub with a wire brush
If you want to remove dried paint from pavers, one option is to scrub it off with a wire brush. This method can be effective, especially when combined with other treatments, but it may damage the paver.
Before you start scrubbing, it's a good idea to treat the paint to make it easier to remove. One option is to soak the pavers with soap and water or a solvent. For example, you could use white distilled vinegar, which will help to soften the paint, or a stronger solvent like mineral spirits or lacquer thinner. If the paint is latex-based, isopropyl alcohol is another solvent you can use to dissolve it. You can also strengthen your soap and water solution by adding trisodium phosphate (TSP) or a TSP substitute (use about half a cup per gallon of water). Be sure to wear gloves and goggles if you're using TSP, as it's caustic.
Once you've treated the paint, you can start scrubbing with a wire brush. This will reach into the pores of the concrete or stone where the paint has settled and scrape it away. Be careful not to scrub too aggressively, as you may damage the paver or cause discolouration.
Even with a wire brush, you may have problems removing dried paint, especially if it's an oil-based paint. In that case, you may need to resort to stronger solvents or a power washer. If you use a power washer, keep the wand at a low angle and at least 6 inches away from the surface to avoid damaging the pavers.

Use a paint remover
Using a paint remover is an effective way to remove dried paint from pavers. Paint removers are readily available at most hardscape suppliers and can effectively eliminate paint stains. Before applying any paint remover, it is crucial to read and follow the manufacturer's instructions to ensure proper usage and safety.
When using a paint remover, start by testing it on a small portion of the stain to gauge its effectiveness and check for any adverse reactions on the pavers. If the paint remover works as intended, proceed to apply it to the entire stain, following the manufacturer's instructions. Keep in mind that paint removers can dissolve sealants, so it is essential to use them in dry conditions and take the necessary precautions.
For oil-based paints, you may need to use a solvent such as mineral spirits or lacquer thinner, as soap or TSP (trisodium phosphate) and water may not be sufficient for emulsification. On the other hand, if the paint is latex-based, isopropyl alcohol can be used as a solvent to dissolve it effectively. Always wear a respirator if the fumes become bothersome, even when working outdoors.
Additionally, consider using a wire brush as an abrasive tool to reach the pores of the concrete or stone where the paint has settled. Soaking the pavers with soap, water, or a solvent before scrubbing can make the process easier and enhance the removal of dried paint. Remember to keep a safe distance between the nozzle and the paver's surface when using a power washer to avoid damaging the pavers.
By following these steps and using a paint remover, you can effectively remove dried paint from pavers. Just make sure to test the product on a small area first, follow safety instructions, and choose the appropriate solvent and tools for the type of paint you are dealing with.
