Removing paint from stone can seem like a daunting task, especially if you want to bring back its natural beauty. Whether it’s a stone fireplace, an outdoor wall, a patio, or even a decorative stone table, choosing the right method makes all the difference. Some techniques work quickly and powerfully, while others require a gentler touch to avoid damaging the stone. In this guide, we’ll walk you through several effective ways to remove paint from stone, from chemical removers to sanding tools, so you can pick the best approach for your project.
Paint Removal From Stone
Paint stains on stone can really take away from its natural charm. Whether it’s an aged fireplace, a stone wall, or a walkway outside, getting rid of paint requires patience and the right approach. Luckily, there are several tried-and-true methods to restore your stone to its original look. Here, we’ll cover five effective techniques, along with practical tips to make the process easier and more efficient.
1-Paint Remover (Chemical Strippers)
One of the easiest ways to remove paint from stone is by using a paint remover. These products are designed to break down paint, making it much simpler to scrub or wash away.
Start by protecting yourself—put on gloves, safety goggles, and a mask to stay safe from the chemicals. Then, use a brush to spread the paint remover evenly over the stone. Make sure every painted spot is covered so the remover can do its job.
Let it sit for the time suggested on the label, usually around 15 to 30 minutes, so the paint softens. Once it starts to lift, gently scrub it off with a stiff brush or scraper. Finish by rinsing the stone thoroughly with water to wash away any leftover residue, leaving the surface clean and ready for the next step.
Pro Tip: Always test the paint remover on a small, hidden spot first. Some harsh removers can slightly discolor certain types of stone like marble or limestone.
2-Sandblasting
Sandblasting is a highly effective method, especially for outdoor stone surfaces like walls, patios, or fountains. It works by using high-pressure air mixed with sand or other abrasives to strip away paint quickly.
One of the main benefits of sandblasting is how fast it can remove multiple layers of old paint. It’s also ideal for rough or textured stones, where paint often settles deep into cracks and is hard to reach with brushes or scrapers.
That said, there are some important things to keep in mind. Sandblasting requires special equipment and a bit of know-how to do safely. If not done properly, it can scratch or wear down the stone unevenly. Because of this, it’s usually best to hire a professional to make sure the job is done right.
“Good to know: After sandblasting, you might need to seal the stone to protect it from future paint stains or moisture damage.”
3-Acetone
Acetone is a strong solvent that works best for small paint spots or detailed areas, like carved stone designs. It’s perfect when you need to be precise without harming the surrounding stone.
To use it, dampen a clean cloth with acetone and gently rub the painted stone area until the paint starts to lift.
For tougher spots, let the acetone sit for a few minutes before scrubbing. Once the paint loosens, rinse the area thoroughly with water to wash away any remaining residue and restore the stone’s natural look.
“Safety reminder: Acetone is flammable and has strong fumes. Make sure you work in a well-ventilated space and keep it away from open flames.”
4-Cellulosic Thinner (Paint Thinner)
A cellulosic thinner, also called lacquer thinner, is another strong option for removing paint. It’s especially effective on stubborn, oil-based paints that won’t come off with basic cleaning.
To use it, soak a cloth or sponge in the thinner and apply it directly to the painted stone, making sure the surface is fully covered so the paint can soften. Then, scrub the area with a wire brush or stiff-bristle brush to lift the loosened paint. Once the paint starts coming off, wipe it away and rinse the stone thoroughly with plenty of water to remove any leftover thinner and paint residue, leaving the stone clean and ready for use. “For more information, read the article “Can Thinner Remove Paint?”.”
“Caution: These thinners are very strong and can be harsh on delicate stones. Always test a small section before applying it to the entire area. Also, wear protective gear to avoid skin or eye irritation.”
5-Sanding Machine (Mechanical Sanding)
If you prefer a more hands-on approach, using a sanding machine or angle grinder can be very effective on flat stone surfaces. This method works particularly well for large areas or thick, stubborn paint that chemical removers can’t easily handle.
It’s perfect for patios, steps, or big stone tiles. To use it safely, pick the right sanding disc or attachment meant for stone and work slowly and evenly to avoid scratching or gouging the surface. Be sure to wear protective goggles and a dust mask, as this process creates a lot of fine dust.
“Note: After sanding, thoroughly clean the stone to remove dust particles before applying any sealant or protective coating.”

A gel-based paint remover designed for masonry surfaces is usually the best option. It sticks to vertical surfaces and penetrates deep into textured stone.
How to Remove Paint From a Stone Table?
Start with a gentle method like acetone or a paint remover. Avoid sandblasting or heavy sanding, as they can scratch the table’s surface.
How to Get Paint Off of a Stone Fireplace?
Use a chemical paint remover and a stiff brush. For detailed areas, a toothbrush can help reach small crevices. Be sure to ventilate the room well while working.
How to Remove Spray Paint From Stone?
Acetone or lacquer thinner works well for spray paint. If the area is large, you can also use a paint remover and scrub with a wire brush.
How Do You Remove Paint From a Stone Foundation?
Sandblasting or a heavy-duty paint remover is usually the most effective for foundations. Always clean the stone thoroughly afterward to prevent moisture damage.
How to Remove Acrylic Paint From Stone?
Acrylic paint is water-based, so start with warm soapy water and a scrub brush. If that doesn’t work, try acetone or a mild paint remover.
By picking the method that best suits your type of stone and the size of your project, you can remove paint safely without harming the stone’s natural look. Whether it’s just a few spots or an entire stone wall, using the right tools and a bit of patience will make the process much easier. “You might also be interested in: How to paint stone.”
