Join us as we traverse the realms of history, craftsmanship, and restoration, guiding you step-by-step on a journey towards embracing the pure essence of these enchanting relics.
1. Wash The Paint off
If the stone window sill has latex or acrylic paint, use warm water to remove it. Water-based finishes are washable and come off if exposed to water. The warm water and soap will break down the paint particles, making it easier for you to scrape it off.
For this method, you’ll need some supplies:
- Dish soap or laundry detergent
- A scrubbing brush
- A bucket of water
- Clean rags
Here’s how to do it:
- Wipe the window sill with a clean rag to remove debris and dust.
- Pour detergent (or dish soap) into a bowl filled with warm water. Mix to create lather.
- Dip a scrubbing brush in the mixture, and scrub the surface. As you scrub, you should see the paint coming off.
- Rinse the affected spot with water and let the surface dry. When the surface is dry, inspect it to see if all the paint is off.
- If there are leftovers on the surface, scrub again.
- Wash the surface.
Pros
- Dish soap doesn’t etch or damage the stone material.
- It is a cheap method. Usually, all the supplies needed can be found in your home.
- It works to strip off acrylic and latex.
Cons
- The method is time-consuming. You’ll have to scrub for a long time to remove large finishes.
- This method won’t remove oil paints and sealants.
- The method is labor-intensive and can wear you out quickly.
Tip: While scrubbing, if you notice that the finish isn’t coming off, it means that this method will not work. Luckily, we still have a few methods to try out.
2. Scrape The Paint Off
You can scrape off all types of paint, but scraping works best for old flaking finishes. To scrape, use a scraper.
For this method, you need the following tools:
- A paint scraper (a trowel or metallic putty knife will work)
- A soft brush.
- A mild solvent (white spirit).
Here’s how to do it:
1. Scrape the Finish Off
- Position the tip of the scraper underneath the bottom layer of the finish.
- Push the scraper and lift to remove the paint.
- Repeat this until most of the finish is off.
2. Apply a Mild Solvent to the Affected Spot
The downside of using a scraper is that you won’t be able to remove all the paint. There will still be small stains on the stone material. To remove the stains left, use a solvent. White spirits or rubbing alcohol are great choices.
Pros
- The method is cheap. You wouldn’t need to buy any costly item or solvent.
- It works on all paint types; oil or water-based.
Cons
- This method can damage the stone material
- The method is time-consuming and requires a lot of effort.
- This method doesn’t strip all the paint.
Tip: Use a plastic scraper if you don’t want to scratch the surface.
3. Using Chemical-Based Paint Removers
Using chemical-based paint removers is an effective way to strip finishes and stains from the windows stone. It works with all types of finishes, including sealers.
You have to apply the chemical-based stripping compound over the finish, wait 15 minutes, and then scrape the stripping compound (the finish will come off too).
The way this method works is that the stripping compound penetrates the finish and breaks the bond between particles, the compound also dries inside the coating. So, when you scrape the stripping compound, you will remove the finish too.
For this method, you’ll need:
- A chemical-based paint remover
- A nose mask
- A pair of goggles
- A pair of gloves
- Rags
- A paintbrush (optional)

2. Unleash the Natural Beauty: Step-by-Step Guide to Removing Paint from Stone Lintels
Should we remove paint from stonework?
Paint can stop stone from breathing, causing damage to stone, however:
- stone may have been painted to cover old repairs – removing paint may leave a poor appearance
- paint may stop rain entering very porous stone
- painting may be the traditional style in your area – removing paint may require planning consent
- paint removal from listed buildings or in conservation areas requires consent
- chemical paint removers can cause health risks and lead-based paint is a hazardous waste
- paint may be exceedingly hard to remove from porous stone types, especially where thickly applied historic paints have been used
Removing paint will always cause some damage to the stone, so carry out a test patch first.
If your building is harled (rendered), then it is important to keep the harling painted. This will cover hairline cracks which allow moisture to get behind the harling, causing it to break off. Use specialist breathable paints available from lime suppliers and others sources. Some types of harling are self-coloured and not painted.
Paint removal methods
Always start with the least aggressive method. Use a suitably qualified professional to undertake work for you.

These are the methods you can use, starting from the least aggressive and working to the most aggressive:
- weathering: let nature take its course and allow the paint to deteriorate naturally – however, the intermediate look may not be acceptable
- water washing: gentle sponging or scrubbing with a soft bristle brush may be effective for emulsions, limewash, and other very old, friable paints
- steam stripping: superheated low-pressure steam stripping for water-thinned paints, such as emulsions, can clean without saturating the surface of the stone
- solvent (non-caustic) chemical removers: a water-soluble remover should be considered before use of a methylene chloride-based solvent – they are best suited for the removal of oil or latex-based paints, but may not be as effective with others
- alkaline (caustic) chemical removers e.g. caustic soda or potash: these can be particularly damaging to stonework and can be absorbed by porous stonework, where the damaging effects can continue long after – avoid unless no immediate or ongoing damage to the stonework can be demonstrated – chemical removers should be thoroughly washed from the stone afterwards to avoid leaving any residue
- manual abrasive: scraping, sanding, wire bristle brushing or other aggressive manual cleaning can cause significant damage to stone
- mechanical abrasive: high-pressure water cleaning, sand or grit-blasting can also cause significant damage to stonework, making it more vulnerable to weathering and result in loss of architectural detail
Whatever the method, it is often advisable to allow particularly stubborn paint to remain and weather naturally to avoid damage to stonework or pointing. Such damage can lead to a need for more expensive repairs or repointing.
