Every spring we get the same call from Winnetka, Wilmette, and Northbrook: “We want to lighten the brick.” Then the homeowner says whitewash, limewash, and paint in the same sentence as if they were one thing. They are three different finishes with three different lifespans, and the right choice depends on the brick you have, the look you want, and how you feel about it being permanent. Here is how we explain it on the walk-through.
The Short Version
- Limewash is a mineral coating that soaks into the brick and calcifies. Soft, chalky, slightly uneven, and it ages into a patina. The most breathable option and the most forgiving on old brick. Partly reversible in the first few days, then permanent in a weathered way.
- Whitewash today usually means watered-down paint brushed on and wiped back so brick shows through. Semi-transparent, rustic, quick. Less breathable than limewash because it is still paint, and it is permanent.
- Painted brick is an opaque coat of masonry paint. Uniform, crisp, and the look most people picture when they say “white brick house.” Permanent, and it needs a maintenance coat every ten to fifteen years.
- Mineral stain is the fourth option nobody mentions: a translucent silicate stain that shifts the brick color without sealing it. Great for toning down orange brick or matching an addition. Permanent and breathable.
Limewash: The Old-World Finish
Limewash is slaked lime and water, sometimes with natural pigment. Brushed onto bare, porous brick it reacts with carbon dioxide and turns back into limestone inside the surface of the brick, so there is no film to peel. It is the finish on centuries-old farmhouses in Europe and on a growing number of North Shore homes that want the soft, cloudy look rather than a flat painted one.
What to know before you choose it:
- It only bonds to unsealed, unpainted masonry. Previously painted brick cannot be limewashed.
- Coverage is intentionally uneven and gets more weathered over time. If you want perfectly uniform white, this is the wrong product.
- Because it is mineral and vapor-open, it handles Chicago freeze-thaw better than any paint. Moisture in the wall leaves as vapor instead of pushing a film off.
- Within the first day or two you can hose some of it back to expose more brick. After it cures, it is there for good, though it wears to a lighter patina rather than peeling.
- It wants a touch-up coat roughly every five to seven years on exposed walls, which is cheap and fast because there is no scraping.
Whitewash: Thinned Paint, Wiped Back
The word gets used for two things. Traditional whitewash was lime-based and is really just limewash. The modern version is a quality masonry or exterior latex paint diluted with water, brushed on in sections, then wiped with a rag so the brick color bleeds through. It gives a rustic, semi-transparent look that lands between bare brick and paint.
- It is faster and cheaper than limewash to apply and works on more surfaces, including some previously sealed brick with the right primer.
- It is still paint, so it forms a thin film. On a dry, well-detailed wall that is fine. On a wall with water problems it can flake in patches, and the patchy look is harder to touch up than solid paint.
- The amount of wipe-back controls the look. We always do a sample panel on the least visible wall and let the homeowner choose how much brick shows.
Painted Brick: Uniform and Permanent
Solid paint gives the cleanest, most modern result. It hides mismatched brick, patched areas, and stains completely, and it lets you pick any color, from warm white to charcoal. The trade-offs are that it seals the surface, which makes product choice critical in our climate, and that it is a maintenance item from then on.
- Use a breathable 100 percent acrylic masonry paint or a mineral silicate paint over an alkali-resistant masonry primer. Never an elastomeric or a waterproofing sealer on freeze-thaw brick.
- Expect ten to fifteen years before a maintenance coat, and expect the second repaint to involve more prep than the first.
- Stripping paint off brick later is slow, expensive, and rarely leaves the brick looking good. Decide once.

Mineral Stain: Change the Color, Keep the Brick
Silicate masonry stains penetrate and bond chemically, so they shift the color without a film. They are translucent, which means the texture and variation of the brick stay visible. We reach for stain when an addition’s brick never matched the original house, when 1970s orange brick needs to calm down, or when a homeowner wants a lighter tone but not an opaque wall. It is breathable, permanent, and needs no maintenance coat.
Side by Side
| Finish | Look | Breathable | Lifespan | Works on painted brick | Reversible |
|---|---|---|---|---|---|
| Limewash | Soft, cloudy, uneven, ages to a patina | Yes, fully | Touch up every 5 to 7 years | No | Partly, in the first days |
| Whitewash (thinned paint) | Semi-transparent, rustic | Partly | Varies, 5 to 10 years before patching | Sometimes, with primer | No |
| Painted brick | Opaque, uniform, any color | Only with breathable masonry paint | 10 to 15 years per coat | Yes | No |
| Mineral stain | Translucent color shift | Yes, fully | Permanent | No | No |
Which One for Which House
- 1920s and 30s Tudors and cottages in Winnetka, Kenilworth, Glencoe, and Evanston usually have softer, more porous brick. Limewash or mineral stain respects that brick; solid paint can trap water in it. We lean limewash.
- Mid-century ranches and split-levels in Northbrook, Glenview, Deerfield, and Skokie have dense, hard-fired brick, often in an orange or variegated tone the owner has stopped loving. Paint or stain both work well here; paint if you want a clean modern white, stain if you want to keep the texture.
- Mismatched additions anywhere: stain first, paint if the mismatch is too wide.
- Brick that is already painted: the choice is made. A proper repaint with breathable masonry paint is the only good option.
- Historic districts: check with the village before any of these. Limewash and stain are usually the easiest to get approved because they do not seal the masonry.
What They All Have in Common
None of these finishes fixes bad masonry. Before any of them we check for efflorescence (the white salt bloom that means water is moving through the wall), spalling brick faces, and open mortar joints. Repairs come first, and fresh mortar needs to cure, usually 28 days, before a coating goes over it. Then the wall gets a low-pressure wash, not a blast, and time to dry. The dry wall is the whole game in this climate. Every one of these finishes fails early when it goes on over moisture.
We also test. A two-foot sample panel on a side wall, looked at at noon and at dusk, tells you more than any photo on a phone. The paint visualizer is a good first pass for color, and the sample panel is the decision.
Questions We Hear Most
Can you limewash over painted brick?
No. Limewash needs bare, porous masonry to bond. Painted brick gets repainted or, in rare cases, stripped first.
Will whitewash or limewash protect the brick?
Limewash adds a little protection and does not trap water. Whitewash is a thin paint film and protects about as much as it seals, which is why detailing the wall matters more than the coating. Neither replaces fixing gutters, sills, and joints.
Which one lasts longest in Chicago weather?
Mineral stain, then limewash, because both are vapor-open and have no film to peel. Painted brick lasts well when the right breathable product is used over a dry, primed wall.
Can you do this in the fall?
Limewash and paint both want daytime temperatures above 50 degrees and no freeze overnight while they cure. Our season for brick runs late April through October.
How much does it cost?
It depends on the square footage, the condition of the masonry, and how much repair comes first, so Pete quotes every job in person after seeing the wall. The visit and the written quote are free.

Pete will come out, look at the brick, and tell you which of these makes sense for your house, including the honest answer when it is “leave it alone and tuckpoint.” Call (847) 564-4880 or request a free estimate.
