Making limewash paint requires just three ingredients: hydrated lime (or lime putty), natural earth pigments, and water. Mix 10 10 parts lime putty to 20 20 parts water, dissolve 1 1 part alum salt (as a binder), and add your pigment. Brush onto the wall in an X-shaped cross-hatch pattern.
Limewash is a natural, mineral-based paint made from crushed, heated, and slaked limestone, mixed with water, and typically tinted with natural earth pigments. Because it contains no synthetic binders, it dries to a distinctive, matte, and chalky finish with a subtle, cloudy texture.
Mineral paint is a great choice instead of traditional limewash paint. It gives a chalky, matte look but with more color options. Interior designers love it for its versatility and easy use.
Lime wash is a watered-down lime paint that is used only in one application. It is a whitewash or lime wash and is usually runny If it is overly watered down, water streaks may result, making it difficult to use. and may be difficult to use if it is too watered down too much causing water streaks.
Yes, you can achieve a "faux" limewash effect using regular latex or acrylic paint, though true limewash is made from crushed limestone. To do this, use a flat-finish paint and a specialized brush, applying a watered-down mixture in a crisscross pattern.
Slowly add powders, (lime, pigment or additive) to water, not water into powder to minimize dust. Avoid inhaling airborne powder during mixing and USE A DUST MASK! Mix only the amount of limewash to be used in one day. Larger quantities should be mixed with a paint paddle mounted to an electric drill.
❌ Cons of Limewash
Sensitive to Moisture Early On: Needs time to cure properly—avoid touching or cleaning it too soon. Limited Color Control: Pigments are subtle; don't expect paint-like saturation. Reapplication Over Time: It weathers naturally—some people love the patina, others see it as wear.
Lime Wash Myth #4: Limewash can kill mold. Romabio Answer: Not exactly true. Limewash paint that is made with authentic slaked lime has a very high pH, which creates a mold and bacteria-resistant surface as mold and bacteria cannot grow on it.
Natural Longevity. Limewash can last anywhere from 5 to 15 years, depending on: The number of coats applied. Surface prep quality.
No, you do not need specialty limewash paint to get a limewash look. While authentic limewash creates a highly breathable, matte finish, you can easily create a beautiful, budget-friendly "faux" limewash effect using regular flat or matte wall paint.

This light neutral welcomes you into the room with its subtle warmth. This highly versatile hue pairs with a broad spectrum of shades.
While both finishes soften masonry, whitewash is made of diluted latex paint that sits on the surface, while limewash is a natural limestone-and-water mixture that penetrates and calcifies within the brick. Whitewash offers a bright, opaque finish, whereas limewash creates a chalky, matte look that ages gracefully.
Whether you choose the texture of Limewash or the depth of Lime Paint, 2026 is the perfect year to make your home feel more authentically you.
To achieve the beautiful, textured, and matte look of limewash without the high cost or maintenance, your best alternatives are Roman clay, clay paint, or a DIY faux paint technique. These options provide the same old-world depth without limewash's tendency to fade or chalk.
A standard, traditional limewash formula uses a ratio of 1 part hydrated lime powder to 2 parts water. To mix, slowly add the hydrated lime to the water while stirring thoroughly with a paddle drill attachment until the mixture reaches the consistency of skim milk or thin pancake batter.
Size of the Wall
The cost to limewash interior walls is $1.50 to $6 per square foot. Naturally, if you're working with larger surface areas, the price will increase. Limewashing multiple different rooms that total 1,000 square feet, for example, can cost up to $6,000.
It's a natural color variation that occurs when exterior walls with an application of limewash get wet. Basically it will look slightly darker when it rains and with a heavily distressed finish, some of the original brick may shine through.
Achieve the textured, Old-World look of traditional limewash without the high cost or specialty materials by using regular flat/matte latex paint. This "faux" technique uses a two-tone color blend and loose brushstrokes to create soft, cloudy, and luminous depth on your walls.
Limewash does not strictly need to be sealed. Leaving it unsealed preserves its natural, matte, and breathable qualities. However, sealing it is highly recommended if the limewash is in a high-traffic space, a kitchen, a bathroom, or an area exposed to moisture.
Lime is highly alkaline, which means it disrupts the bodies of many garden pests, including flea beetles, aphids, and fungal pathogens. Its corrosive nature damages the exoskeletons of insects, causing them to dehydrate and die.
Limewash is not waterproof, but it is water-resistant and breathable. Its porous nature allows moisture to evaporate, preventing trapped water from damaging the underlying material. While it will darken when wet, it dries back to its normal appearance.
To permanently kill black mold, you must eliminate the mold roots in porous materials and fix the underlying moisture source. No chemical kills roots inside porous drywall or wood; heavily infested materials must be removed. Otherwise, use a 3% hydrogen peroxide solution or distilled white vinegar.
While both finishes soften masonry, whitewash is made of diluted latex paint that sits on the surface, while limewash is a natural limestone-and-water mixture that penetrates and calcifies within the brick.

Yes, you typically need to prime before applying limewash, but it depends entirely on your wall's current surface. Limewash relies on absorption to adhere, so non-porous or glossy surfaces require a mineral-based bonding primer or prep-coat.
Limewash has surged in popularity because it offers a sustainable, non-toxic, and breathable finish that creates a textured, soft, and "lived-in" matte look. Its rise is driven by the desire for earthy, organic textures over flat paint, offering a romantic, Old World, or modern rustic aesthetic. It is valued for its eco-friendly, mineral-based, and hypoallergenic properties.
