Limewash has gained a popular following in recent years with both professional designers and home enthusiasts alike. It is celebrated for its natural and timeless aesthetic, and it provides a one-of-a-kind way to enhance and soften the appearance of hard surfaces such as brick or stone.
Its application enhances a variety of interior and exterior spaces with an understated elegance that blends seamlessly with various architectural styles while creating a warm, inviting atmosphere. As a versatile and eco-friendly option, limewash appeals to everyone seeking both beautiful and sustainable solutions in their lives.
What is Limewash?
Limewash is a type of paint or whitewash that contains lime (calcium hydroxide), water, and, in some cases, natural pigment for color. Limewash has been used for centuries to change the color of a surface, particularly on the exterior of historic and traditional buildings.
Limewash is distinguished by its matte, chalky finish, which adds color, depth, and texture to surfaces. Unlike traditional paint, limewash allows the exterior surface to breathe, which prevents moisture buildup. This feature protects the integrity of the material beneath the limewash, allowing it to remain strong and durable over time. It is ideal for moist climates because it naturally prohibits the growth of bacteria that can form mold. Limewash has no VOCs or odor and is also UV resistant.
Types of Limewash
There are several different types of limewash, each with its own unique properties and applications. Limewash is classified primarily according to its composition and intended use.
- Traditional Limewash: This limewash is composed of lime and water. Traditional limewash is naturally white and is preferred for historic applications due to its authentic look and breathability. It is appropriate for both indoor and outdoor applications.
- Modern Limewash: The modern limewash variation often includes additional additives and binders to improve its adhesion. It still has an authentic appearance, but it is easier to apply and more weather-resistant.
- Colored Limewash: This is a traditional limewash with natural pigment added. These natural pigments include ochre, yellow iron oxide, red ochre, burnt sienna, and natural sienna. The colors added to limewash increase design flexibility while maintaining the natural, matte appearance of traditional limewash.
- Premixed Limewash: Premixed limewash, also known as ready-mixed limewash, is quick and easy to use, making it suitable for both professionals and DIYers. Unlike standard limewash, which is available in powder form, this mixture already contains water. The proper ratio of lime, water, and natural pigments ensures consistent quality and ease of application.
- Textured Limewash: This limewash contains aggregates or additives in the mixture that give the finished surface a more pronounced texture. It is used to create a rustic look or to replicate the appearance of traditional plaster.
- Acrylic-Modified Limewash: This type of limewash contains acrylic modifiers, which improve the durability and flexibility of the finish. These additives make limewash more suitable for high-traffic and weather-prone areas by combining the appearance of traditional limewash with the durability of modern paint.
Uses for Limewash
Limewash can be applied to a variety of surfaces, both indoors and outdoors. Its versatility and breathability make it suitable for a wide range of applications. Limewash adheres well to porous surfaces even without a primer, but a primer may be required for better adherence to non-porous surfaces.
- Exterior Walls: Limewash is ideal for exterior brick, stone, and stucco walls. It gives them a soft, matte-like texture and allows them to breathe, preventing water from becoming trapped beneath the surface and eroding their structure.
- Interior Walls: Limewash can be used on plaster and drywall walls that have been painted or left bare. Limewash is also effective on stone and brick interior walls. The limewash adds texture, interest, and a traditional look.
- Fireplace and Chimney: Limewash is ideal for heat-resistant surfaces such as fireplaces and chimneys. It can also be used to update the look of an outdated brick or stone fireplace.
- Wood: Limewash can be applied to a variety of wood items, including beams, paneling, and furniture, to create an aged and rustic look.
- Garden and Landscape Features: Limewash is ideal for creating a cohesive and natural appearance on outdoor garden elements, such as walls, containers, statuary, and fences.
Tips for Applying Limewash
You apply limewash in the same way you would paint, but the application will vary depending on your surface. Gather all of your supplies, including a limewash brush, primer (depending on the surface), and limewash. A primer will always be used on non-porous surfaces where limewash may not adhere well.

Apply the limewash in thin layers with horizontal, vertical, or diagonal strokes, then work it in with a circular motion. Begin by working in a small area and progressing to larger areas as you complete them. Be aware of drips and sagging in the limewash areas you have painted, and fix them as you go. The number of layers used determines the opacity of the limewash covering.
Limewash Finish Options
Limewash offers a variety of finishes, each with its own unique aesthetic and texture. The type of finish achieved depends on factors such as the application technique, the number of coats, and the type of surface being treated. Here are some common finishes that can be achieved with limewash:
Smooth Finish
A smooth finish is achieved by applying limewash in thin layers until the surface is smooth and opaque. This finish has a subtle texture and a soft, matte appearance that is ideal for creating a clean, modern surface.
Textured Finish
A textured finish is achieved by using a thicker limewash or one with added aggregates. This results in a surface with a more noticeable texture, giving it an aged or historic appearance.
Brushed Finish
A brushed finish can be achieved by applying thick limewash and creating visible brushstrokes in the medium. This adds texture and depth to the limewash while also creating a sense of movement.
Washed Finish
A washed finish is a technique that gives surfaces a soft, weathered appearance with subtle color and texture variations. Depending on the opacity desired, this finish can be achieved by applying diluted limewash or a single layer.
Layered Finished
Layered finishes are achieved by applying multiple layers of limewash in different colors. Each layer is partially visible through the other layers, adding depth and richness to the surface color.
Distressed Finish
A distressed finish is created by lightly sanding or scrubbing sections after the limewash has dried. This exposes the underlying material, giving the surface a worn or distressed appearance.
Limewash vs Paint
Limewash and paint are both suitable for covering walls, ceilings, and other surfaces. They both have advantages and disadvantages, so deciding which coating to use is a matter of personal preference, lifestyle, and surface.
Limewash is especially effective on exterior surfaces made of brick and stone because it sinks into the porous surfaces and allows them to breathe. Paint coats and protects surfaces such as wood, but it also acts as a vapor barrier, trapping moisture inside porous materials such as brick and stone, causing them to disintegrate over time. Limewash works well in moisture-prone areas due to its natural antibacterial and antifungal properties. Limewash, unlike paint, weathers gracefully and can be reapplied without requiring extensive surface preparation. In short, limewash works better on exterior brick and stone, while paint is best for protecting exterior wood.
The choice between limestone and paint for interior spaces is largely a matter of personal preference and lifestyle. Limestone creates an interesting depth and texture for walls. It is also an eco-friendly option, as it emits no VOCs and improves air quality. Limewash is less durable than paint because it is prone to washing away, which can be a problem in high traffic areas, and the color options are limited. Paint is highly durable for interior surfaces and comes in a wide range of colors and finishes.
