Limewash is a centuries-old technique that has recently regained popularity as a charming and elegant way to enhance the exterior of brick buildings. Its unique qualities and aesthetic appeal make it a preferred choice for homeowners and architects looking to add character to their structures. In this article, we will explore the benefits of using limewash brick exteriors, provide a step-by-step guide on how to apply it, offer tips for achieving the desired look, and discuss important considerations. So, if you’re considering giving your brick exterior a makeover, read on to discover the beauty and benefits of limewash.


Limewash is a traditional paint-like mixture made from slaked lime, water, and natural pigments. It has been used for centuries as a protective and decorative coating for exterior and interior surfaces. Unlike modern paint, which covers the surface, limewash reacts with the underlying material, creating a unique and breathable finish. This allows the brick to maintain its natural texture and appearance while providing protection against the elements.


The Benefits of Limewash Brick Exterior

1. Enhances the Appearance

One of the primary reasons people choose limewash for their brick exteriors is its ability to enhance the appearance of the building. The translucent nature of limewash allows the natural color and texture of the brick to show through, creating a soft and inviting look. It adds depth and character to the facade, giving it a timeless appeal that complements various architectural styles.

2. Allows Breathability

Brick is a porous material that needs to “breathe” to maintain its structural integrity. Unlike conventional paint, which forms a film on the surface and inhibits breathability, limewash allows the brick to release moisture and prevents the buildup of trapped moisture that can lead to deterioration. This breathability feature makes limewash an excellent choice for older or historic brick buildings.

3. Protects Against Weathering

In addition to enhancing the appearance of brick, limewash provides a protective layer against weathering. It acts as a sacrificial barrier, shielding the brick from harsh elements such as rain, UV radiation, and pollution. The alkaline nature of limewash also deters the growth of mold and mildew, helping to maintain a clean and healthy exterior.

4. Eco-Friendly Option

For those who prioritize sustainability and environmentally-friendly solutions, limewash is an ideal choice. It is a natural and non-toxic material made from slaked lime, which is derived from limestone. Limewash is free from harmful chemicals typically found in conventional paints, making it a safe option for the environment, humans, and pets. Additionally, limewash is biodegradable and can be easily removed without causing any harm to the surroundings.

How to Apply Limewash Brick Exterior

Now that you understand the benefits of using limewash on your brick exterior, let’s delve into the step-by-step process of applying it.

1. Preparing the Surface

Before applying limewash brick exterior, it’s crucial to prepare the surface properly. Start by cleaning the brick thoroughly to remove any dirt, debris, or loose mortar. Use a stiff brush or a power washer to ensure a clean and smooth surface. If there are any cracks or damages, repair them before proceeding.

2. Mixing the Limewash

Next, you’ll need to mix the limewash. The ratio of lime to water will depend on the specific product you’re using, so be sure to follow the manufacturer’s instructions. Typically, you’ll need to mix the powdered lime with water until you achieve a smooth and creamy consistency. Use a bucket and a whisk or a mixer to blend the ingredients thoroughly.

3. Applying the Limewash

Once the limewash mixture is ready, it’s time to apply it to the brick. Start from the top and work your way down, applying an even coat using a brush, roller, or sprayer. It’s essential to work in small sections to ensure consistent coverage and avoid drying lines. If you prefer a more textured look, you can experiment with different application techniques such as brushing or sponging.

4. Curing and Maintenance

After applying the limewash brick exterior, allow it to cure for at least 24 to 48 hours. During this time, it will undergo a process called carbonation, where it reacts with the carbon dioxide in the air and hardens. Avoid any contact with water or moisture during the curing period.

Once the limewash has fully cured, it’s important to maintain it properly. While limewash is durable, it may require periodic touch-ups or recoating depending on the climate and exposure to elements. Regularly inspect the surface for any signs of wear or damage, and address them promptly to ensure the long-lasting beauty and protection of your limewashed brick exterior.

Tips for Achieving the Desired Look

To achieve the desired look and make the most of your limewashed brick exterior, consider the following tips:

1. Choosing the Right Color

Limewash comes in a variety of colors, ranging from traditional whites and neutrals to bolder shades. Consider the architectural style of your building, the surrounding environment, and your personal preferences when selecting a color. You can also create custom colors by mixing pigments with the base limewash brick exterior.

2. Testing on a Small Area

Before applying limewash to the entire surface, it’s recommended to test it on a small, inconspicuous area. This allows you to assess the color, texture, and overall effect of the limewash on your specific brick. Make adjustments if needed before proceeding with the full application.

3. Applying Multiple Coats

For a more opaque or vibrant look, you can apply multiple coats of limewash. Allow each coat to dry before applying the next, and remember that the color will deepen as the limewash cures.

4. Experimenting with Techniques

Don’t be afraid to experiment with different application techniques to achieve the desired texture and visual interest. You can use brushes, sponges, or even ragging techniques to create unique effects and variations in color and intensity.

Other Considerations

While limewash is a versatile and attractive option for brick exteriors, there are a few additional considerations to keep in mind.

1. Removing Limewash

If you ever decide to remove the limewash from your brick exterior, you can do so by using a power washer or a combination of scraping and washing. It’s important to note that removing limewash can be a labor-intensive process, so consider it a permanent application and ensure you’re committed to the look before proceeding.

2. Durability and Longevity

Limewash is a durable option for brick exteriors, but its longevity will depend on various factors such as climate, exposure to elements, and maintenance. With proper care and periodic touch-ups, a limewashed brick exterior can retain its beauty for many years.

3. Professional Assistance

While applying limewash can be a DIY project, it’s worth considering professional assistance for larger or more complex structures. Professional painters experienced in working with limewash can ensure a seamless and high-quality finish, saving you time and effort.


Limewash brick exterior offers a beautiful and eco-friendly solution for enhancing the appearance and protecting brick buildings. Its unique qualities, including breathability and natural charm, make it a preferred choice for homeowners and architects alike. By following the step-by-step application process, considering tips for achieving the desired look, and keeping important considerations in mind, you can transform your brick exterior into a timeless and elegant masterpiece.
