Limewash has been used for centuries as a breathable, protective finish for plaster, stone, and wood. It’s known for its unique, weathered look and inherent durability. But what happens when you want to change up your aesthetic? Can you paint over limewash? This question might have crossed your mind if you are considering a color change or a different finish for your space. In this article, we will explore the complexities and considerations when it comes to painting over limewash.
Can You Paint Over Limewash?
Certainly! While it is possible to paint over limewash, there are a few considerations to keep in mind. Limewash is porous, meaning it absorbs and releases moisture; hence, it’s vital to use a breathable paint to avoid trapping moisture. Additionally, the alkaline nature of limewash may affect some paints, so it’s recommended to use a primer first. This process properly preps the wall for the fresh paint, guaranteeing improved adhesion and long-lasting vibrancy of the new color.
It is important to be aware that painting over limewash will result in the loss of its distinctive ‘bloom’ and its ability to naturally repair minor cracks. Therefore, while it’s possible to paint over limewash, it’s crucial to weigh up the pros and cons and consider the impact on both the aesthetic and durability of your walls.
How Does Limewash Affect Normal Paint?
Limewash’s natural composition creates a unique interaction when normal paint is applied over it. Its porous nature, as mentioned earlier, can affect the adhesion of regular paints that aren’t designed to be breathable. This could result in peeling or blistering of the paint layer over time as moisture from the underlying limewash tries to escape. Furthermore, limewash’s highly alkaline attributes can lead to a reaction with certain types of paint, potentially causing discoloration or weakening the paint’s binding ability. Consequently, it’s essential to use a suitable primer that can interact favorably with both the limewash and the new paint. Note, however, that any applied paint will completely cover the limewash, negating its unique aesthetic effects and some of its practical benefits like the ability to self-heal minor cracks. [1]
What Primer to Use over Limewash?
When painting over limewash, it’s crucial to choose a primer that’s compatible with both the limewash and your chosen paint. A good option is a high-quality, acrylic-based primer. These primers are known for their excellent adhesion, breathable properties, and resistance to alkaline surfaces like limewash. Consider a product such as the Sherwin-Williams Loxon Conditioner, which is designed for masonry and can work well with lime washed walls. Its breathable finish will allow moisture from the limewash to evaporate, preventing paint failure. However, it’s always recommended to consult with a paint professional or the paint manufacturer directly when making your decision.
How to Paint over Limewash?
Painting over limewash involves several key steps to ensure a successful and lasting finish.
Clean the Surface

Limewash is considered a semi-permanent finish, known for its remarkable durability and longevity. As a mineral-based paint, it adheres powerfully to masonry surfaces, creating a hard, protective layer that can last for decades. However, while it is highly resistant to peeling and chipping, limewash naturally wears away over time, slowly fading and developing a patina that many find aesthetically appealing. This weathering process contributes to the belief that limewash is not entirely permanent, as its appearance will change over time. It’s important to note that the longevity of limewash can be influenced by several factors including the quality of the application, the condition of the surface, and the exposure to environmental conditions. But with proper maintenance, a limewashed surface can retain its charm for many years.
Does vinegar remove limewash?
Yes, vinegar can be used to remove limewash due to its acidic properties. However, it may require a substantial amount of effort and multiple applications. It’s important to note that this method might be less effective on old limewash or on layers that have been built up over time. The process typically involves applying white vinegar diluted with water directly to the limewashed surface, allowing it to soak in, and then scrubbing the surface with a stiff-bristled brush. Protective gear should be worn during this process, as vinegar can irritate the skin and eyes. Additionally, care should be taken around plants or other surfaces that may be sensitive to vinegar. Always rinse the surface thoroughly with water after the vinegar treatment to neutralize the acidity. Please note that the success of this method can vary, and it may not be suitable for all surfaces or situations.
