How to lime plaster
In recent years, there has been a resurgence of interest in traditional building materials and techniques. Lime plaster is one such material that has gained popularity due to its natural qualities and aesthetic appeal. Unlike modern synthetic plasters, lime plaster is made from a blend of lime, sand, and water. It has been used for centuries and is prized for its durability, breathability, and ability to restore old buildings.
Lime plaster offers several advantages over other types of plasters. It is a highly breathable material, allowing moisture to escape from the walls, which helps prevent damp and mold issues. It also leaves a soft and smooth finish that is visually appealing. Lime plaster is also highly flexible, allowing for natural movement in the building’s structure while maintaining its integrity.
To lime plaster a wall, start by preparing the surface. Remove any loose or crumbling plaster and repair any cracks or inconsistencies. Apply a bonding agent to improve the adhesion of the lime plaster. Mix the lime plaster according to the manufacturer’s instructions, ensuring a smooth and even consistency. Apply the plaster using a trowel or hawk and trowel, working from the bottom up in thin layers. Allow each layer to dry before applying the next.
Once the lime plaster has fully dried, it can be polished to create a smooth and glossy finish. This can be done using a trowel or a polishing tool. Alternatively, a limewash or lime paint can be applied to enhance the appearance and protect the plaster. Regular maintenance, such as checking for any cracks or signs of damp, is important to ensure the longevity of the lime plaster.
Overall, lime plaster is a versatile and environmentally friendly option for both new construction and restoration projects. Its unique properties make it a popular choice among architects, builders, and homeowners who appreciate the beauty and heritage of traditional materials. So, if you’re looking to add a touch of character and elegance to your walls, consider lime plaster as a viable option.

Tips and Tricks for a Smooth Lime Plaster Finish
When it comes to applying lime plaster, there are a few tips and tricks that can help you achieve a smooth and professional finish. Here are some key points to keep in mind:
1. Prepare the surface: Before applying lime plaster, make sure the surface is clean and free from any dust or loose debris. Remove any nails or other protrusions that could interfere with the application process.
2. Use the right tools: Use a suitable trowel or hawk to apply the lime plaster evenly. A steel trowel can leave a smooth finish, while a wooden float can create a textured look. Experiment with different tools to find the finish you desire.
3. Apply in thin layers: Avoid applying thick layers of lime plaster, as this can result in cracking and a less smooth finish. Instead, apply the plaster in thin layers, allowing each layer to dry before adding another. This will promote better adhesion and reduce the risk of issues down the line.
4. Keep the plaster moist: Lime plaster needs moisture to cure properly, so it’s important to keep it hydrated during the drying process. Spraying the plaster with a fine mist of water can help prevent cracks and promote a smoother finish.
5. Use a technique: Rub the Finish – After the plaster has been applied, use a technique called “rubbing the finish” to achieve a smoother and more polished look. Gently rub the surface of the plaster in circular motions using a damp sponge or cloth. This will help remove any imperfections and bring out the natural beauty of the lime plaster.
6. Practice proper curing: After completing the lime plaster application, it’s important to allow it to cure properly. This may involve covering the plaster with a plastic sheet or damp cloth to retain moisture. Avoid exposing the plaster to direct sunlight or drafts, as this can lead to uneven drying and potential cracking.
7. Seal the plaster: Once the plaster has fully cured, consider applying a suitable sealer to protect and enhance the finish. A sealer can also help make the plaster more water-resistant, which is especially useful in areas prone to moisture or high humidity.
By following these tips and tricks, you can achieve a smooth and professional lime plaster finish that will add beauty and durability to any interior or exterior space.
