FAQ
Lime plaster boasts a rich history, with its use dating back thousands of years to ancient civilizations such as the Egyptians and Romans. Lime Plaster was used in architecture as an early form of concrete. Lime plaster was used to create a strong, long lasting finish. It is resistant to mold with ability to regulate moisture that made it ideal for historical buildings. Embracing lime plaster today not only connects us to a rich architectural heritage but also aligns with contemporary values of sustainability and timeless design.
In short:
Lime plaster is natural, breathable, and has a softer, more organic look while modern plaster is faster and more uniform but less breathable.
Here’s a simple comparison between Lime Plaster and plaster:
Lime Plaster
• Base Material: Made from lime (calcium hydroxide).
• Drying Time: Slower to dry and cure (carbonates over time).
• Breathability: Highly breathable—allows moisture to escape.
• Flexibility: More flexible; less likely to crack.
• Use: Traditional buildings, natural interiors, eco-friendly projects.
• Finish: Soft, matte, slightly textured; can look like stone or concrete.
Plaster (General/Modern Plaster)
• Base Material: Usually made from gypsum or cement.
• Drying Time: Dries quickly.
• Breathability: Less breathable.
• Flexibility: Can be more brittle over time.
• Use: Common in modern construction for walls and ceilings.
• Finish: Smooth and consistent.
Our Plaster Paint (lime plaster) is a distinctive, DIY-friendly product available in powder form, designed for easy application with a paintbrush, followed by a sponging technique, rather than traditional tools like spatulas or trowels. This approach simplifies the process, making it accessible for both professionals and home enthusiasts seeking to achieve a refined, natural finish.

Our Plaster Paint and Lime Paint each offer unique finishes, allowing you to achieve a variety of textures and visual effects in your space.
Plaster Paint: Rich Texture and Depth
Plaster Paint is applied in thicker layers, enabling you to build up substantial texture and depth on your surfaces. This application technique results in a finish that closely resembles natural stone or concrete, providing a tactile, sculptural quality to walls. The thicker consistency allows for creative expression, as you can manipulate the surface to achieve the desired level of texture and dimension.
Lime Paint: Subtle, Cloudy Aesthetic
In contrast, Lime Paint is applied in thinner coats, producing a soft, matte finish with a cloudy or shadowy appearance.This effect is achieved through the natural variation in pigment absorption, creating a nuanced, aged look that adds depth and character to any room. Lime Paint is ideal for those seeking a more understated, elegant finish that highlights the natural beauty of the material.
By understanding the distinct characteristics of Plaster Paint and Lime Paint, you can select the appropriate product to achieve your desired aesthetic—whether it's the robust, textured appearance of plaster or the delicate, variegated finish of lime paint.
When applying our Plaster Paint using a paintbrush, it's important to note that its thicker consistency results in a heavier feel during application and less spreadability compared to Lime Paint. Consequently, you may need to reload your brush more frequently from the bucket. Despite these differences, the application technique remains consistent with that of our Lime Paint.
Apply the Plaster Paint using "X-strokes" this technique helps achieve a uniform, textured finish. Due to the paint's viscosity, stretch it as far as possible with each stroke, maintaining a wet edge to avoid lap marks. Ensure the paint is thoroughly mixed to maintain consistency and color uniformity throughout the application and allow adequate drying time between coats, followed by sponging after second layer has dried out in order to smooth out and enhance the effect. By adhering to these practices, you can effectively apply Plaster Paint to achieve a professional and aesthetically pleasing finish.

The drying time of Plaster Paint is influenced by factors such as temperature, humidity, surface material, and layer thickness. Typically, the first layer dries within 2 to 4 hours, during which the color lightens as it sets. This allows you to apply the second layer, which usually requires 4 to 6 hours to dry completely. However, these times can vary based on environmental conditions and application specifics.
Additional Considerations:
- Surface Material: Porous surfaces may absorb more moisture, potentially extending drying times, while non-porous surfaces might allow for quicker drying.
- Layer Thickness: Thinner layers generally dry faster than thicker ones.
- Environmental Conditions: High humidity can slow down the drying process, whereas low humidity and higher temperatures may accelerate it.
Curing vs. Drying:
It's important to distinguish between drying and curing:
- Drying: The process where the plaster loses moisture and becomes firm.
- Curing: The chemical process that strengthens the plaster over time.
While drying may occur relatively quickly, curing is a prolonged process allowing at least 1 month of curing time for every 5 mm of plaster depth.
Recommendations:
- Patience: Allow each layer to dry thoroughly before applying the next to ensure proper adhesion and finish quality.
- Environmental Control: Maintain stable temperature and humidity levels to facilitate optimal drying and curing conditions.
- Surface Preparation: Ensure surfaces are clean and appropriately prepped to promote even drying and reduce potential issues.
By considering these factors and allowing adequate drying and curing times, you can achieve a durable and aesthetically pleasing plaster finish.
To prepare your Plaster Paint mixture, begin by mixing the Lime Paint color according to the instructions on the packaging (by combining 1 kg of Lime Paint powder with 1.7 liters of water)
Once the Lime Paint is thoroughly mixed, gradually add the 2 kg of Plaster Paint raw powder to the bucket without additional water. Stir the mixture well to achieve a smooth, homogeneous consistency and continue stirring periodically during use to maintain a consistent texture. This method ensures an even and workable paint mixture, facilitating a smooth application process.
Achieving the ideal consistency for your Plaster Paint mixture is essential for a smooth and efficient application. If the mixture becomes too thick over time, possibly due to water evaporation, you can adjust its consistency as follows:
Adjusting Paint Consistency:
- Adding Water: Introduce a small amount of water gradually, stirring thoroughly after each addition, until the paint reaches a workable consistency. Aim for a thickness where the brush can be dipped easily without excess dripping.
First vs. Second Layer Application:
- First Layer: Apply the paint at the consistency described above, ensuring even coverage and a solid base.
- Second Layer: It's common for the second layer to absorb more, requiring a slightly thinner mixture. Adjust the paint's consistency by adding a touch more water, as needed, to facilitate smoother application.
- Stirring: Regularly stir the paint during application to maintain a uniform texture and prevent settling.
Applying both layers of Plaster Paint on the same day is not mandatory. You can comfortably apply the second layer the following day or at a later time that suits your schedule. However, it's crucial to complete the entire surface area—be it a wall or ceiling—in one continuous session. Stopping midway can lead to noticeable color variations and an uneven finish.
Storing Mixed Plaster Paint:
If you need to pause your project and store the mixed Plaster Paint, proper storage is essential to maintain its quality. Ensure the paint is stored in an airtight container to prevent it from drying out.
It's advisable to use freshly mixed Plaster Paint on the same day to achieve optimal results. If you need to store the paint for use the following day or later, follow these guidelines:
Storage Recommendations:
- Airtight Sealing: Store the paint in a tightly sealed, airtight container to minimize exposure to air, which can cause the paint to thicken and harden.
- Surface Layer: Adding a thin layer of water on top of the paint before sealing can help prevent it from drying out.
- Storage Conditions: Keep the container in a cool, dry place, away from extreme temperatures, as heat can accelerate drying and cold can affect the paint's consistency.
Reusing Stored Paint:
- Stirring: Before use, thoroughly stir the stored paint to ensure a smooth, lump-free consistency.
- Adjusting Consistency: If the paint has thickened, gradually add small amounts of water, stirring well after each addition, until it reaches a workable consistency.
Considerations:
- Volume and Surface Area: Larger volumes of paint tend to maintain their consistency better than small amounts, which may dry out more quickly.
- Time Frame: While stored paint can be usable after a day or a few days, it's best to use it within a short time frame to ensure quality results.
By following these storage and reuse guidelines, you can maintain the quality of your Plaster Paint for subsequent applications.
While sponging the surface after applying the second layer of Plaster Paint is not required, it can significantly enhance the final aesthetic by adding depth and refinement.
Optional Sponging Technique for Enhanced Finish;
Once the second layer has been applied and the Plaster Paint begins to set—when water has just started to evaporate—we begin the sponging process. Using a damp sponge in gentle circular motions, we smooth out visible brush strokes and lightly press the surface to create a more even finish. Some loose sand may fall during this step, so protective eyewear is recommended to prevent irritation. The sponge should be slightly damp if the paint is still moist, or a bit wetter if the surface has started to dry. The goal is to move and shape the paint without removing it. If the paint comes off easily, it’s too early to begin.
Timing varies depending on how quickly the paint dries, so stay attentive to the surface conditions. In some areas, results will appear immediately, while in others the effect may be more subtle—this is completely normal.
Trust the process. Whether you sponge every area perfectly or not, your Plaster Paint finish will reveal a rich, organic texture with the timeless look of natural stone or concrete.
Applying Kalklitir's Plaster Paint requires careful surface preparation to ensure optimal adhesion and finish quality. Surfaces need to be stable, clean and free of grease, dust etc. Here's a comprehensive guide to suitable surfaces, priming recommendations:
Suitable Surfaces for Plaster Paint:
- Mineral Absorbent Surfaces: Ideal for materials like bricks and concrete.
- Previously Painted Surfaces: Compatible with walls painted with water-based, matte, or semi-matte paints.
- Existing Lime Paint or Plastered Surfaces: Can be applied over surfaces previously treated with Kalklitir's Lime Paint or fully plastered areas.
Considerations for Absorbent Surfaces:
- Surfaces like Lime Paint or plastered walls may absorb more paint, potentially requiring additional coats for full coverage. In such cases, applying a primer is advisable to promote even absorption and prevent discoloration.
When to Use a Primer:
- Uncertain Surface Composition: If the surface has been patched with materials to fix joints, cracks, holes etc. or surfaces are of unknown composition or they have oil-based paints, it's prudent to apply a primer to ensure proper adhesion.
- Wallpapered Surfaces: Before applying Plaster Paint over wallpaper, a primer is essential. It is very important to ensure the wallpaper is securely attached, as the weight of two thick layers of Plaster Paint may affect its adhesion.
Recommended Primers:
- Kalklitir's Primer: A water-based product suitable for various surfaces, including water-based painted surfaces, lime paint, alkyd-based paints, concrete, plaster, gypsum, MDF, and plywood. It aids in achieving even absorption and reducing the risk of discoloration.

Plaster Paint generally offers a more durable surface. This enhanced durability is attributed to the thicker consistency and application of Plaster Paint, which results in a robust and resilient finish. It's important to note that while Plaster Paint offers increased durability, both Plaster Paint and Lime Paint share benefits such as breathability and natural composition.
Applying Kalklitir's Top Coat over Plaster Paint (and Lime Paint) provides an additional protective layer, enhancing resistance to stains and moisture. However, it's important to understand the implications for the material's breathability:
Application Guidelines:
- Drying Time: Allowing Plaster Paint to cure for at least 72 hours (3 days) and preferable up to 7 days before applying Top Coat is recommended to ensure proper hardening and bonding. This waiting period allows the plaster to fully set, reducing the risk of issues like cracking or peeling that can arise from painting over insufficiently dried plaster.
- Breathability Considerations: While the Top Coat offers protection, it may reduce the material's breathability. This could potentially affect moisture regulation within the wall structure. It's essential to balance the need for protection with the desire to maintain breathability.
Considerations:
- Moisture Evaporation: During the initial drying phase, moisture evaporates from the plaster. Applying a top coat too soon can trap residual moisture, potentially leading to paint adhesion problems and surface imperfections.
- Surface Hardening: Waiting allows the plaster to harden adequately, providing a stable and durable foundation for the top coat. This enhances the longevity and appearance of the finished surface.
Recommendations:
- Assess Necessity: Determine whether the protective benefits of the Top Coat align with your specific needs, considering the potential impact on breathability.
Application of Top Coat:
- Thin Layers: Apply the Top Coat in thin, even layers. This approach ensures better adhesion and a smoother finish.
- Recommended Tools: Use a high-quality brush for application. Brushes provide better control, especially in corners and edges, ensuring a consistent coat. Kalklitir's lime brushes can be used and are available in our shop.
- Drying Time Between Layers: Allow each layer of Top Coat to dry completely before applying the next. This practice prevents issues like peeling or uneven texture.
